  The program generation unit 110 of the Web application generation apparatus 100 uses the data model definition 104, which is an item used in the application, and the definition information of the input / output definition 107 of the application screen, and uses the value of the definition information as a parameter. The web application 160 is generated by reading the web service code and creating the stub code for the web application processing by applying the template to the source code necessary for generating the application. Then, the generated web application 160 is arranged on the web application server 170.

  The user terminal 140 is a terminal for performing workflow processing in the workflow system 1. The user terminal 140 includes two types of terminals: a user terminal 140a that is a mobile terminal and a user terminal 140b that is a PC.

  Note that the filter processing unit 125 of the workflow server 120 enables the user terminal 140 to access the workflow system 1 by returning the screen of the client application 150 or the Web application 160 to the user terminal 140.

  That is, the filter processing unit 125 causes the web application 160 of the web application server 170 to be accessed when access is received from the user terminal 140a, and exists at the user terminal 140b when access is received from the user terminal 140b. The client application 150 is accessed.

  Further, in order to make it possible to access the data of the workflow database 130 from the generated Web application 160 (in order to enable the workflow system 1 in FIG. 1), the server processing program conversion unit 101 performs workflow processing. The existing processing of the unit 123 is disclosed as a Web service, and the WS interface 124 is created.

  The details of each part (each function) in FIG. 3 will be described below.

<< Publication Process of Processing Function as Web Service >>
First, a process for publishing as a Web service so that an existing processing function (in the case of the workflow system 1, drafting, approval, etc.) existing in the workflow processing unit 123 of the workflow server 120 can be called from the Web application 160. Will be described.

  The server processing program conversion unit 101 converts the processing content of the source of the workflow processing unit 123 into the WS interface 124 so that the workflow processing unit 123 can be accessed from the outside via a Web service.

  FIG. 4 is a flowchart showing Web service conversion processing. 4 is performed by the server processing program conversion unit 101 of the Web application generation device 100.

  In step S <b> 201, the CPU 201 (server processing program conversion unit 101) of the Web application generation apparatus 100 acquires a source code file for performing workflow processing, which is described in the workflow processing unit 123 of the workflow server 120. The developer specifies the source code file that is performing the workflow process. For example, the source code file 301 illustrated in FIG.

  Next, in S202, the CPU 201 (server processing program conversion unit 101) of the Web application generation apparatus 100 performs syntax analysis of the source code file designated by the developer.

  Next, in S203, the CPU 201 (server processing program conversion unit 101) of the Web application generation apparatus 100 accepts a copy of the source code acquired in S201, and adds an annotation description for publishing the Web service to the copied source code. Accept (303, 304, 305 in FIG. 5B).

  FIG. 5 shows an example of source code conversion. A source code file 301 in FIG. 5A is a source code before conversion. In this example, the Java (registered trademark) language is taken as an example, but conversion processing is possible in any language. The source code file 302 in FIG. 5B is a source code in which annotations are added to the source code file 301 as a description for Java (registered trademark) language to be published as a Web service. Annotations are shown at 304 and 305 in FIG. Reference numeral 303 denotes an import declaration for using an annotation.

  Next, in S204, the CPU 201 (server processing program conversion unit 101) of the Web application generation apparatus 100 generates a Web service processing code for the converted source code, and in S205, what Web service exists, A WSDL (Web Services Description Language) is generated that describes what operations exist in the file and what arguments should be passed to the operation. FIG. 20 illustrates WSDL. Note that the Web service processing code and the WSDL can be generated by executing a command called WSGEN, for example.

  Finally, in S206, the CPU 201 (server processing program conversion unit 101) of the Web application generation apparatus 100 publishes the Web service processing code and WSDL so that the Web service can be accessed from the network. Note that the CPU 201 (server processing program conversion unit 101) of the Web application generation apparatus 100 sends the Web service processing code and WSDL to the WS interface 124 so that the published Web service processing code and WSDL are used. Deploy.

  With the above method, it is possible to construct a Web application that can be processed via the Web service interface without newly developing a process called from an existing client application.

  The workflow processing unit 123 configures an example of “processing information performed by the server in response to a request from the client application” according to the present invention.

  Further, S201 to 206 constitute an example of “Web service creation means for creating a Web service for enabling the processing information to be called from a Web application” according to the present invention.

<< Conversion processing of data structure information to data model definition >>
Next, a process of converting item data (data structure information 121) in the workflow server 120 required for configuring an application into a data structure (data model definition 104) on the Web application generation apparatus 100 side will be described.

  The data structure information acquisition unit 102 acquires the data structure information 121 that is stored in the workflow server 120 and that is the data structure of a case drafted in the workflow system 1.

  The data structure information acquisition unit 102 constitutes an example of “data structure information receiving means for receiving the data structure information stored in the design information storage means from the server” according to the present invention.

