Description

  The present invention relates to a computer and a program that execute a program that runs on a client but does not run on a browser, and that receives a response from the client by sending a processing request to a program that runs on the server without running on the WWW server. It is about.

  Conventionally, a WWW browser analyzes the contents of an html-format document, and automatically downloads from the server when resources necessary for operating a Java program (applet) do not exist in the client. With this mechanism, the Java program can be operated even if the resource required for the Java program is a resource that does not exist in the client.

  However, resources other than programs created in C language or COBOL language or Java programs are not subject to download. For this reason, in order for the Java program to operate normally, existing resources that are not managed by the WWW browser need to be arranged on the client side in advance.

  If the existing resource is a program that operates in the server environment, the WWW browser downloads all the resources necessary for operation to the client environment, so that the existing resource in the server environment is executed from the Java program in the client environment. To do this, the program developer had to develop the program.

(1) As described above, in order for a Java program using a conventional WWW browser to operate normally, existing resources must be arranged in the client environment in advance. In such a system, every time the contents of existing resources are updated, there is a problem that it is necessary to replace the existing resources arranged in the client environment, and all necessary resources are arranged and operated on the server. This causes a problem that the advantage of the Java program is lost.

  (2) When the existing resource is a program that operates in a server environment, there is a problem that a program that operates in the server environment cannot be operated from a Java program downloaded to the client side.

  In order to solve these problems, the present invention automatically downloads an OS-dependent program from a server without operating on a browser to a client and operates it, or does not operate on a server-side WWW server. The purpose is to run the program automatically and receive the results.

  Means for solving the problem will be described with reference to FIG.

  In FIG. 1, a client 1 is a terminal that performs various business operations, and here stores a WWW browser 2, a property file 4, a program A, a program B, and the like.

  The WWW browser 2 performs various processes based on an html document and the like. Here, the programs A and B (for example, Java programs A and B) are operated to perform various processes without depending on the OS (operating system). It is for executing business processing (platform).

  The program A is a program that runs on the browser and performs various processes according to the property file 4.

  The property file 4 is registered with information necessary for the program to execute.

  The program B is a program that is downloaded from the server 11 and operates on the browser.

  The server 11 provides various services to the client 1, and here stores a WWW server 12, a program B, an existing client resource B, and the like.

The WWW server 12 provides various services to the browser based on an html document or the like.

  Next, the operation will be described.

  The program A operating on the browser 2 of the client 1 downloads and starts the program B from the server side based on the property file 4, and the started program B starts its operation and performs the processing instructed by the program A. The result is returned to the program A, and the result of the response received by the program A is output.

  At this time, the program A operating on the browser 2 is a program independent of the operating system, and the program B operating on the client 1 but not operating on the browser 2 is an operating system dependent program.

  In addition, the program A is a Java program, and the program B is an operating system dependent program that runs on the client.

  In addition, data is downloaded at the same time or when necessary, and the program B uses the downloaded data to execute processing.

  Further, the program A operating on the browser 2 of the client 1 calls the program B operating on the WWW server 12 of the server 11 based on the property file 4 and requests the processing, and the server A that is called and receives the processing request. Program B running on the WWW server 12 requests processing to the program C running on the server instead of running on the WWW server, receives the result, returns it to the program A, and runs on the browser of the client that received the reply The result received by the program A is output (see the flowchart in FIG. 6).

  At this time, the programs A and B operating on the browser or the WWW server are programs independent of the operating system, and the program C operating on the server without operating on the browser is an operating system dependent program.

  In addition, the programs A and B are Java programs, and the program C is an operating system dependent program that runs on the server.

  Therefore, the OS-dependent program is automatically downloaded from the server to the client without operating on the browser, and the OS-dependent program is automatically executed without operating on the server-side WWW server. It becomes possible to receive.

The present invention automatically downloads an OS-dependent program from a server without operating on a browser to a client and operates it, or automatically executes an OS-dependent program without operating on a WWW server on the server side. Because it adopts a configuration to receive the results, it was a problem with the conventional technology.
(1) In order for the Java program to operate normally on a conventional browser, existing resources had to be arranged in the client environment in advance. However, according to the present invention, the existing resources can be arranged on the server side. It is no longer necessary to replace existing resources placed in the client environment every time the contents of existing resources are deceived, and a convenient operation is possible in which all necessary resources can be placed on the server and managed collectively. .

  (2) If the existing resource is a program that operates in the server environment, the program that operates in the server environment can be operated from the Java program downloaded to the client side, and only the result can be received on the client side. Became.

  The present invention automatically downloads an OS-dependent program from a server without operating on a browser to a client and operates it, or automatically executes an OS-dependent program without operating on a WWW server on the server side. You can realize to receive the result.

When a file (a program that does not operate on the WWW browser but operates on the client, for example, a COBOL program and its data file) is downloaded, the client's Java program downloads the COBOL program to execute the process. The result can be received and displayed on the screen.

  As a result, the download of the COBOL program that does not operate on the WWW browser of the client 1 can be received when the process execution becomes necessary, the process can be executed, and the result can be received and displayed on the screen. In addition, there is no need for the COBOL program on each client side to perform bug correction of the COBOL program that occurs when the result is received by calling and executing the processing while the COBOL program is placed on the client, and the server side does not have to The COBOL program can be held and corrections can be performed at once.

  FIG. 6 shows a flowchart for explaining the operation of the present invention (execution of server program B).

  In FIG. 6, a property file is read in S31. This is because a program (a Java program for server program execution created automatically in FIG. 4) operating on the WWW browser 2 of the client 1 reads a property file (a property file 4 for server program execution created in FIG. 2).

  In step S32, the Java program is executed.

  In S33, it is determined whether to execute the server program. This refers to the property file 4 read in S21 and determines whether to execute the server program. In the case of YES, the processing after S33 is executed. In the case of NO, it has been found that the file is not a property file for executing the server program.

  In S34, the Java program on the client calls the Java program and passes parameters in order to execute the server program. Here, a Java program operating on the WWW server of the server 11 is called and passed with the following data shown in the figure as parameters.

-Parameter-Server program name In S35, the Java program on the server executes the server program (COBOL program).

  In S36, the COBOL program performs business processing.

  In S37, the COBOL program notifies the Java program of the result, and the process ends.

  In S38, the client Java program receives the result and resumes the processing.

As described above, the Java of this embodiment that operates on the WWW browser of the client 1.
The program reads the property file 4 of the present embodiment, calls the server Java program, passes parameters (server program name, for example, COBOL program name), causes the COBOL program running on the server to execute the business process, and returns the result. It can be received, notified to the Java program of the client, passed and displayed on the screen or the like.

  As a result, a COBOL program that does not run on the WWW server of the server 11 can be executed on the server 11 and the result can be received and displayed by the Java program on the client WWW browser. There is no need to hold a COBOL program that does not run on a WWW browser, run it, and read the result, run the COBOL program on the server 11 to receive only the result, and perform maintenance management of the COBOL program at once. Can be performed by the server on the center side.
