Abstract

A simulator machine obtains IDL information from an IDL definition storage, and automatically builds up a function of a server application or a client application based on the IDL information obtained. The simulator machine is connected to a WWW server that is one of nodes. Each of the rest of the nodes can access the WWW server by starting a WWW Browser thereby to build up on its own node a function of a server simulator or a client simulator that is provided by the simulator machine.

Claims

1. A distributed-object development system for developing a client application to be executed by a client that is one of a plurality of nodes for calling an object or a server application to be executed by a server that is one of the plurality of nodes for providing services by the object under a distributed-object environment where the objects are distributed to the plurality of nodes on a network, the distributed-object development system comprising:

a server application simulator that defines information on the type of the object, obtains interface definition information for intermediating between the client application and the server application, simulates a response in reply to a call request for the object issued by the client application by the simulator generating the response based on the obtained information instead of obtaining the response from a procedure that actually implements the object, and transmits the generated response to the client application, where the call request passes from the client application to the server application simulator through an object request broker; and

a client application simulator that obtains the interface definition information, simulates an other call request for the object by the simulator generating the other request based on the obtained information, transmits the generated request to the server application, and receives a response transmitted from the server application in reply to the request.

2. The distributed-object development system according to claim 1, wherein at least one of the plurality of nodes is equipped with the server application simulator or the client application simulator, and a desired node out of the rest of the nodes other than the above node controls the simulation function of at least one of the server application simulator and the client application simulator via the network.

3. The distributed-object development system according to claim 2, wherein a simulation function for the server application simulator and the client application simulator is provided on a WWW (Worldwide Web) server that is one of the nodes, and one other node out of the rest of the nodes controls the simulation function via a WWW Browser.

4. The distributed-object development system according to claim 1, wherein, when the contents of the call request for the object issued by the client application do not coincide with a type according to the definition of the interface, the server application simulator prepares a verification file by adding the information showing non-coincidence of type to the contents of the generated response.

5. The distributed-object development system according to claim 1, wherein, when the contents of the response returned from the server application do not coincide with the type according to the definition of the interface, the client application simulator generates a verification file by adding the information showing non-coincidence of type to the contents of the generated request.

6. A computer-readable recording medium recorded with a program for developing a client application to be executed by a client that is one of a plurality of nodes for calling an object or a server application to be executed by a server that is one of the plurality of nodes for providing services by the object under a distributed-object environment where the objects are distributed to the plurality of nodes on a network, wherein the recording medium is recorded with a program that executes:

selecting the simulation of either the server application or the client application;

obtaining interface definition information that defines information on the type of the object and intermediates between the client application and the server application;

simulating a response according to a call request for the object from the client application by the simulator generating the response based on the obtained interface information instead of obtaining the response from a procedure that actually implements the object, when the simulation of the server application has been selected;

transmitting to the client application the response generated, where the call request passes from the client application to the server application simulator through an object request broker;

simulating an other call request for the object, by the simulator generating the other request based on the obtained interface information, when the simulation of the client application has been selected;

transmitting to the server application a request generated and receiving a response transmitted from the server application according to the request, where the call request passes from the client application to the server application simulator through an object request broker.

7. A distributed-object development system for developing a client application to be executed by a client that is one of a plurality of nodes for calling an object or a server application to be executed by a server that is one of the plurality of nodes for providing services by the object under a distributed-object environment where the objects are distributed to the plurality of nodes on a network, the distributed-object development system comprising:

a server application simulator that defines information on the type of the object, obtains interface definition information for intermediating between the client application and the server application, simulates a response in reply to a call request for the object issued by the client application by the simulator generating the response based on the obtained information instead of obtaining the response from a procedure that actually implements the object, and transmits the generated response to the client application, where the call request passes from the client application to the server application simulator through an object request broker.

8. A distributed-object development system according to claim 7, further comprising:

a client application simulator that obtains the interface definition information, simulates another call request for the object by generating the other request based on the obtained information, transmitting the generated request to the server application through the object request broker, and receives a response transmitted from the server application in reply to the request.

9. A distributed-object development system according to claim 7, wherein the server application simulator is interactively controllable through a graphical user interface which allows interactive configuration of a log relating to the server application simulator'"'"'s simulation of the response, interactive control of execution of the server application simulator, or interactive configuration of test values to be included in the simulated response.

10. A distributed-object development system according to claim 9, wherein the interactive configuration of test values to be included in the simulated response is based on the interface definition information.

11. A distributed-object development system according to claim 9, wherein the graphical user interface provides an interface for interactively accessing the log relating to the server application simulator'"'"'s simulation of the response.