  Here, the data structure information 121 held by the workflow server 120 will be described.

  FIG. 6 is a diagram showing an example in which the data structure information 121 held by the workflow server 120 is displayed on the GUI editing screen. The data structure information 121 can be defined by using a GUI screen (data structure information GUI screen 400) as shown in FIG. The data itself is often managed as an XML file.

  FIG. 7 is a diagram showing an example in which the result of editing on the data structure information GUI screen 400 shown in FIG. 6 is saved as XML format data. Data structure information 121 edited on the data structure information GUI screen 400 is stored as an XML file 510.

  The item ID 401 is stored in the id attribute 511 of the schemaItem element of the XML file 510. The item name 402 is stored in the name attribute 512 of the schemaItem element of the XML file 510. The attribute 403 is stored in the type attribute 513 of the schemaItem element of the XML file 510. The number of characters 404 is stored in the length attribute 514 of the schemaItem element of the XML file 510. The decimal 405 is stored in the point attribute 515 of the schemaItem element of the XML file 01. Primary key information (not shown) is stored in the pkey attribute 516 of the schemaItem element of the XML file 510. The nullable information (not shown) is stored in the nullEnable attribute 517 of the schemaItem element of the XML file 510.

  In the data structure information GUI screen 400, the attribute 403 is displayed with a name such as a character or a numerical value, whereas in the XML file 510, it is stored with a value such as 00 or 01. This is because the data structure information GUI screen 400 changes the display depending on the value.

  The above is an example of the data structure information 121 held by the workflow server 120.

  The data structure information 121 constitutes an example of “data structure information that is data item information used in the client application” according to the present invention.

  The data model definition conversion unit 103 converts the data structure information 121 acquired by the data structure information acquisition unit 102 into the data model definition 104 with reference to the data structure information XML tag rule 610 and the data structure information value conversion rule 710. .

  FIG. 8 is an example of a table showing rules for converting the data structure information 121 managed in the XML format 510 shown in FIG. 7 into the definition of the data model definition 104 shown in 910 of FIG. The table in FIG. 8 is referred to as data structure information XML tag rule 610. The data structure information XML tag rule 610 is obtained from the value referred to by which XML tag in the data structure information 121 in FIG. 7 as the value defined in each data model definition 104 (for example, 911, 912, etc.) in FIG. Manage in a table format.

  The ID 600 manages each item type 601 by ID. The item type 601 indicates a value defined in the data model definition 104 (for example, 911, 912, etc.) shown in FIG. Further, the XML tag rule 602 indicates the location from which the value set in the data model definition 104 of the item type 601 is acquired by the position in the hierarchy of the data structure information 121 managed in the XML format of FIG.

  FIG. 11 is a diagram illustrating an example of the definition screen 910 for the data model definition 104 in the Web application generation apparatus 100. FIG. 11 shows an example in which the data structure information 121 (XML file 510) in FIG. 7 is converted into a data model definition 104 necessary for screen definition when building a Web application.

  The data model definition 104 constitutes an example of “a data model definition that is data item information used in a Web application” according to the present invention.

  Returning to the description of FIG. The item type 601 of ID 600 = 1 in FIG. 8 has a DM_ITEM_CODE value. This value indicates the item code 911 on the definition screen 910 of the data model definition 104. In FIG. 8, the XML tag rule 602 corresponding to this DM_ITEM_CODE is schemaDefinition.schema.schemaItem.id. This shows the rule that the value of the item code 911 of the data model definition 104 in FIG. 11 uses the value of id which is the attribute of the child element <schemItem> of the child element <schema> of <schemaDefinition> in FIG. ing.

  Similarly, DM_ITEM_NAME which is the value of the item type 601 of ID 600 = 2 in FIG. 8 indicates the name 912 of the definition screen 910 of the data model definition 104, and the value of the name 912 of the data model definition 104 in FIG. Shows a rule that the value of name that is an attribute of the child element <schemaItem> element of the child element <schema> of <schemaDefinition> in FIG. 7 is used. Thus, the relationship between the values of the data model definition 104 and the data structure information 121 is determined.

  That is, 511 in FIG. 11 has a value 511 in FIG. 7, 912 in FIG. 11 has a value 512 in FIG. 7, 913 in FIG. 11 has a value 517 in FIG. 7, and 914 in FIG. The value of 516 in FIG. 7, the value of 514 in FIG. 7 in 915 in FIG. 11, the value of 515 in FIG. 7 in 916 in FIG. 11, the value of 513 in FIG. It is converted and registered by the model definition conversion unit 103.

  The data model definition conversion unit 103 can perform the conversion on all the schemaItem information of the data structure information 121 in FIG. 7 to obtain the data model definition 104 displayed on the definition screen 910 in FIG. .

  When the value of the data structure information 121 is set to the value of the data model definition 104 in accordance with the rule of FIG. 8, further relationship definition may be necessary.

