Description

  The present invention relates to a business process / business rule execution system that provides an execution environment for business processes and business rules that use Web services.

2. Description of the Related Art Conventionally, there has been known a Web service that includes a standard interface for functions of a computer system and that can use the computer system from another computer system.
There is also known a business process execution system that executes business process processing in cooperation with a plurality of Web services based on a business process (processing according to business specifications) that defines a certain process. This business process is a collection of interrelated tasks (a plurality of processes) that solve a specific problem.

This business process execution system defines the execution order of business processes as a business process definition body, and executes the business processes indicated by the processes of the constituent elements in the order indicated in the business process definition body (for example, patents) Reference 1).
This business process execution system usually performs business process-specific processing such as data retrieval, reading, writing, and editing in a database, and includes complex arithmetic processing (logical processing including judgment and comparison, processing including numerical operation, etc. ) Business rule specific processing cannot be executed.
For this reason, the conventional business process execution system defines business rules to be executed when executing business rule processing that performs complex arithmetic processing, and calls the business rule execution system from the business process execution processing. ing.

JP 2010-55562 A

As described above, since the conventional business execution system is configured so as not to perform complex arithmetic processing, a mechanism for executing complicated arithmetic processing on behalf of the business rule execution system or a function for performing complex arithmetic processing is provided. It is necessary to generate and implement specially for each business rule in business processing.
For this reason, when a business process, which is its main process, is executed in the conventional business execution system, an unnecessary load such as a call process of the business rule execution system is applied, and the operation of the business process is performed. There is a problem of inefficiency due to being cut off.

In addition, when a business process is input, the configuration that distributes the business process to either the business process execution system or the business rule execution system according to the content of the process that constitutes the business process corresponds to the business rule process in the business process. Individually, it is necessary for the worker to create the product in advance.
This distribution configuration is created for each business rule individually corresponding to the business rule processing, so the versatility is low. As the business process execution engine or business rule changes, the distribution configuration also needs to be changed. For this reason, there is a drawback in that the development man-hours of the worker increase.

  The present invention has been made in view of such circumstances, and it is not necessary to call the business rule execution engine from the business process execution engine as in the prior art, and is accompanied by a change in the business process execution engine or the business rule execution engine. An object of the present invention is to provide a business process / business rule execution system, business process / business rule execution and program capable of eliminating an increase in the work of an operator.

  The business process / business rule execution system of the present invention performs a process according to a business process execution engine that performs processing according to business process description information indicating a procedure of business process processing, and business rule description information that indicates a procedure of business rule processing. A business process / business rule execution system having a business rule execution engine and executing a web service process corresponding to a business process definition file defining one or a plurality of business processes or business rule processes. If the servlet that executes the process of the process and the rule identification information for identifying the business rule are described in the servlet, the delegation destination of the process of the servlet And Le execution engine, whereas, if the business rule identification information to said Servlet is not described, characterized in that the transfer destination of the processing of the servlet and a service adapter to the business process execution engine.

  In the business process / business rule execution system of the present invention, one service adapter is provided for all the processes, and process identification information for identifying a process to be processed by the servlet set in advance, It has a correspondence table showing correspondence with a servlet process processing delegation destination, and determines the servlet processing delegation destination according to the process identification information described in the servlet.

  In the business process / business rule execution system according to the present invention, the service adapter is provided in each of the processes, and a servlet process that matches the process identification information described in the service adapter is assigned to the assigned delegation destination. It is characterized by delegation.

  When the business process / business rule execution system of the present invention delegates processing between the servlet and the business rule execution engine, the interface format and data format of the delegation source interface are changed. When delegating processing between the business rule wrapper that converts the format and the data format, and the servlet and the business process execution engine, the delegation source interface format and the data format are designated as the delegation destination interface. And a business process wrapper for converting to a data format.

  The business process / business rule execution system of the present invention further includes a business rule definition file storage unit in which the business rule description information and the rule identification information indicating the business rule description information are stored correspondingly, When the business rule execution engine delegates processing from the servlet, the rule identification information described in the servlet is used as a search key, the business rule definition file storage unit is searched, and the same rule as the search key The business rule description information stored corresponding to the identification information is read out, and business rule processing is executed according to the procedure of the business rule description information.

  In the business process / business rule execution system of the present invention, when the own data is delegated to other servlets as the delegated data between the servlets, partner information indicating a partner to which the data is delegated is described in the servlets. The data is delegated to the servlet of the partner information via the temporary storage unit.

  The business process / business rule execution method of the present invention performs a process according to a business process execution engine that performs processing according to business process description information indicating a business process processing procedure, and business rule description information that indicates a business rule processing procedure. A business process / business rule execution method that has a business rule execution engine and executes web service processing corresponding to a business process definition file that defines one or a plurality of business processes or business rule processes. When each of the servlets provided in the process executes the process of the process, and when the service adapter describes rule identification information for identifying the business rule in the servlet, A business rule execution engine as a business rule execution engine, and, when the business rule identification information is not described in the servlet, a process process execution engine as a business process execution engine. To do.

  The program of the present invention has a business process execution engine that performs processing according to business process description information that indicates a business process processing procedure, and a business rule execution engine that performs processing according to business rule description information that indicates a business rule processing procedure. And a business process / business rule execution system that executes a web service process corresponding to a business process definition file that defines one or a plurality of business processes or business rule processes. Servlet means for executing the process of the process, and when the rule identification information for identifying the business rule is described in the servlet, the delegation destination of the process of the servlet is a business rule execution engine Whereas, if the business rule identification information to said Servlet is not described, a program for causing a transfer target of the process of the servlet service adapter means to business process execution engine as.

  According to this invention, since it has the service adapter that distributes which of the business process execution engine and the business rule execution engine execute the process depending on the presence or absence of the rule identification information, Unlike conventional systems, it is possible to suppress the inefficiency of business process processing operations without applying unnecessary load such as call processing of the business rule execution engine.

<Business process / Business rule execution system>
Hereinafter, a business process / business rule execution system according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a business process / business rule execution system according to an embodiment of the present invention.
In the business process / business rule execution system according to an embodiment of the present invention, for example, JAVA (registered trademark) is used as an operating environment.
The business process / business rule execution system includes a web server 2 and a server storage unit 3.

  Here, the web server 2 includes a business process execution engine 21, a business rules execution engine 22, a JSP (Java (registered trademark) Server Pages) module (hereinafter, JSP) 23, and a servlet. Module (hereinafter referred to as servlet) 24 (24A, 24B), service adapter (ServiceAdapter) module (hereinafter referred to as service adapter) 25, business process wrapper module (hereinafter referred to as business process wrapper) 26, business rule wrapper (Business Rules Wrapper) module (hereinafter referred to as “business rules wrapper” module) , Business rule wrapper) 27, DB (database) 210, and business rule definition file storage unit 200. A client (such as a personal computer as a user terminal) is connected to the web server 2 via a communication network including the Internet.

The server storage unit 3 stores the source code of each program of the JSP 23, the servlet 24, the service adapter 25, the business process wrapper 26, and the business rule wrapper 27 and a file describing the business in advance.
The file in which the source code of the JSP 23 is described is a JSP file, the file in which the source code of the servlet 24 is described is the servlet file 102, and the file in which the source code of the service adapter 25 is described is the service adapter file 103. The file in which the source code of the business process wrapper 26 is described is a business process wrapper file 104, and the file in which the source code of the business rule wrapper 27 is described is a business rule wrapper file 105. The generation of these source code files will be described later.
In addition, a business process definition body (XML) file 101 in which contents of processes performed by the business process execution engine 21 are described in the server storage unit 3 is set in advance (details will be described later).
Further, the server storage unit 3 stores a business process table of a combination of a business process name and a process identification number (process ID, that is, subsequent process identification information) constituting the business process of this business process name.

