Abstract

In accordance with one embodiment disclosed herein, a method for Remote Procedure Call (RPC) type Simple Object Access Protocol (SOAP) service access for dynamic web content is provided. The method comprises providing a SOAP RPC Tag Library (TagLib) Tag in a web server page and executing the web server page. The method further comprises creating a SOAP RPC document and sending the SOAP RPC document to an application server. The method further comprises processing the SOAP RPC document, and returning the result of such processing to the Tag.

Claims

1. A method for Remote Procedure Call (RPC) type Simple Object Access Protocol (SOAP) service access for dynamic web content, said method comprising:

providing a SOAP RPC Tag Library (TagLib) Tag in a web server page;

executing said web server page;

creating a SOAP RPC document;

sending said SOAP RPC document to an application server;

processing said SOAP RPC document; and

returning the result of said processing to said Tag.

2. The method of claim 1 wherein said executing is performed in response to a user request.

3. The method of claim 1 wherein said application server is a Java™

version 2 Enterprise Edition (J2EE) application server.

4. The method of claim 1 further comprising, prior to said loading, registering said application server in a registry.

5. The method of claim 4 wherein said registry is a Universal Description, Discovery, and Integration (UDDI) registry.

6. The method of claim 4 further comprising, prior to said loading, if said application server has not been accessed before said loading, requesting information relating to said application server that is registered in said registry and returning said information to said Tag, allowing said Tag to understand the details of said application server.

7. The method of claim 6 wherein said information is Web Services Descriptor Language (WSDL) information.

8. The method of claim 6 wherein said details include details selected from the group consisting of URL, method and/or procedure name, parameters to send, and type of result to expect.

9. The method of claim 1 wherein said TagLib uses Web Services Descriptor Language (WSDL) to correctly create said SOAP document and to correctly interpret said result.

10. The method of claim 1 wherein no proxy is created.

11. The method of claim 1 wherein no custom code is required.

12. The method of claim 1 wherein said web server page is a JavaServer Page (JSP™

).

13. The method of claim 1 wherein said SOAP RPC document is created using eXtensible Markup Language (XML).

14. The method of claim 1 further comprising loading said Tag into said application server.

15. The method of claim 1 further comprising making said result available to said web server page.

16. A system for Remote Procedure Call (RPC) type Simple Object Access Protocol (SOAP) service access for dynamic web content, said system comprising:

a web server page;

a Remote Procedure Call (RPC) type Simple Object Access Protocol (SOAP) Tag contained in said web server page;

a Tag Library (TagLib) in said web server page, said TagLib containing said RPC SOAP Tag; and

an application server operable to communicate with said RPC SOAP Tag.

17. The system of claim 16 wherein said application server is a Java™

version 2 Enterprise Edition (J2EE) application server.

18. The system of claim 16 further comprising a registry.

19. The system of claim 18 wherein said registry is a Universal Description, Discovery, and Integration (UDDI) registry.

20. The system of claim 16 wherein said application server is collocated with said web server page.

21. The system of claim 18 wherein said application server is collocated with said registry.

22. The system of claim 18 wherein said registry is collocated with said web server page.

23. The system of claim 22 wherein said application server is collocated with said registry.

24. The system of claim 18 wherein said application server, said web server page, and said registry are each located remotely from one another.

25. The system of claim 16 wherein said web server page is a JavaServer Page (JSP™

).

26. A system for Remote Procedure Call (RPC) type Simple Object Access Protocol (SOAP) service access for dynamic web content, said system comprising:

means for providing a SOAP RPC Tag Library (TagLib) Tag in a web server page;

means for executing said web server page;

means for creating a SOAP RPC document;

means for sending said SOAP RPC document to an application server;

means for processing said SOAP RPC document; and

means for returning the result of said processing to said Tag.

27. The system of claim 26 further comprising means for registering said application server in a registry.

28. The system of claim 27 further comprising:

means for requesting information relating to said application server that is registered in said registry; and

means for returning said information to said Tag, allowing said Tag to understand the details of said application server.

29. The system of claim 26 wherein said web server page is a JavaServer Page (JSP™

).

30. The system of claim 26 further comprising means for creating said SOAP RPC document using eXtensible Markup Language (XML).

31. Computer-executable software code stored to a computer-readable medium, said computer-executable software code comprising:

code for providing a SOAP RPC Tag Library (TagLib) Tag in a web server page;

code for executing said web server page;

code for creating a SOAP RPC document;

code for sending said SOAP RPC document to an application server;

code for processing said SOAP RPC document; and

code for returning the result of said processing to said Tag.

32. The computer-executable software code of claim 31 further comprising code for registering said application server in a registry.

33. The computer-executable software code of claim 32 further comprising:

code for requesting information relating to said application server that is registered in said registry; and

code for returning said information to said Tag, allowing said Tag to understand the details of said application server.

34. The computer-executable software code of claim 31 wherein said web server page is a JavaServer Page (JSP™

).

35. The computer-executable software code of claim 31 further comprising code for creating said SOAP RPC document using extensible Markup Language (XML).