  For example, DM_ITEM_TYPE which is the value of the item type 601 of ID 600 = 5 in FIG. 8 indicates the data type 917 of the data model definition 104 in FIG. 11, and the value is a TEXT text type, a NUM numeric type, or the like. On the other hand, the corresponding value (type 513 in FIG. 7) in the data structure information 121 in FIG. 7 is a value such as 00 or 01.

  In such a case, it is necessary to define the conversion table shown in the example of FIG. FIG. 9 is a table of data structure information value conversion rules 710 that defines conversion rules when values in the data structure information 121 cannot be transferred to the data model definition 104. For example, a value of 00 in the XML value 701 in FIG. 9 and a value of the data model-data type 702 in the data model definition 104 is TEXT (TEXT text type in the display of 917 in FIG. 11).

  Thereby, the data structure information of the client application can be appropriately converted into a data model definition used when generating the Web application.

  FIG. 10 shows a flowchart in which the data model definition conversion unit 103 summarizes the above description and creates the data model definition 104 from the data structure information 121.

  In step S <b> 801, the CPU 201 (data model definition conversion unit 103) of the Web application generation apparatus 100 reads the data structure information 121 acquired from the workflow server 120 by the data structure information acquisition unit 102.

  In step S802, the CPU 201 (data model definition conversion unit 103) of the Web application generation apparatus 100 refers to the data structure information XML tag rule 610 illustrated in FIG. 8 and the data structure information value conversion rule 710 illustrated in FIG.

  In step S803, the CPU 201 (data model definition conversion unit 103) of the Web application generation apparatus 100 creates the data model definition 104 (or its file) from the data structure information 121 acquired in step S801 and each rule referenced in step S802. And stored in the external memory 211 of the Web application generating apparatus 100. The storage destination may be an internal hard disk (not shown) or an external hard disk.

  The processing from S801 to S803 is performed for each item existing in the acquired data structure information 121.

  This completes the description of the creation of the data model definition 104.

  The data model definition for storing the data structure information received from the data structure information receiving means as a data model definition that is information of data items used in the Web application according to the present invention by S801 to S803. An example of “storage means” is configured.

<< Conversion processing of layout information to input / output definition >>
Subsequently, processing for converting screen layout information (layout information 122) in the workflow server 120 necessary for configuring the application into screen layout information (input / output definition 107) on the Web application generation apparatus 100 side. Will be described.

  The layout information acquisition unit 105 acquires layout information 122 held by the workflow server 120.

  The layout information acquisition unit 105 constitutes an example of “layout information receiving means for receiving the layout information stored in the design information storage means from the server” according to the present invention.

  FIG. 12 is a diagram illustrating an example in which the layout information 122 held by the workflow server 120 is displayed on the GUI editing screen.

  When defining a screen layout for workflow processing, a GUI screen (layout information GUI screen 1000) as shown in FIG. 12 is often used. Also, the screen layout definition itself is often managed by an XML file.

  FIG. 13 is a diagram illustrating an example in which the result of editing on the layout information GUI screen 1000 is saved as XML format data. The layout information 122 edited on the layout information GUI screen 1000 is stored as layout information XML (file) 1100.

  For example, the order number field 1001 registered as a component in the layout information GUI screen 1000 of FIG. 12 is a tag element whose id, which is the attribute of the field element indicated by 1101, is ORDER_NO in the layout information XML 1100 of FIG. And its child elements.

  Similarly, the priority field 1002 in FIG. 12 is stored as a tag element whose id which is the attribute of the field element shown by 1102 in FIG. 13 is PRIORITY and its child elements.

  The layout information 122 constitutes an example of “layout information defining attribute information when the data structure information is used in the client application” according to the present invention. The data structure information 121, the layout information 122, and the workflow processing unit 123 constitute an example of the “design information storage unit” according to the present invention.

  The input / output definition conversion unit 106 converts the layout information 122 acquired by the layout information acquisition unit 105 into the input / output definition 107 with reference to the layout information XML tag rule 1210 and the layout information value conversion rule 1310.

  FIG. 14 is an example of a table showing the relationship between the layout information 122 and the input / output definition 107 defined in FIG. 17 of the Web application generation apparatus 100. The table in FIG. 14 is referred to as a layout information XML tag rule 1210. The layout information XML tag rule 1210 manages the relationship between the value defined in the input / output definition 107 defined in FIG. 17 and the value referred to by the tag of the layout information XML 1100 in a table format.

  ID 1200 manages each item type 1201 by ID. An item type 1201 indicates an item defined by the input / output definition 107 in FIG. The XML tag rule 1202 indicates the location in the hierarchy of the layout information 122 managed in the XML format in FIG. 13 where the value set in the input / output definition 107 managed by the item type 1201 is acquired.