When accessed by the client, the web server 2 reads the program file of the JSP 23 from the server storage unit 3, instantiates it, and executes the JSP 23.
The JSP 23 is instantiated and executed, and then analyzes the JSP file supplied from the web browser installed in the client, for example, described in HTML (HyperText Markup Language), and identifies the process constituting the business process Information is extracted, and a servlet corresponding to the extracted process identification information is started.
That is, the web server 2 is supplied with a JSP file including data and information indicating which servlet is to be activated, that is, process identification information, from the client.
For example, the JSP 23 reads the servlet file 102 (JAVA (registered trademark) file in which the class is described) corresponding to the process identification information supplied from the client from the server storage unit 3, and is described in the read servlet file 102. Data is substituted into a variable and instantiated, and the servlet 24 (24A, 24B) is activated and executed as an object.

As a result, the JSP 23 generates and executes the servlets 24A and 24B for each JSP file (or for each user).
Here, in order for the web server 2 to identify the client, for example, a general session management function (PHP: Hypertext Preprocessor 4.0) is used for the instantiated servlets 24A and 24B, and a session ID is assigned as a session variable. Has been.
In the following description, the servlet 24A corresponds to a process to which rule identification information (rule ID) is added (described), and the servlet 24B corresponds to a process to which rule identification information is not added. Will be described.

When the servlet file 102 is instantiated and the servlet 24A (with rule identification information added) is generated as an object, the web server 2 generates a business rule wrapper file 105 (corresponding to the process identification information of the servlet 24A). A JAVA (registered trademark) file in which a class is described is read from the server storage unit 3 using the process identification information as a search key.
Also, the web server 2 substitutes necessary data into variables described in the read business rule wrapper file 105 to instantiate, and activates and executes the business rule wrapper 27 as an object.

Next, FIG. 2 is a diagram showing the concept of the interface and data format of the container that transmits and receives data when data is transmitted and received between the servlet 24 (for example, 24A) and the business rule execution engine 22. .
The business rule wrapper 27 includes an interface of a bean that is activated by the servlet 24A and includes data used for the process to be delegated when the servlet 24A delegates the business rule process to the business rule execution engine 22. And the format of data (total amount of reserved sales and total amount of reserved deposit) are converted into an interface and data (total amount of reserved sales and total amount of reserved deposit) that can be processed by the business rule execution engine 22. Further, since the servlet 24A is generated corresponding to the process in which the rule identification information is described and added (attached), in addition to the process identification information, the rule identification information corresponding to this process is also added to the started PaymentStatusBean. It is described and added (hereinafter referred to as addition).

That is, the business rule wrapper 27 converts the PaymentStatusBean interface and data format activated by the service adapter 25 into the business rule execution engine 22 format.
Then, the business rule wrapper 27 writes the converted PaymentStatusBean into an interface container (KSession) for delegating processing, thereby transferring data to the business rule execution engine 22, that is, delegating the processing. Here, the business rule wrapper 27 performs conversion of the PaymentStatusBean interface and data format in accordance with conversion conditions set in advance corresponding to the process identification signal corresponding to itself.

  On the other hand, in the business rule wrapper 27, when the business rule processing result is supplied from the business rule execution engine 22 to the servlet 24A, the processing result data is written from the business rule execution engine 22 to the PaymentStatusBean in the interface container (KSession). Then, the interface and data format of this PaymentStatusBean (process identification information and rule identification information of a process corresponding to the servlet 24A are added) are converted into a format in which the servlet 24A inputs data.

In other words, the business rule wrapper 27 converts the interface and data format of this PaymentStatusBean when the processing result data from the business rule execution engine 22 is written to the PaymentStatusBean of the interface container (KSession).
Then, the business rule wrapper 27 outputs the converted PaymentStatusBean to the service adapter 25.
Here, the business rule wrapper 27 performs conversion of the interface and data format of the interface container in response to the process identification signal corresponding to itself.

  Returning to FIG. 1, the web server 2 instantiates the servlet file 102 and starts the servlet 24B (no rule identification information added) as an object, so that the business corresponding to the process identification information of the servlet 24B is activated. A process wrapper file 104 (a JAVA (registered trademark) file in which a class is described) is read from the server storage unit 3 using the process identification information as a search key, and necessary data is substituted into variables described in the business process wrapper file 104 The business process wrapper 26 is activated and executed as an object.

Next, FIG. 3 is a diagram showing the concept of the container interface and data format for transmitting and receiving data when data is transmitted and received between the servlet 24 (for example, 24B) and the business process execution engine 21. .
The business process wrapper 26 includes an interface of a bean (Bean, for example, Reservation Bean) that is started by the servlet 24 </ b> B including data used for the process to be delegated when the servlet 24 </ b> B delegates the business process process to the business process execution engine 21. And the format of the data (reservation reservation number and reservation applicant name) are converted into an interface and data (reservation reservation number and reservation applicant name) that can be processed by the business process execution engine 21.

That is, the business process wrapper 26 converts the ReservationBean interface and data format activated by the service adapter 25 into the business process execution engine 21 format.
Then, the business process wrapper 26 writes the converted ReservationBean into an interface container (ServiceSession) for delegating processing, thereby transferring data to the business process execution engine 21, that is, delegating the processing. Here, the business process wrapper 26 performs conversion of the ReservationBean interface and data format according to conversion conditions set in advance corresponding to the process identification signal corresponding to itself.

  On the other hand, the business process wrapper 26 writes the processing result data from the business process execution engine 21 to the ReservationBean in the interface container (ServiceSession) when the business process execution result is supplied from the business process execution engine 21 to the servlet 24B. Then, the interface of the ReservationBean (the process identification information of the process corresponding to the servlet 24B is added) and the data format are converted into a format in which the servlet 24B inputs data.

That is, when the process result data is written from the business process execution engine 21 to the ReservationBean of the interface container ServiceSession, the business process wrapper 26 converts the interface and data format of the ReservationBean.
Then, the business process wrapper 26 outputs the converted ReservationBean to the service adapter 25.
Here, the business process wrapper 26 converts the interface container and the data format corresponding to the process identification signal corresponding to itself.

Returning to FIG. 1, the web server 2 reads one of the servlet files 102 from the plurality of servlet files 102 stored in the server storage unit 3, instantiates it, and executes it as an object. A file 103 (a JAVA (registered trademark) file in which a class is described) is read from the server storage unit 3.
Further, the web server 2 substitutes necessary data into variables described in the read service adapter file 103 to instantiate it, and activates and executes the service adapter 25 as an object.

The service adapter 25 has a correspondence table indicating the correspondence between the process identification information of the process corresponding to the servlet 24 and the engine identifier of the execution engine that delegates the processing of this process. When rule identification information is described in a process in a business process definition body (described in detail later), the business rule execution engine 22 is a transfer destination of the processing of the servlet 24A generated corresponding to this process. On the other hand, when the rule identification information is not described in the process in the business process definition body, the business process execution engine 21 is a transfer destination of the processing of the servlet 24B generated corresponding to this process.
Further, the service adapter 25 searches the correspondence table for the same process identification information as the process identification information described in the bean (ReservationBean or PaymentStatusBean) started by the servlet 24.
Then, the service adapter 25 uses the execution engine (the business process execution engine 21 or the business rule execution engine 22) indicated by the engine identification information stored in correspondence with the process identification information searched in the correspondence table to process the process. Set as delegation destination.

