Abstract

A share memory service system and method of web service oriented applications, which includes the steps of declaring an object requiring to be shared of a plurality of web services as a shared object, storing the shared object to a shared virtual memory, and providing the shared object of the shared virtual memory for the access of the web services and a plurality of clients. Accordingly, a shared virtual memory may be simulated in any web service oriented applications, and the method of managing the shared virtual memory providing a way for web services of application program to access the shared object directly instead of invoking each other through the external call. Hence the complexity of service oriented applications development may be reduced.

Claims

1. A share memory service system of web service oriented applications applying to a network constructed of a plurality of clients, comprising:

a plurality of web services, which provides a specific web service for the clients required the specific web service, and each of the web services shares the private object as a shared object with other web services;

a shared virtual memory, which stores the shared object; and

a share memory service, which maintains the shared object and processes a request message of accessing the shared object issuing from the web services.

2. The system of claim 1, wherein the share memory service further comprising:

a session controller, which processes the request message issuing from each of the web services, verifies the legality of each of the web services, and check a unique session ID of the request message;

a memory binder, which initials the shared virtual memory for the shared object newly declared, and provides the shared object for the web services;

an access controller, which comprises at least one access synchronizer for guaranteeing the concurrency control among the shared objects and the performance of the web services are correct; and

a garbage collector, which performs the update and reuse of the shared virtual memory, and releases the space while the life cycle of the shared object terminated.

3. The system of claim 2, wherein the session controller further comprising:

a web service verifier, which verifies the legality of each of the web services for refusing the imitated web service;

a web service registry, which stores an information of the legal web service;

a UID generator, which assigns the unique session ID to each of the web services while the web services invokes the shared memory service in the first time; and

a request processor, which cooperates with the memory binder for obtaining a default space of the shared virtual memory.

4. The system of claim 1, wherein the network is at least one selected from the group consisting of an Internet and an Intranet.

5. The system of claim 1, wherein the clients invoke the web services following a SOAP (simple object access protocol), and the request message issued from the web service having at least one SOAP.

6. The system of claim 1, wherein the web services interacts with each other through a request message comprising at least a SOAP and a session information.

7. The system of claim 1, wherein the object is at least one selected from the group consisting of a global object and a local object, and the shared object is at least one selected from the group consisting of a global shared object and a local shared object.

8. The system of claim 3, wherein the memory binder binds the shared object to the web services according to the unique session ID, and the web services, the shared memory service, the session controller, the memory binder, the access controller, the access synchronizer, the garbage collector, the web service verifier, the web service registry, the UID generator and the request processor is implemented respectively in at least one programming language selected from the group consisting of Java, Visual Basic and C++.

9. The system of claim 7, wherein the shared virtual memory further comprising:

a global shared object database, which stores the global shared object; and

a local shared object database, which stores the local shared object.

10. A share memory service method of web service oriented applications applying to a network constructed of a plurality of clients, comprising:

declaring an object requiring to be shared of a plurality of web services as a shared object;

storing the shared object to a shared virtual memory; and

providing the shared object of the shared virtual memory for the access of the web services and a plurality of clients.

11. The method of claim 10, wherein the network is at least one selected from the group consisting of an Internet and an Intranet.

12. The method of claim 10, wherein the clients invoke the web services following a SOAP (simple object access protocol), and a request message issued from the web service having at least one SOAP.

13. The method of claim 10, wherein the web services interacts with each other through a request message comprising at least a SOAP and a session information.

14. The method of claim 10, wherein the object is at least one selected from the group consisting of a global object and a local object, and the shared object is at least one selected from the group consisting of a global shared object and a local shared object.

15. The method of claim 14, wherein the shared virtual memory further comprising:

a global shared object database, which stores the global shared object; and

a local shared object database, which stores the local shared object.