  FIG. 17 is a diagram illustrating an example of a definition screen 1500 for the input / output definition 107 in the Web application generation apparatus 100. Note that the definition screen 1500 of the input / output definition 107 in FIG. 17 is an example in which the layout information XML 1100 (layout information 122) in FIG. 13 is displayed in a state converted to the input / output definition 107 of the Web application generation device 100. .

  The input / output definition 107 constitutes an example of “input / output definition that is definition information defining attribute information when used in the Web application” according to the present invention.

  Returning to the description of FIG. The item type 1201 of ID 1200 = 1 in FIG. 14 has a value of IO_ITEM_CODE. This value indicates the item code 1501 of the definition screen 1500 of the input / output definition 107 in FIG. In FIG. 14, the XML tag rule 1202 corresponding to this IO_ITEM_CODE is formDefinition.page.elements.field.id. This is because the value of the item code 1501 of the input / output definition 107 in FIG. 17 is the value of id which is the attribute of the child element <field> of the child element <element> of the child element <page> of <formDefinition> in FIG. It shows the rule to use.

  Similarly, IO_ITEM_NAME which is the value of the item type 1201 of ID 1200 = 2 in FIG. 14 indicates the name 1502 of the definition screen 1500 of the input / output definition 107 in FIG. 17 and the value of the name 1502 of the input / output definition 107 corresponding to this. Shows a rule that the value of the child element <label> of the child element <field> element of the child element <elements> of the child element <page> of the <formDefinition> in FIG. 13 is used. Thus, the relationship between the values of the layout information 122 and the input / output definition 107 is determined.

  When the value of the layout information 122 is set to the value of the input / output definition 107 in accordance with the rules of FIG. 14, further relationship definition may be required.

  For example, IO_ITEM_TYPE which is the value of the item type 1201 of ID 1200 = 3 in FIG. 14 indicates the item type 1503 of the input / output definition 107 in FIG. 17, and the values are O output, IO input / output, and the like. On the other hand, the corresponding value (value of the <editable> tag in FIG. 13) in the layout information 122 in FIG. 13 is true, false, or the like.

  Therefore, it is necessary to define this conversion, an example of which is shown in FIG. FIG. 15 is a table of the layout information value conversion rule 1310 that defines the relationship between the value of the layout information 122 (the value of the <editable> tag in FIG. 13) and the item type 1503 of the input / output definition 107. For example, in the layout information value conversion rule 1310, when the XML value 1301 is false, the item type 1302 is O, so the value of the <editable> tag in the XML of the layout information 122 in FIG. 13 is false. The value of the item type 1503 in the input / output definition 107 in FIG.

  As a result, the layout information of the client application can be appropriately converted into the input / output definition used when generating the Web application.

  FIG. 16 summarizes the above description, and the input / output definition conversion unit 106 creates the input / output definition 107 necessary for constructing the Web application from the layout information 122 on the client application side (native type). A flowchart is shown.

  In step S <b> 1401, the CPU 201 (input / output definition conversion unit 106) of the Web application generation apparatus 100 reads the layout information 122 acquired by the layout information acquisition unit 105 from the workflow server 120.

  In step S1402, the CPU 201 (input / output definition conversion unit 106) of the Web application generation apparatus 100 refers to the layout information XML tag rule 1210 illustrated in FIG. 14 and the layout information value conversion rule 1310 illustrated in FIG.

  In step S1403, the CPU 201 (input / output definition conversion unit 106) of the Web application generation apparatus 100 performs input / output definition from the layout information 122 based on the layout information XML tag rule 1210 in FIG. 14 and the layout information value conversion rule 1310 in FIG. 107 (or its file) is created and stored in the external memory 211 of the Web application generating apparatus 100. The storage destination may be an internal hard disk (not shown) or an external hard disk.

  The processing from S801 to S803 is performed for each layout information existing in the acquired layout information 122.

  This completes the description regarding the creation of the input / output definition 107.

  It should be noted that, according to S1401 to S1403, “the layout information received from the layout information receiving means” according to the present invention is stored as an input / output definition that is definition information defining attribute information when used in the Web application. An example of “input / output definition storage means” is configured.

<< Definition of layout adjustment and processing call by layout editor >>
The layout editor unit 108 reads the created input / output definition 107, accepts layout adjustment and definition placement for calling the process held by the workflow processing unit 123, and reflects the received result on the input / output definition 107. To do.

  FIG. 18 shows an example of the layout editor GUI screen 1600 of the layout editor unit 108. The layout editor unit 108 can read the contents of the input / output definition 107 and display it on the layout editor GUI screen 1600. Further, the layout editor unit 108 can perform editing operations such as changing the layout position, changing the label name, and deleting the arranged field items. Further, a new item can be added by arranging a new item in the layout editor GUI screen 1600 by the layout editor unit 108. In addition, the layout editor unit 108 can perform definition for invoking workflow processing for the operation button 1601 in FIG. This definition is described next.