The business process execution engine 21 performs business process processing (for example, retrieval, reading, writing, and editing of data in the DB 210 (database)) based on the data written in the interface container (ServiceSession) and the process identification number.
When the servlet 24B executes a business process process as a process corresponding to the process with the process identification number “1” in the business process definition body described later, the process with the process identification information “1” performs a “search for a reservation basic” process. To do. That is, the business process execution engine 21 uses the reservation reservation number and reservation applicant name, which are data delegated from the servlet 24B, as search keys, and stores the data stored corresponding to the search keys in the DB 210. The data is searched (details of the process will be described later).

The business process execution engine 21 also stores the business process definition body (XML) file 101 stored in the server storage unit 3 based on the data added to the ReservationBean written in the interface container (ServiceSession) and the process identification information. The business process definition body (XML) file 101 to which the same process identification information is added is read from the inside.
In addition, the business process execution engine 21 processes the business process using data supplied from the servlet 24B via the ReservationBean according to the read business process definition body (XML) file 101.

On the other hand, the business rule execution engine 22 performs business rule processing (for example, arithmetic processing such as logical operation or numerical calculation) based on the data added to the PaymentStatusBean written in the interface container (KSession) and the process identification number.
When the business rule process is executed by the servlet 24A as a process corresponding to the process having the process identification number “2” in the business process definition body, which will be described later, the process having the process identification information “2” performs a “search for a deposit status” process. I do. In other words, the business rule execution engine 22 compares the reserved sales total and the reserved deposit total, which are data delegated from the servlet 24A, and the deposit status set according to the comparison result is provided internally. The status table is searched (details of the process will be described later).

Further, the business rule execution engine 22 uses the rule identification information written in the interface container (KSession) to identify the same process identification from the business rule definition file 302 stored in the business rule definition file storage unit 200. The business rule definition file 302 with the information added is read.
In addition, the business rule execution engine 22 performs business process processing using data supplied from the servlet 24A via the PaymentStatusBean according to the logical operation or numerical operation expression described in the read business rule definition file 302. Do.

In the present embodiment, the DB 210 is, for example, a travel management customer management database, and each reservation corresponds to a reservation reservation number, a reservation applicant name, a reservation departure date, a reservation employee name, and a reservation reservation date. Attached and memorized.
In the business rule definition file storage unit 200, a business rule definition file 302 in which the contents of the business rule processing executed by the business rule execution engine 22 is described. The rule identification information that uniquely indicates the business rule definition file 302. It is remembered with.

FIG. 4 is a diagram illustrating an example of the configuration of the process rule processing description in the business rule definition file 302.
The process rule process described in the business rule definition file 302 of FIG. 4 corresponds to the process of the servlet 24A already described, and compares the total reserved sales amount input as data with the total reserved deposit amount. The payment status set according to the comparison result is output.
As the deposit status in the business rule definition file 302, “not deposited”, “partial deposit”, “paid”, and “exceeded deposit” are set. The statuses in the business rule definition file 302 shown in FIG. 4 and the types of data comparison processing (process rule processing) have the following correspondence relationship.
・ Non-payment: When the total deposit amount is “0” ・ Partial deposit: The total deposit amount is not “0” and the total reservation sale amount is larger than the total reservation deposit amount ・ Payment: Reserved sale Total amount is equal to the total reservation deposit amount. ・ Deposits exceeded: The total reservation sales amount is smaller than the total reservation deposit amount.

  Next, the operation of the business process / business rule execution system according to the present embodiment will be described with reference to FIGS. 1 and 5. FIG. 5 is a sequence diagram showing the operation of the business process / business rule execution system when processing a process to which no rule identification information is added in the business process definition file.

Step S111:
A user accesses the web server 2 via a client. As a result, the web server 2 instantiates and executes the JSP 23.
The JSP 23 transmits a screen for inputting the type of business process and data used for this process to the client via a communication line such as the Internet (not shown).
The user inputs the type of business process displayed on the client display device and the data used for this business process in the input field. For example, as shown in FIG. 9, when the user inputs “search for a reservation basic” as business processing and inputs “reservation number” and “reservation applicant name” as data in the input field using a keyboard or the like, And a JSP file including “reservation number” and “reservation applicant name” input as data is transmitted to the web server 2 via a communication line.

Step S112:
The JSP 23 extracts the “reservation basics” of the business process, the “reservation number” and the “reservation applicant name” of the data from the JSP file input from the client, and this “searches the reservation basics”. The combination of process identification information corresponding to the business process (business process name) is searched from the business process name table of the server storage unit 3 using this business process name as a search key.
Then, the JSP 23 reads a combination of process identification information corresponding to the searched business process name, that is, a combination of process identification information “1”, “2”, and “3” from the business process name table.

The JSP 23 performs processing in the order of the process identification information “1”, “2”, and “3”, so the servlet file 102 corresponding to the process identification information “1” is read from the server storage unit 3 By substituting “reservation number” and “reservation applicant name” into variables and instantiating them, the servlet 24B is executed.
Similarly, the web server 2 reads the service adapter file 103 and the business process wrapper file 104 from the server storage unit 3 and instantiates them to execute the service adapter 25 and the business process wrapper 26.

Step S113:
The servlet 24B activates the bean object ReservationBean of the program for inputting and outputting data, and the process identification information “1” corresponding to its own process, the “reservation number” and “reservation applicant name” of the data, Substitute in this activated ReservationBean.
In other words, the servlet 24B starts up a ReservationBean for delegating the process of searching the DB 210 using its own data “reservation number” and “reservation applicant name” to the business process execution engine 21, Write the data necessary for delegation to the ReservationBean that started up.

Step S114:
When the ReservationBean is activated, the service adapter 25 extracts the process identification information “1” from the activated ReservationBean, and the delegation destination information indicating the delegation destination of the process indicated by the extracted process identification information “1” Are detected in the correspondence table set in itself.
The service adapter 25 delegates the process for the ReservationBean to the business process wrapper 26 because the delegation destination for the process identification information “1” in the correspondence table set in itself is the business process execution engine 21.

That is, the service adapter 25 performs control to delegate the process of the process identification information “1” from the servlet 24 </ b> B to the business process execution engine 21 via the business process wrapper 26.
Here, the service adapter 25 has the same process identification information as the process identification information added to the ReservationBean, that is, the business process execution engine 21 via the business process wrapper 26 to which the process identification information “1” is added. Control to delegate to.

Step S115:
Next, the business process wrapper 26 extracts process identification information from the ReservationBean.
Then, the business process wrapper 26 determines whether or not the extracted process identification information matches the process identification information set for itself.
Here, when the process identification information matches, the business process wrapper 26 converts the interface and data format of the “reservation number” and “reservation applicant name” data described in the ReservationBean.
Further, the business process wrapper 26 performs a process of placing the converted ReservationBean in a ServiceSession that is an interface container of the business process execution engine 21.
Through the above-described processing, the business process wrapper 26 converts the interface and data format corresponding to the servlet 24 </ b> B in the ReservationBean into the interface and data format in the data input of the business process execution engine 21. Further, the business process wrapper 26 adds a service ID as identification information to the ReservationBean obtained by converting the ReservationBean format.

Step S116:
Next, the business process execution engine 21 reads process identification information and data of “reservation number” and “reservation applicant name” from the ReservationBean in the interface container ServiceSession.
The business process execution engine 21 reads the business process definition body (XML) file 101 corresponding to the process identification number “1” from the server storage unit 3.

Then, the business process execution engine 21 executes the process of the business process having the process identification number “1” in accordance with the description of the read business process definition body (XML) file 101.
As described above, the “reservation number” and “reservation applicant name” of the data used for the “search reservation basic” process of the process with the process identification number “1” are sent to the interface container ServiceSession to the business process execution engine 21. Via Servlet 24B.

The business process execution engine 21 uses the data “reservation number” and “reservation applicant name” supplied from the servlet 24B as search keys in accordance with the description of the business process definition body (XML) file 101. A business process process for searching for data corresponding to the data from the DB 210 is executed.
At this time, the business process execution engine 21, for example, “reservation reservation number” and “reservation application” in which some characters in the character strings of “reservation number” and “reservation applicant name” supplied as search keys match. The “person name” reservation data is extracted from the plurality of reservation data stored in the DB 210.
Next, the business process execution engine 21 performs a search using the supplied “reservation number” and “reservation applicant name” as search keys. As a result, “reservation reservation number” and “reservation application” which are extracted reservation data are searched. “Reservation Name”, “Reservation Employee Name”, “Reservation Reservation Date”, and “Reservation Departure Date” from the ReservationBean placed in the interface container ServiceSession, identify the ReservationBean as the write destination, and handle the processing Write to the defined variable of ReservationBean as output in ReservationBean. Here, “reservation reservation number” indicates a reservation number, and “reservation reservation date” indicates a reservation date.

Step S117:
Next, when the business process execution engine 21 writes the result of the business process processing to the ReservationBean arranged in the interface container ServiceSession, the business process wrapper 26 uses the interface and data format for the ReservationBean arranged in the interface container ServiceSession. Perform the conversion process.
Here, the business process wrapper 26 includes “reservation reservation number”, “reservation applicant name”, “reservation employee name”, “reservation employee name”, which are search result data described in the ReservationBean arranged in the interface container ServiceSession. The interface of “reservation reservation date” and “reservation departure date” and the conversion of the data format are performed.
That is, the business process wrapper 26 converts the ReservationBean interface and data format from the format used in the business process execution engine 21 to the format used in the servlet 24B.

Step S118:
The service adapter 25 reads the process identification information “1” added as the process identification information from the ReservationBean converted by the business process wrapper 26 in the interface and data format.
Then, the service adapter 25 delegates the business process process to the servlet 24B having the process identification information that matches the read process identification information “1” via the ReservationBean.

Step S119:
The servlet 24 </ b> B includes “reservation reservation number”, “reservation applicant name”, “reservation employee name”, “reservation reservation date”, and “reservation departure date”, which are search result data from the ReservationBean received from the service adapter 25. ”Is extracted, and the extracted“ reservation reservation number ”,“ reservation applicant name ”,“ reservation employee name ”,“ reservation reservation date ”, and“ reservation departure date ”are output to the JSP 23.

Step S120:
When the JSP 23 is supplied with a “reservation reservation number”, “reservation applicant name”, “reservation employee name”, “reservation reservation date”, and “reservation departure date”, the data supplied from these servlets 24B is stored. A screen (page) to be displayed is configured, and the configured screen is transmitted to the client.
Then, when the screen is supplied from the web server 2, the client displays this screen on the display device and notifies the user of the search result via the display device.
Further, the JSP 23 executes a servlet 24A for a process to be processed next in the business process “search for a reservation basic”, that is, a process “search for deposit status” of the process identification information “2”.

Next, the operation of the created business process / business rule execution system using the program generated by the program generation apparatus according to the present embodiment will be described using FIG. 1 and FIG. FIG. 6 is a sequence diagram showing the operation of the created business process / business rule execution system when processing a process to which the rule identification information of the business process definition file 301 is added.
Step S211:
For example, after the processing of the business process shown in FIG. 5, as the execution of the business rule processing of FIG. 6, in the description of the business process definition body file 301, Processing is shown.
Therefore, the JSP 23 reads the servlet file 102 corresponding to the process identification number “2” from the server storage unit 3 in the order of the combination of business processes, instantiates it, and executes the servlet 24A.

Then, the servlet 24A outputs an instruction to the JSP 23 to generate a screen for inputting “total amount of reserved sales” and “total amount of reserved deposit” as a business rule process of “search for deposit status”. .
As a result, the JSP 23 generates a screen for inputting “reserved sales amount” and “reserved deposit amount” and outputs the screen to the client.
The client displays the screen supplied from the web server 2 on the display device.
Then, the user inputs the amount corresponding to the reservation in the input fields of “total reservation sales amount” and “total reservation deposit amount” displayed.
As a result, the client transmits a JSP file including numerical values of “reserved sales amount” and “reserved deposit amount” as data to the web server 2.

Step S212:
The JSP 23 extracts “reserved sales amount” and “reserved deposit amount” from the JSP file input from the client, and extracts the extracted “reserved sale amount” and “reserved deposit amount” as process identification information. Output to “2” servlet 24B.
Further, the web server 2 reads the business rule wrapper file 105 corresponding to the process identification information “2” from the server storage unit 3 and instantiates the read file to execute the business rule wrapper 27. The service adapter 25 is already activated when the servlet 24B having the process identification information “1” is activated.

Step S213:
The servlet 24A activates the bean object PaymentStatusBean of the program for inputting and outputting data, and the process identification information “2” corresponding to its own process, the “reserved sales amount” and the “reserved deposit amount” of the data, The rule identification information is substituted into the activated PaymentStatusBean.
That is, the servlet 24A activates the PaymentStatusBean for delegating the business rule processing using its own data “total reserved sales amount” and “total reserved deposit amount” to the business rule execution engine 22, and performs the processing. “Total reservation sales amount” and “total reservation deposit amount”, which are data necessary for delegation, are substituted into input variables of PaymentStatusBean.

Step S214:
When the Payment Status Bean is activated, the service adapter 25 extracts the process identification information “2” from the activated Payment Status Bean, and the delegation destination information indicating the delegation destination of the process indicated by the extracted process identification information “2”. Is detected from the correspondence table set in itself.
Then, since the delegation destination for the process identification information “2” in the correspondence table set in the service adapter 25 is the business rule execution engine 22, the service adapter 25 delegates the process for the PaymentStatusBean to the business rule wrapper 27.
That is, the service adapter 25 performs control to delegate the process of the process identification information “2” from the servlet 24 </ b> A to the business rule execution engine 22 via the business rule wrapper 27.
Here, the service adapter 25 has the same process identification information as the process identification information added to the ReservationBean, that is, the business rule execution engine 22 via the business rule wrapper 27 to which the process identification information “2” is added. Control to delegate to.

Step S215:
Next, the business rule wrapper 27 extracts process identification information from the PaymentStatusBean.
Then, the business rule wrapper 27 determines whether or not the extracted process identification information matches the process identification information set for itself.
Here, when the process identification information matches, the business rule wrapper 27 converts the interface and data format in the data of “reserved sales amount total” and “reserved payment amount total” described in the Payment StatusBean.
Further, the business rule wrapper 27 performs a process of placing the converted ReservationBean in the KSession that is an interface container of the business rule execution engine 22.
Through the processing described above, the business rule wrapper 27 converts the interface and data format corresponding to the servlet 24A in the Payment StatusBean arranged in the interface container into the interface and data format in the data input / output of the business rule execution engine 22. . The business rule wrapper 27 adds a rule processing ID as identification information to the ReservationBean whose format has been converted.