  Next, processing for converting processing logic in the workflow server 120 required for configuring an application into processing logic on the Web application generation apparatus 100 side will be described.

  FIG. 19 shows an example of a process definition definition screen 1700. FIG. 19 is displayed in the layout editor GUI screen 1600 of FIG. 18 when defining the operation button indicated by the approval 1601 to call the process held by the workflow processing unit 123 via the WS interface 124. This is a definition screen. The processes held by the workflow processing unit 123 are processes such as drafting and approval in the case of the workflow system 1, but are not limited to drafting and approval processes when the client application side is not the workflow system 1. .

  The definition of this button is an item that can be managed as an action (action definition) in the item type 1503 on the definition screen 1500 for managing the input / output definition 107 in FIG. 17 (for example, FIG. 17). 1504).

  As an example, “ExecuteCaseWS # approveCase” is defined in the processing formula 1702 for the approval button 1701 in FIG. This is a definition for calling the approveCase method (305 in FIG. 5) of the ExcecuteCaseWS class (304 in FIG. 5) shown in the example of the source code file 302 in FIG.

  At the time of definition, the developer confirms the designated portions (1801 and 1802 in FIG. 20) of the WSDL 1800 in FIG. 20 generated in step S205 in FIG.

  That is, the processing formula 1702 in FIG. 19 describes which operation of which Web service is to be activated (ExecuteCaseWS is the Web service and approveCase is the operation name). The WSDL1800 1801 information and the approveCase of the processing formula 1702 can be defined by checking the WSDL1800 1802 information in FIG.

  By using the above method, processing can be performed via the Web service interface by setting processing information, which is a function that the server performs processing, to the operation button to be started without newly developing processing called from an existing client application. It is possible to construct a Web application that can be used.

  Note that 1702 in FIG. 19 constitutes an example of “definition information for enabling processing of existing processing information by the Web service created by the Web service creation unit” according to the present invention.

<< Web application generation processing >>
The program generation unit 110 reads the data model definition 104 and the input / output definition 107 and generates a Web application 160. FIG. 21 is a flowchart illustrating processing in which the program generation unit 110 reads the data model definition 104 and the input / output definition 107 and generates the Web application 160.

  In step S1901, the CPU 201 (program generation unit 110) of the Web application generation apparatus 100 reads the WSDL published by the workflow server 120.

  In step S <b> 1902, the CPU 201 (program generation unit 110) of the Web application generation apparatus 100 generates a stub code held in the Web application 160 in order to call the Web service of the workflow processing unit 123.

  In step S <b> 1903, the CPU 201 (program generation unit 110) of the Web application generation apparatus 100 reads the data model definition 104. In step S1904, the CPU 201 (program generation unit 110) of the Web application generation apparatus 100 reads the input / output definition 107.

  In step S <b> 1905, the CPU 201 (program generation unit 110) of the Web application generation apparatus 100 converts the read data model definition 104 and the input / output definition 107 into objects in the memory and imports them to perform definition analysis processing.

  In step S <b> 1906, the CPU 201 (program generation unit 110) of the Web application generation apparatus 100 reads the source code template held by the Web application generation apparatus 100 into the memory.

  In step S1907, the CPU 201 (program generation unit 110) of the Web application generation apparatus 100 defines the definition information extracted from the data model definition 104 read in step S1903 and the input / output definition 107 read in step S1904, and the source code read in step S1906. Perform source code generation using a template.

  In other words, the CPU 201 (program generation unit 110) of the Web application generation device 100 exists as a definition in the Web application generation device 100 in the processing from S1903 to S1907, FIG. 11 (data model definition 104), FIG. 107), based on the information set in FIG. 19 (action definition information defined in the input / output definition 107), the source code necessary to operate the Web application 160 is generated. Note that the Web application 160 generated by the source code can be accessed from the user terminal 140 to the workflow server 120.

  In this way, in the processing of FIG. 21, the stub code (S1902) and the web application source code (S1907) necessary for operating the web application 160 are generated.

  This completes the description of the flowchart for generating the Web application 160 of FIG.

  21. According to S1901 to 1907 in FIG. 21, according to the present invention, “to make it possible to process the existing processing information by the data model definition, the input / output definition, and the web service created by the web service creation unit. Using the definition information, an example of “generating means for generating a Web application” is configured.

<< Filter program generation processing >>
Subsequently, when the workflow server 120 is accessed from the user terminal 140, it is necessary to switch the program of the screen displayed on the display screen of the user terminal 140 according to the type of the terminal of the user terminal 140. A filter program generation process will be described.

  Note that when the user terminal 140 is a mobile terminal, it is impossible to access data to be processed in the workflow database 130 via a client application constructed on the premise of processing by a PC. Depending on the type of the terminal, a program generation process for switching the client application 150 or the Web application 160 to be operable is necessary.