Step S216:
Next, the business rule execution engine 22 reads the rule identification information described in the Payment StatusBean in the interface container KSession, and the data of “total reservation sales amount” and “total reservation payment amount”.
Further, the business rule execution engine 22 reads the business rule definition body file 302 corresponding to the rule identification information from the business rule definition body file storage unit 200.
Then, the business rule execution engine 22 executes the process of the business rule having the process identification number “2” according to the description of the read business rule definition body file 302.
As described above, the “reserved sales amount total” and “reserved payment amount total” of the data used for the “search for payment status” process of the process with the process identification number “2” are sent to the business rule execution engine 22. Supplied from the servlet 24A via the interface container KSession.

Next, the business rule execution engine 22 extracts the added rule identification information from the description of PaymentsStatusBean arranged in the KSession of the interface container.
Then, the business rule execution engine 22 searches and reads the business rule definition body file 302 corresponding to the extracted rule identification information from the business rule definition body file storage unit 200.
Next, in accordance with the description of the business rule definition file 302 read out from the business rule definition file storage unit 200, the business rule execution engine 22 performs the data “total reserved sales amount” and “total reserved deposit amount” delegated from the servlet 24A. ”Is used to execute business rule processing.

At this time, the business rule execution engine 22 compares the supplied “reserved sales amount” and the “reserved deposit amount” according to the conditional expression described in the business rule definition file 302, so that the receipt status is “not yet received”. Processing for determining whether the deposit is “partial deposit”, “paid”, or “exceeded deposit” is performed.
Then, the business rule execution engine 22 uses the same rule identification as the file name of the business rule definition file 302 that has been placed in the interface container KSession and has received the payment status selected as a result of the determination process. Write to variables output by PaymentsStatusBean with information.

Step S217:
Next, when the business rule execution engine 22 writes the result of the business rule processing to the PaymentsBean arranged in the interface container KSession, the business rule wrapper 27 reads the rule processing from the PaymentsBean arranged in the interface container KSession. Processing to convert the PaymentsBean selected by the ID into an interface and data format is performed.
Here, the business rule wrapper 27 converts the “reservation payment status” interface and data format described in the PaymentsBean arranged in the interface container KSession.
That is, the business rule wrapper 27 converts the PaymentsBean interface and data format from the format used in the business rule execution engine 22 to the format used in the servlet 24A.

Step S218:
The service adapter 25 reads the process identification information “2” added as the process identification information from the PaymentsBean in which the reservation payment status is written by the business rule wrapper 27.
Then, the service adapter 25 delegates the business process process to the servlet 24A having the process identification information that matches the read process identification information “2” via the PaymentsBean.

Step S219:
The servlet 24A extracts the payment status data, which is the result of the determination process, from the PaymentsBean delegated by the service adapter 25, and outputs the extracted payment status data to the JSP 23.

Step S220:
When the deposit status data is supplied, the JSP 23 configures a screen (page) on which the deposit status data supplied from the servlet 24A is displayed, and transmits the configured screen to the client.
Then, when the screen is supplied from the web server 2, the client displays this screen on the display device and displays the search result of the deposit process to the user.
Further, the JSP 23 executes a servlet 24B of a process “select reservation basic” of the process identification information “3”, which is processed next in the business process “search for reservation basic”.

As described above, the business process / business rule execution system according to the present embodiment uses the correspondence table indicating the correspondence between the process identification information and the engine identification information indicating the delegation destination of the process in correspondence with the presence or absence of the rule identification information. The service adapter 25 that distributes the process is provided to either the business process execution engine 21 or the business rule execution engine 22.
For this reason, according to the business process / business rule execution system of the present embodiment, the business rule execution engine is called through the business process execution engine as in the prior art, and the process in the business process execution engine due to a load such as this call processing. Decreasing the processing efficiency can be prevented.

  In the embodiment described above, one service adapter 25 is generated for all servlets 24 operating in the business process / business rule execution system, and the process identification information described in the correspondence table and the process The bean generated by the servlet 24 is distributed to either the business process execution engine 21 or the business rule execution engine 22 based on the engine identification information indicating the process transfer destination.

However, the service adapter 25 may be generated for each process.
That is, the program generation device 1 sets the service adapter file 103 for each process as a program file of the service adapter 25 in which whether to delegate the process of the process to either the business process execution engine 21 or the business rule execution engine 22 is set. To generate.
That is, the program generation device 1 corresponds to a process to which rule identification information is not added, and corresponds to a service adapter 25 that outputs an input bean to the business process execution engine 21 and a process to which rule identification information is added. Then, the service adapter file 103, which is each program file with the service adapter 25 that outputs the input bean to the business rule execution engine 22, is generated for each process depending on whether or not rule identification information is added.
Then, the program generation device 1 associates the service adapter file 103 with the process identification information of this process and copies it to the server storage unit 3.

Further, when operating the business process / business rule execution system, when the servlet 24 is activated, the web server 2 corresponds to the process identification information for specifying the process to be processed by the servlet 24, and the service adapter file 103 is stored in the server. The service adapter 25 is activated by reading from the storage unit 3 and instantiating it.
The servlet 24 generates a bean (ReservationBean or PaymentsBean) for the service adapter 25 having the same process identification information, and delegates the processing.
The service adapter 25 sends a bean identical to its own process identification information to a wrapper (business process wrapper 26 or business) corresponding to the execution engine interface container (ServiceSession or KSession) set in advance as a delegation destination. Place via rule wrapper 27).

That is, if the input bean is ReservationBean, that is, if it is a bean generated by the servlet 24B corresponding to a process to which no rule identification information is added, the service adapter 25 corresponds to the business process wrapper corresponding to the business process execution engine 21. To 26, the process for the input ReservationBean is delegated.
On the other hand, if the input bean is PaymentsBean, that is, the service adapter 25 is output from the servlet 24A generated corresponding to the process to which the rule identification information is added, the business rule execution engine 22 The process for the input PaymentsBean is delegated to the business rule wrapper 27 corresponding to.
With the configuration described above, according to the present embodiment, when the program of the service adapter 25 is changed by changing the process, it is only necessary to change the program of the service adapter 25 corresponding to the changed process. Management is simplified.

In this embodiment, when information is to be inherited between different servlets 24, that is, between a plurality of screens, information to be inherited is stored in the session scope, and the session scope is displayed on another screen different from the stored screen. It is possible to read and use information that is desired to be inherited from.
FIG. 7 is a diagram illustrating a description example of a table of the business process definition file 301 when there is information that is desired to inherit the same information on a plurality of screens.

For example, when [SS] SET and a character string are described as a supplement to the business process definition table described in the business process definition file 301, the servlet 24 operates on the operation target path on this line in the table. The data indicated by “Reservation: 1” described in the column of “Reservation: 1”, that is, the entity name “Reservation: 1 / reservationReservationStored” and the value of the variable “Reservation: 1 / reservationReservationReference” Is stored in the session scope.
Further, the character string “[FW] STA00004_001” set in the supplementary column indicates the identification information of the process to be executed next after the currently executing process is executed. Accordingly, in the upper table of FIG. 7, the process “search reservation basic” in the lower table, which is “STA00040_001”, is executed after the process “select reservation basic” of the number “2”. It will be. In this process “search for reservation basic”, the value of the variable stored in the session scope is used.
The character string “[SS] DEL” is stored in another servlet 24 before the current one, and indicates that information to be taken over is stored in the current session scope.

In addition to this, when the character string indicating the storage of data in the session scope is [SS] SET indicating the setting of data in the session scope, the servlet 24 sets the line in which the character string [SS] SET is set. Is generated by the program generation device 1 so as to include a function for storing the data of the name of the entity included in the operation target path described in the operation target path field in the session scope (described later). .
When the character string indicating the storage of data in the session scope is [SS] DEL indicating the deletion of the data stored in the session scope, the servlet 24 enters the session scope in another servlet 24 before the current time. It is generated by the program generation device 1 so as to include a function of deleting the information of the name of the entity name included in the stored operation target path (described later).

  With the configuration described above, according to the present embodiment, when the servlet is not continuous and the information to be taken over in the request scope cannot be stored, or when the setting is such that the cookie cannot be used, it has already been described. Further, by using a general session management function (PHP: Hypertext Preprocessor 4.0) and adding a session ID as a session variable, it is possible to easily take over data between servlets that are executed discontinuously.

<Program generation used in business process / business rule execution system>
A method for generating a program used in a business process / business rule execution system according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 8 shows a program generation apparatus that generates a program used in a business process / business rule execution system (for example, implemented in JAVA (registered trademark) in this embodiment) according to an embodiment of the present invention. It is a schematic block diagram which shows the example of a structure.
In FIG. 8, a program generation apparatus 1 includes a business process definition analysis unit 11, a business process definition file conversion unit 12, a servlet generation unit 13, a service adapter generation unit 14, a business process. A wrapper (Business Process Wrapper) generation unit 15, a business rules wrapper (Business Rules Wrapper) generation unit 16, a business rule definition file analysis unit 17, a business rule definition file deployment unit 18, and a storage unit 19 are provided.

Next, FIG. 9 is a diagram illustrating an example of a table in the business process definition file 301 in which program generation information used when generating a program used in the business process / business rule execution system is described. The business process definition file 301 is created by being described by a worker who creates a business process / business rule execution system for each business process.
This FIG. 9 is described by the specification which describes the item shown below in a table format, for example, Excel (registered trademark).
The business process is composed of a plurality of processes or one process as shown in FIG.

As a business process definition of the table of FIG.
Item A: Process identification information that uniquely identifies a process Item B: Process name that is the name of a process identified by the process identification information Item C: Process processing type or item operation type Item D: Process is an operation target Operation item information indicating the table name and items in the table Item E: Operation target that is detailed information of the table to be processed in the process Item F: When the process is a process of a business rule, this business rule must be unique It consists of definitions in each item of rule identification information to be identified.

In the present embodiment, the program generation information is the process identification information, process name, item type, operation item information (attribute name), operation target, rule described in the table in the business process definition file 301 shown in FIG. It has identification information (if it exists).
For example, in the table in the business process definition file 301 shown in FIG. 9, the process identification information (item A) is “1” described in the number column. The process name (item B) is “search reservation basic” described in the process name column. The item type (item C) is “SEARCH”, which is the type of process processing described in the item type column, and “Search” or “Output”, which is item operation information in the process processing. The operation item information (item D) is described in the column of label name (entity name) / label name (attribute name) and entity name / attribute name. (Reservation reservation number), “reservation applicant name”, “reservation departure date”, “reservation employee name”, and the like (attribute name), entity name “Reservation”, and attribute name “ reservationReservationReferenceld ”,“ reservationReservationApplicantName ”, etc.

The detailed information (item E) is “Reservation” described in the operation target path column. The rule identification information (item F) is “d_rule_001” which is the rule identification information described in the column of the external rule in the row of the process identification information “2”.
Although not shown in the figure, as operation information in the process, it is described as a mark indicating whether or not there is an input in the input (Input) column, and whether or not the information can be transferred to any one of the transcription (Cascade) columns. Is described as a mark indicating that input of information of the corresponding label (attribute name) is optional, and a corresponding label (Multiple) is displayed in the corresponding ( It is described as a mark indicating whether or not the number of information of (attribute name) is more than one, and when searching for the corresponding label (attribute name) in the comparison (Operetor) field, complete match (=) or partial match (like ) Is described.

Returning to FIG. 8, the business process definition analysis unit 11 reads the business process definition file 301 as a table shown in FIG. 9 from an external device or an external storage unit by a user operation, and writes and stores it in the storage unit 19. .
Further, the business process definition analyzing unit 11 sequentially reads out the business process definition body file 301 from the storage unit 19, and for each process constituting the business process, process identification information, process name, item type, Each of the operation item information, operation information, operation target, and rule identification information is extracted and read.
The business process definition analysis unit 11 adds process identification information of the corresponding process to the read program generation information for each process, and temporarily writes and stores the process identification information in the storage unit 19 for each process.
Further, the business process definition analyzing unit 11 displays the process name when the input data from the user is not described in the item in the table of the business process definition file 301 in which the input data is set in advance. If the item type, attribute name, etc. are not descriptions used in the business process execution engine and business rule execution engine, an output unit such as a display unit that does not show that the description of the business process definition file 301 is incomplete To the operator via

  The business process definition file conversion unit 12 has a format format that is set in advance according to the item type, operation item information, and operation information in the program generation information of each process constituting the business process read from the storage unit 19, that is, a business process A business process definition body (XML) file 101 in a format that can be decoded by the execution engine 21 (FIG. 1) is generated. Here, the business process definition file conversion unit 12 determines whether or not the rule identification information is added, and the business process definition file (XML) file 101 is applied only to the process to which the rule identification information is not added. Is generated.

For example, the business process definition file conversion unit 12 generates a business process definition file (XML) file 101 for each process in which each item of program generation information is described in an XML (Extensible Markup Language) format.
At this time, the business process definition file conversion unit 12 reads the business process definition file template from the business process definition file template storage area in the storage unit 19.
In this business process definition file template storage area, the business process execution engine 21 is stored in units of processes in the business process definition file shown in FIG. 9 for each combination of process identification information, item type, operation item information, and operation information. A business process definition file template in a format that can be decoded is stored.
Then, the business process definition file conversion unit 12 adds the process identification information, item type, operation item information, and operation information read from the storage unit 19 to the read business process definition file template, for each process. The business process definition body (XML) file 101 is generated.

The servlet generation unit 13 uses the process identification information, the item type, and the operation item information in the program generation information of each process constituting the business process read from the storage unit 19, and the servlet corresponding to the description of the format format set in advance. A servlet file 102 in which a program is described is generated. The servlet file 102 is a file in which a source code of a program of the servlet 24 that is executed on a web server and constructs a web page in cooperation with a JSP is described (described later).
At this time, the servlet generation unit 13 stores the process identification information, item type, and operation item read from the storage unit 19 in the servlet template stored for each item type in the servlet template storage area of the storage unit 19. Information is added, a program for each process is generated, and a servlet file 102 in which these programs are described is output.

The service adapter generation unit 14 is a program that indicates which of the business process execution engine 21 and the business rule execution engine 22 is the delegation destination of each process for each process of the business process definition file 301.
That is, the service adapter generation unit 14 includes, for each process identification information, a correspondence table indicating whether the process indicated by the process identification information is delegated to either the business process execution engine 21 or the business rule execution engine 22. When the identification information is input, the correspondence table is referred to generate a program for delegating the process of the process indicated by the process identification information to either the business process execution engine 21 or the business rule execution engine 22. The service adapter file 103 in which the program is described is output.

The business process wrapper generation unit 15 generates a program of the business process wrapper 26 corresponding to the servlet 24 (for example, the servlet 24B) generated from the program generation information of the process that does not include the rule identification information, and the source of this program A business process wrapper file 104 in which the code is described is output.
As described above, the business process wrapper 26 corresponds to the interface format and data format of the business process execution engine 21 with the interface format and data format of a bean (ReservationBean) used by the servlet 24 to delegate data. And convert to the interface format of the ReservationBean in the interface container ServiceSession and the format of the data corresponding to the format of the interface of the servlet 24 and the format of the data. Is a program that performs a process of delegating to the service adapter 25.