  FIG. 22 is a table in which filter setting information 2010 necessary for distributing an application to be called by the filter processing unit 125 of the workflow server 120 when the user terminal 140 accesses the workflow server 120 is registered. It is an example.

  According to the filter setting information 2010, when the workflow server 120 is accessed from a PC, the client application 150 is called, or when accessed from a mobile terminal, the user application 140 is called. Depending on the type of application, the application to be called can be switched.

  The filter setting information 2010 in FIG. 22 manages the URL for accessing the processing screen of the workflow system 1. ID 2000 manages each processing screen in each workflow system 1 by ID. In the processing screen 2001, the name of each processing screen in the workflow system 1 is managed. The client application 2002 manages the URL when accessed from the user terminal 140 for each processing screen 2001. In the Web application 2003, a URL for switching to display on the Web application screen when accessed from a mobile terminal is managed for each processing screen 2001.

  Note that, according to FIG. 22, according to the present invention, “the server determines the Web application URL to be displayed when the determination unit determines that the server has received access from the mobile terminal, and the URL of the client application. An example of “filter setting information storage means for storing a correspondence table in which is associated with” is configured.

  Thus, the server can use the filter setting information in which the URL of the Web application and the URL of the client application are associated with each other.

  In some cases, only the client application 2002 describes a URL, but this is a case where the workflow processing is assumed to be only access from a PC and access from a mobile is not assumed. .

  In this case, if there is an access from a mobile terminal, first, the mobile terminal cannot call the client application 150 in the mobile terminal.

  Further, even if there is a URL corresponding to the URL transmitted from the mobile in the client application 2002, the Web application 160 cannot be called because there is no URL information of the corresponding Web application 2003 (filter setting). (In the case of ID 2000 = 1 and ID 2000 = 3 in the information 2010 and No in S2206 of FIG. 24).

  Note that if the client application 2002 does not have the URL transmitted when accessed from a terminal such as a PC or the user terminal 140 that is a mobile terminal, the corresponding processing screen 2001 cannot be called from the PC. It will be.

  The filter program generation unit 109 generates a filter program to be embedded in the filter processing unit 125 of the workflow server 120.

  FIG. 23 is a flowchart illustrating an example of filter program generation processing of the filter program generation unit 109.

  This filter program is a URL passed as request information from request information (including access destination URL information and access source terminal information) passed to the workflow server 120 when the user terminal 140 accesses the workflow server 120. A process of switching whether to display with a program based on the information or whether to display with a program based on another URL is performed. The processing of this filter program will be described with reference to FIG.

  In S2101 of FIG. 23, the CPU 201 (filter program generation unit 109) of the Web application generation apparatus 100 reads the filter setting information 2010 shown in FIG. 22 into the memory.

  In step S2102, the CPU 201 (filter program generation unit 109) of the Web application generation apparatus 100 reads a source code template for the filter program into the memory. The source code template refers to a source code template that is necessary for the Web application generating apparatus 100 to generate a source code for operating an application. The source code template is stored in the external memory 211 of the Web application generation apparatus 100. Therefore, here, the source code template is read as a step for creating the source of the filter program.

  In step S2103, the CPU 201 (filter program generation unit 109) of the Web application generation apparatus 100 performs source code generation processing from the filter setting information 2010 read in step S2101 and the source code template for the filter program read in step S2102.

  In step S2104, the CPU 201 (filter program generation unit 109) of the Web application generation apparatus 100 compiles the generated source code to generate a filter program. Also, the CPU 201 (filter program generation unit 109) of the Web application generation apparatus 100 archives the compiled source code (filter program) as a library.

  In step S <b> 2105, the CPU 201 (filter program generation unit 109) of the Web application generation apparatus 100 converts the URL for accessing the workflow server 120 into the web.xml file illustrated in FIG. 25 described so as to pass through the compiled filter program. Generate. That is, the web.xml created in S2105 is a setting file for first calling the filter program when the workflow server 120 is accessed from the user terminal 140.

In step S <b> 2106, the CPU 201 (filter program generation unit 109) of the Web application generation apparatus 100 deploys a library (filter program) and web.xml to the filter processing unit 125 of the workflow server 120.
This completes the description of FIG.

  The filter program generation unit 109 constitutes an example of “a filter program generation unit that generates a filter program including the determination unit and the switching unit” according to the present invention.

  As a result, the server can switch between displaying the client application and displaying the Web application depending on whether the access to the server is a terminal or a mobile terminal. A filter program for switching can be generated.

<< Application switching process >>
When the user terminal 140 tries to use the workflow system 1 by accessing the workflow server 120, the filter processing unit 125 switches the application displayed on the terminal on the user terminal 140 side according to the terminal information or the like. Process.

  Next, a process of switching applications displayed on the terminal on the user terminal 140 side by the filter processing unit 125 will be described with reference to FIG.