That is, in the business process wrapper file 104, when the servlet 24 delegates process processing to the business process execution engine 21, the format of the ReservationBean interface (output) and the data format of the data output by the servlet 24 Is converted into a format and data format corresponding to the interface (input) of the business process execution engine 21, and when the business process execution engine 21 outputs the processing result of the process to the servlet, the interface that the business process execution engine outputs A program for performing processing for converting the (output) format and the data format into the interface (input) format and data format of the servlet 24 is described.
The business process wrapper generation unit 15 generates the program of the business process wrapper 26 for each process because the type and number of data input / output for each process are different, that is, the interface and data are different for each process. Here, the data format indicates a data type (variable) such as byte, short, int, or long.

The business rule wrapper generation unit 16 generates a business rule wrapper 27 program corresponding to the servlet 24 (for example, the servlet 24A) generated from the program generation information of the process including the rule identification information, and the source of this program The business rule wrapper file 105 in which the code is described is output.
As described above, the business rule wrapper 27 corresponds to the interface format and data format of the business rule execution engine 22 with the interface format and data format of the bean (PaymentStatusBean) used by the servlet 24 to delegate data. The conversion is performed and placed in the converted interface container KSession. Conversely, the PaymentStatusBean interface format and data format in the interface container KSession are converted in accordance with the interface format and data format of the servlet 24, and processed. Is a program that performs a process of delegating to the service adapter 25.

That is, in the business rule wrapper file 105, when the servlet 24 delegates process processing to the business rule execution engine 22, an interface (output) for outputting data and the format of the data are displayed in the business rule. When the business rule execution engine 22 outputs the processing result to the servlet, the interface (output) and data format output by the business rule execution engine 22 are converted into the interface (input) and data format of the execution engine 22. A program is described for converting the above into a servlet interface (input) and data format.
Similarly to the business process wrapper generation unit 15, the business rule wrapper generation unit 16 has different types and number of data input / output for each process, that is, the interface is different for each process. Generate a program for each process.

Each of the servlet file 102, the service adapter file 103, the business process wrapper file 104, and the business rule wrapper file 105 described above is a file in which the source code of the program is described, for example, a JAVA (registered trademark) file.
Further, the program generation device 1 temporarily writes each of the created servlet file 102, service adapter file 103, business process wrapper file 104, and business rule wrapper file 105 in the storage unit 19, and stores them later on the web server. It is mounted on the web server 2 by writing and storing it in the server storage unit 3 of FIG.

The business rule definition file analysis unit 17 reads the business rule definition file 302 from an external device or an external storage unit, and writes and stores it in the storage unit 19 by a user operation.
In addition, the business rule definition file analysis unit 17 reads the business rule definition file 302 from the storage unit 19 and extracts rule identification information described in the business rule definition file 302.
The business rule definition file analysis unit 17 stores the business rule definition file 302 having the same file name as the rule identification information extracted from the business process definition file 301 in the storage unit 19. It is detected whether or not it exists in it (consistency check is performed). In the present embodiment, the same character string is used for the rule identification information and the file name of the business rule definition file corresponding to this identification information.
Here, the business rule definition file analysis unit 17 stores the business rule definition file having the same file name as the rule identification information extracted from the business process definition file 301 stored in the storage unit 19. If it does not exist in 302, an error message indicating that consistency cannot be obtained is output from an output unit such as a display device to notify the user.

The business rule definition file analysis unit 17 has a business rule definition file having the same file name as the rule identification information extracted from the business process definition file 301 in the business rule definition file 302 stored in the storage unit 19. In such a case, a message indicating that consistency has been achieved is notified to the user from an output unit such as a display device.
In addition, when the business process definition file 301 and the business rule definition file 302 can be matched, the business rule definition file deployment unit 18 reads the consistent business rule definition file 302 from the storage unit 19. Then, the business rule execution engine 22 writes and stores it in the business rule definition file storage unit 200 to be read (copying the business rule definition file 302).

According to the present embodiment with the above-described configuration, the process of the servlet 24 is added to either the business process execution engine 21 or the business rule execution engine 22 depending on whether or not rule identification information is added to each of the processes constituting the business process. The program of the service adapter 25 that sorts whether to execute the process can be generated in conformity with the description of the business process definition file 301.
For this reason, according to the present embodiment, in the execution of business process processing in the business process execution engine 21, there is no processing that places an unnecessary load such as call processing in the business rule execution engine 22 as in the prior art. A program implemented in a business process / business rule execution system capable of improving the efficiency of processing operation can be easily generated.

  In addition, according to the present embodiment, in order to automatically generate a service adapter having a configuration in which business process processing is distributed to either a business process execution system or a business rule execution system depending on the content of the process, for each process. Even if the business process execution engine is changed, the development man-hour of the worker in generating a program to be implemented in the business process / business rule execution system is not increased as in the past.

In the present embodiment, the service adapter generation unit 14 generates one service adapter for all the processes used in the business process / business rule execution system. That is, in the present embodiment, the service adapter generation unit 14 refers to the correspondence table indicating the correspondence between the process identification information and the execution engine that is the delegation destination of the process indicated by the process identification information. A service adapter that delegates to the execution engine corresponding to the process identification information is generated.
However, the service adapter generation unit 14 may be configured to generate one service adapter 25 for each process. In this case, the service adapter 25 delegates the process of the process corresponding to the process identification information set in itself to the delegation destination set in itself (either the business process execution engine 21 or the business rule execution engine 22). It has a function to perform processing.

  The program generation apparatus 1 according to the present embodiment uses a computer such as a server or a personal computer, and includes a business process definition analysis unit 11, a business process definition file conversion unit 12, a servlet generation unit 13, a service adapter generation unit 14, a business Each of the process wrapper generation unit 15, the business rule wrapper generation unit 16, the business rule definition file analysis unit 17, and the business rule definition file deployment unit 18 may be configured to operate as a module on a program.

Next, processing for generating a program used in the business process / business rule execution system by the program generation apparatus 1 according to the present embodiment will be described with reference to FIG. FIG. 10 is a sequence diagram showing an operation of generating a program used in the business process / business rule execution system by the program generation apparatus 1 of the present embodiment.
Step S1:
The business process definition analysis unit 11 receives the process identification information, process name, item type, operation item information, operation information, operation target, rule identification information as program generation information from the input table-format business process definition file 301. Are extracted and read out as program generation information, and are written and stored in the storage unit 19 corresponding to the process identification information for each process.

Next, the servlet generation unit 13 sequentially reads out the program generation information for each process from the storage unit 19, and reads out the program template corresponding to the item type of the process from the servlet template storage area in the program generation information.
Then, the servlet generation unit 13 generates the program source code of the servlet 24 by adding each data of the program generation information including the process identification information to the read template, and the source code of the servlet 24 is described. Generated servlet file 102 is generated.
As a result, the servlet generation unit 13 generates a program of the servlet 24 that causes the business process execution engine 21 or the business rule execution engine 22 to execute the process described in each process of the business process definition file 301. The source code of the servlet 24 program is written and stored in the storage unit 19 as the servlet file 102 in association with the process identification information.

Step S2:
The business process definition file conversion unit 12 determines whether or not rule identification information is added for each process stored in the storage unit 19.
And the business process definition body file conversion part 12 reads sequentially the program production | generation information corresponding to the process to which rule identification information is not added.
The business process definition file conversion unit 12 reads a template of the business process definition file stored in the storage unit 19. The template of the business process definition file is a source for generating a business process definition file in a format that can be decoded by the business process execution engine 21.
When the program generation information is read, the business process definition file conversion unit 12 adds each piece of data of the read program generation information to the template of the business process definition file, so that the business process execution engine 21 can decode the business process. A definition body (XML) file 101 is generated, and written and stored in the storage unit 19 in association with the process identification information.

Step S3:
The service adapter generation unit 14 sequentially reads out the program generation information stored in the storage unit 19 for each process, and determines whether or not rule identification information is added.
Then, the service adapter generation unit 14 uses the business process execution engine 21 as the delegation destination of the servlet 24 process to which rule identification information is not added, and executes the business rule as the delegation destination of the process of the servlet 24 to which rule identification information is added. The engine 22 is determined.

As a result, the service adapter generation unit 14 adds a correspondence table in which process identification information is associated with delegation destination information whose delegation destination is either the business process execution engine 21 or the business rule execution engine 22. A service adapter 25 for delegating the processing of the servlet 24 to the execution engine described in the delegation destination information corresponding to the process identification information is generated, and a service adapter file 103 in which the source code of the program of the service adapter 25 is described is created. Output.
Further, the service adapter generation unit 14 writes the generated service adapter file 103 into the storage unit 19 and stores it.

Step S4:
The business process wrapper generation unit 15 sequentially reads out the program generation information stored in the storage unit 19 for each process, and determines whether or not rule identification information is added.
When the rule identification information is not added as a result of the determination, the business process wrapper generation unit 15 uses a bean that the servlet 24 uses to input / output data, and an interface container that the business process execution engine 22 uses to input / output data. When arranged in the Service Session, a business process wrapper 26 is generated that matches the format of the interface and data with the format of the output side of the servlet 24 and the business process execution engine 22 to the format of the input side.
The business process wrapper generation unit 15 writes and stores the generated business process wrapper file 104 of the business process wrapper 26 in the storage unit 19.

Step S5:
The business rule wrapper generation unit 16 sequentially reads out the program generation information stored in the storage unit 19 for each process, and determines whether or not rule identification information is added.
When the rule identification information is added as a result of the determination, the business rule wrapper generation unit 16 uses the PaymentStatusBean that the servlet 24 uses for data input / output, and the interface container KSession that the business rule execution engine uses for data input / output. When it is arranged inside, a business rule wrapper 27 is generated that matches the format of the interface and data with the format of the output side of the servlet 24 and the business rule execution engine 22 to the format of the input side.
The business rule wrapper generation unit 16 writes and stores the generated business rule wrapper file 105 of the business rule wrapper 27 in the storage unit 19.

Step S6:
The business rule definition file analysis unit 17 detects the program generation information including the rule identification information from the program generation information of all processes stored in the storage unit 19, and extracts the rule identification information from the program generation information.
Then, the business rule definition file analysis unit 17 determines whether the business rule definition file 302 having the same file name as the extracted rule identification information exists in the business rule definition file 302 stored in the storage unit 19. By determining whether or not the process having the rule identification information in the business process definition file 301 and the business rule definition file 302 are consistent, a consistency check is performed.

In the check result, when all of the extracted rule identification information is associated with the business rule definition file 302 with the same file name, the business rule definition file analysis unit 17 and the business rule definition file 302 and the rule identification information And a control signal indicating that consistency is achieved is output to the business rule definition file deployment unit 18.
On the other hand, the business rule definition file analysis unit 17 includes rule identification information that is not associated with the file name of the business rule definition file 302 stored in the storage unit 19 in the rule identification information extracted from the program generation information. Is present, it is determined that the business rule definition file 302 and the rule identification information are not consistent.
Then, the business rule definition file analysis unit 17 outputs an error message indicating the process identification information of the process determined to be inconsistent from the output unit to notify the user.

  Next, when the business rule definition body file deployment unit 18 is supplied with a control signal indicating that consistency is obtained from the business rule definition body file analysis unit 17, the business rule definition body file 302 having consistency is provided. Is written and stored in the business rule definition file storage unit 200.

Next, FIG. 11 is a conceptual diagram showing various programs generated corresponding to a process to which no rule identification information is added, based on the program generation information extracted from the business process definition file 301.
As shown in FIG. 11, in the business process definition file 301, it corresponds to the process of the process identification information “1” to which no rule identification information is added (the process of the process identification information “3” is also the same). A business process definition body (XML) file 101 is generated in which the table description is in a format decipherable by the business process execution engine 21.
Similarly, similarly to the business process definition body (XML) file 101, the servlet file 102 is generated by the servlet generation unit 13 and the business process wrapper file 104 is generated by the business process wrapper generation unit 15 for each process.

FIG. 12 is a conceptual diagram showing various programs generated corresponding to the process to which the rule identification information is added based on the program generation information extracted from the business process definition file 301.
As shown in FIG. 12, in the business process definition file 301, the servlet file 102 is generated from the program generation information corresponding to the process of the process identification information “2” to which the rule identification information is added. 13, and the business process wrapper file 104 is generated for each process by the business process wrapper generation unit 15.
Further, as described above, the service adapter file 103 described in FIGS. 11 and 12 is stored in the storage unit 19 regardless of whether or not rule identification information is added. One is generated for all processes included in all of the business process definition file 302.

Next, FIG. 13 is a conceptual diagram showing various programs generated from a business process including processes of process identification information “1”, “2”, and “3”.
As described with reference to FIGS. 11 and 12, one servlet file 102 is generated for a process regardless of whether or not rule identification information is added. Therefore, since there are three processes in the business process definition file 301 for business processing in FIG. 13, three servlet files 102 are generated by the servlet generation unit 13 in the case of this business process definition file 301.
In addition, the business process definition body (XML) file 101 is generated only for a process to which rule identification information is not added. For this reason, in the business process definition file 301 of FIG. 13, there are two processes with no rule identification information, process identification information “1” and “3”. Two 101 are generated by the business process definition file conversion unit 12.

Further, the business process wrapper file 104 is generated only for a process to which rule identification information is not added. For this reason, in the business process definition file 301 of FIG. 13, there are two processes, process identification information “1” and “3”, to which no rule identification information is added. Two are generated by the process wrapper generation unit 15.
The business rule wrapper file 105 is generated only for the process to which the rule identification information is added. Therefore, in the business process definition file 301 of FIG. 13, the process to which the rule identification information is added is one of the process identification information “2”, and the business rule wrapper file 105 is a business rule wrapper generation unit. 16 generates one.

In the above-described various programs, when a process to which the same process identification information is added is duplicated in a plurality of business processes, only one program is generated for the process having the same process identification information.
That is, each of the business process definition file conversion unit 12, the servlet generation unit 13, the service adapter generation unit 14, the business process wrapper generation unit 15, and the business rule wrapper generation unit 16 has already been generated when a new program is generated. The process identification information of the program is compared with the process identification information of the program to be generated. If they do not match, the program is generated. On the other hand, if they match, the program is not generated.
Further, one service adapter file 103 is provided for all processes, that is, for the processes of the business process definition file 301 for all business processes input to the business process / business rule execution system of the present embodiment. 1 is generated by the service adapter generation unit 14.

  Further, the program for realizing the functions of the web server 2 in FIG. 1 and the web server 2 in FIG. 8 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into a computer system. The program generation process, the business process, and the business rule process may be managed by executing the program. Here, the “computer system” includes an OS and hardware such as peripheral devices.

Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case, and a program that holds a program for a certain period of time are also included. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes design and the like within a scope not departing from the gist of the present invention.