  In step S <b> 2201, the CPU 201 (filter processing unit 125) of the workflow server 120 receives access from the user terminal 140.

  In S2202, the CPU 201 (filter processing unit 125) of the workflow server 120 refers to the web.xml shown in FIG. 25 deployed at a predetermined position of the workflow server 120 and confirms the URL pattern 2301 for calling the filter program. To do.

  If the URL information included in the request information transmitted when accessing the workflow server 120 from the user terminal 140 (the transmitted URL information is the URL of the client application) matches the URL pattern 2301, the filter program is executed. The CPU 201 (filter processing unit 125) of the workflow server 120 proceeds to the process to the next S2203.

  In addition, when the URL pattern 2301 is described as “/ *”, it means that filtering is performed for any URL pattern of the transmitted URL. For example, the URL pattern 2301 is “/ approve01”. When a fixed value is described in, only URLs having a description of “/ approve01” are filtered.

  In step S2203, the CPU 201 (filter program (filter processing unit 125)) of the workflow server 120 reads terminal information included in the request information. The terminal information includes identifiable information such as whether the terminal is a PC or a mobile.

  In S2204, when it is determined that the terminal information read in S2203 is a PC, in S2205, the CPU 201 (filter program (filter processing unit 125)) of the workflow server 120 displays the client application 150 on the user terminal 140. .

  Accordingly, the server can cause the terminal to display the processing screen of the client application requested by the terminal.

  In S2204, when the terminal information read in S2203 is determined to be a mobile terminal, the CPU 201 (filter program (filter processing unit 125)) of the workflow server 120 proceeds to S2206.

  In S2206, the CPU 201 (filter program (filter processing unit 125)) of the workflow server 120 can display the Web application 160 corresponding to the URL of the request information received in S2201 in the filter setting information 2010 in FIG. It is determined whether or not exists.

  If it is determined in S2206 that a URL exists, in S2207, the CPU 201 (filter program (filter processing unit 125)) of the workflow server 120 sends a Web application corresponding to the URL to the user terminal 140 via a browser. Returns the screen.

  Accordingly, when there is a Web application processing screen corresponding to the client application processing screen requested by the mobile terminal, the server can display the Web application processing screen on the mobile terminal.

  If it is determined in S2206 that the URL does not exist, the screen of the Web application 160 cannot be displayed on the user terminal 140 via the browser, so the CPU 201 of the workflow server 120 (filter program (filter processing unit 125)). Ends this processing.

  Here, the processing after S2203 will be described using an example. For example, when the user terminal 140 accesses the workflow server 120 at “http: // wfserve01 / approve01 /”, the client application 2002 is set to “/ approve01 /” in the settings of 2001 in FIG. (A value of the client application 2002 with ID 2000 = 2 in FIG. 22). According to this setting, as for the reader approval processing screen 2001, the access from the PC is directly processed as a request for the address http: // wfserve01 / approve01 / by the client application 150 (S2205). That is, the application screen of the client application 150 corresponding to the URL of http: // wfserve01 / approve01 / is displayed on the user terminal 140.

  On the other hand, in the case of access from a mobile device, it is confirmed whether there is a setting of the Web application 2003. If it is determined that there is a setting (Yes in S2206), the screen of the Web application 160 is displayed (S2207). .

  For example, when the user terminal 140 accesses the workflow server 120 at “http: // wfserve01 / approve01 /”, the client application 2002 is “/ approve01 /” among the settings of the filter setting information 2010 in FIG. Pay attention to the set part (value of client application 2002 with ID 2000 = 2 in FIG. 22). Next, since it is a case where it is accessed from a mobile, the value of the Web application 2003 corresponding to the client application 2002 is acquired.

  In the Web application 2003 corresponding to the client application 2002 = / approve01 / in FIG. 22, the value “http: // webserve01 / approve /” is set. : // webserve01 / approve / "screen is displayed. In this case, the screen processed by the Web application 160 is displayed on the user terminal 140 (S2207).

  In S2206, in the case of access from a mobile, it is confirmed whether or not there is a URL setting of the Web application 2003. If it is determined that there is no setting (No in S2206), the user terminal 140 , It is impossible to display the screen of the Web application 160, and this process is terminated. At this time, since it cannot be displayed, an error may be displayed.

  The filter processing unit 125 and S2201 to S2204 in FIG. 24 constitute an example of “determination means for determining an access source when access to the client application of the server is accepted” according to the present invention. ing. In addition, according to the present invention, “if the determination unit determines that the server has received access from the terminal, the client application is displayed on the terminal” by the filter processing unit 125 and S2205 in FIG. An example is configured. In addition, according to the filter processing unit 125 and S2207 of FIG. 24, “if the determination unit determines that the server has received an access from a mobile terminal, the Web application screen is displayed to the mobile terminal. An example of “display” is configured.

  Further, when “ID = 2” in FIG. 22 and S2206 in FIG. 24 are Yes, according to the present invention, “the switching unit transmits the request source mobile terminal to the server as request information. An example of “when the URL for displaying the Web application corresponding to the URL of the client application exists in the filter setting information storage unit” is configured. Further, S2207 in FIG. 24 constitutes an example of “displaying the Web application corresponding to the URL for displaying the Web application on the access source mobile terminal” according to the present invention.

  As described above, according to the first embodiment, the Web service interface is set by setting processing information, which is a function that the server performs, without newly developing a process called from an existing client application, to the operation button to be activated. It is possible to provide a Web application generation system that generates a Web application that can be processed via the Web interface.

<Second Embodiment>
Next, the second embodiment will be described.

  In the second embodiment, processes such as an approval process and a drafting process that enable the workflow system 1 to deliver data drafted on the workflow server 120 that exists in the workflow processing unit 123 are Web services. In addition, the filter program already exists, and the Web application generation apparatus 100 receives only the data structure information 121 as design information from the workflow server 120 (for other methods, see the first embodiment). A method for generating a Web application will be described. In the second embodiment, the system accessed by the user terminal 140 is a system that performs workflow processing (workflow system 1).

  First, when the WS interface 124 for invoking the processing of the workflow processing unit 123 exists, the processing of FIG. 4 that is the processing of the server processing program conversion unit 101 does not have to be performed. Therefore, the server processing program conversion unit 101 is not necessary. In the processing of the program generation unit 110 in FIG. 21, the Web service reading and stub code generation processing of S1901 and S1902 is already performed in the program generation unit 110, so this processing is also not performed. Get better.

  That is, the web service publication performed by the processing of FIG. 4 has already been performed by the workflow server 120. At this time, since WSDL is also prepared in advance, regarding which service and which operation of the button such as drafting and approval that can be arranged in the action definition 1701 in FIG. If it is already described in advance in accordance with the WSDL of the workflow server 120, it is not necessary to describe the Web service name and operation name described in WSDL in the processing in FIG. 4 or 1702 in FIG. It will be. Further, as described above, in the workflow server 120, since the Web service of the workflow processing unit 123 is also disclosed and the stub code has already been created in the program generation unit 110, the processing from S1901 to S1902 in FIG. 21 is performed. That means you do n’t have to.

  The workflow processing unit 123 configures an example of “processing information performed by the server in response to a request from the client application” according to the present invention.

  In addition, the WS interface 124 and the “WS interface 124 for invoking the processing of the workflow processing unit 123 exists” and “Web service publication of the second embodiment have already been performed by the workflow server 120.

For this reason, in the second embodiment, the filter program generation unit 109 does not function as a function.

  Furthermore, in the second embodiment, the Web application generation apparatus 100 receives only the data structure information 121 from the workflow server 120, and thereby receives design information of a part other than the process definition necessary for generating the Web application 160. It will be generated.

  It should be noted that S801 in FIG. 10 and “Web application generation device 100 receives only data structure information 121 from workflow server 120” in the second embodiment, “in the design information storage unit” according to the present invention. An example of “data structure information receiving means for receiving the stored data structure information from the server” is configured.

  At least, by receiving item definition information from the data structure information 121 of the workflow server 120 and generating the data model definition 104, the Web application generation device 100 allows the input / output definition 107 (other than the workflow processing definition). It is possible to generate a definition of

  In addition, according to the description of “receiving item definition information from the data structure information 121 of the workflow server 120” and “data structure information 121” in the second embodiment, “used in the client application”. An example of “data structure information that is data item information” is configured.

An example of “a data model definition storing unit that stores the data structure information received from the data structure information receiving unit as a data model definition that is data item information used in the Web application” is configured.

  This eliminates the need for the layout information acquisition unit 105 and the input / output definition conversion unit 106. The input / output definition 107 can be created from the definition information of the data model definition 104 by using the function of the layout editor unit 108.

  Note that in the generation of the Web application 160, the processes related to the design information of the data model definition 104 and the input / output definition 107 are the processes of S1903 to S1907 in FIG. 21 performed by the program generation unit 110 of the first embodiment. The same shall apply.

  As described above, according to the second embodiment, by using the item information of the client application, the existing Web service, and the existing filter program, the Web application can be developed without newly developing a process called from the existing client application. A generation system can be provided. In addition, although it demonstrated centering on a different point from 1st Embodiment, it is the same as that of 1st Embodiment about another part.

  It should be noted that the description of the second embodiment, particularly “the item information of the client application, the existing Web service, and the existing filter program are used, so that a process called from the existing client application is not newly developed. The data model definition according to the present invention and definition information for enabling processing of the existing processing information that can be used by the Web service provided by the Web service providing unit are used. Thus, an example of “generating means for generating a Web application” is configured.
