Abstract

A system and method are provided to generate a dynamic web services invocation model. In one embodiment, a first metadata and a second metadata are extracted from description content of a Web Service Definition Language (WSDL) file. The first metadata and the second metadata are inspected. A web service is invoked via a dynamic web services invocation model.

Claims

1. A method comprising:

extracting a first metadata and a second metadata from description content of a Web Service Definition Language (WSDL) file;

inspecting the first metadata and the second metadata; and

invoking a web service via a dynamic web services invocation model.

2. The method of claim 1, further comprising:

identifying the description content of the WSDL file; and

parsing the description content into a first description content and a second description content.

3. The method of claim 1, further comprising

creating a dynamic web services interface model via the first metadata and the second metadata;

and

creating the dynamic web services invocation model in communication with the dynamic web services interface model.

4. The method of claim 3, further comprising providing a dynamic web services invocation application programming interface (API) via the dynamic web services invocation model.

5. The method of claim 3, further comprising providing a dynamic web services interface API via the dynamic web services interface model.

6. The method of claim 1, wherein extracting comprises extracting the first metadata from the first description content, and extracting the second metadata from the second description content.

7. The method of claim 6, wherein the first description content comprises interface description, and the second description content comprises schema type description.

8. The method of claim 1, wherein the first metadata comprises interface metadata, and the second metadata comprises type metadata.

9. The method of claim 8, further comprising creating an interface metadata model via the interface metadata, and creating a type metadata model via the type metadata.

10. A system comprising:

an extractor to extract a first metadata and a second metadata from description content of a Web Service Definition Language (WSDL) file;

an inspection module to inspect the first metadata and the second metadata; and

an invocation module to invoke a web service via a dynamic web services invocation model.

11. The system of claim 10, further comprising:

an identification module to identify the description content of the WSDL file; and

a parser to parse the description content into a first description content and a second description content.

12. The system of claim 10, further comprising:

a first model builder to create a dynamic web services interface model via the first metadata and the second metadata; and

a second model builder to create the dynamic web services invocation model in communication with the dynamic web services interface model.

13. The system of claim 12, wherein the dynamic web services invocation model to provide a dynamic web services invocation application programming interface (API).

14. The system of claim 12, wherein the dynamic web service interface model to provide a dynamic web services interface API.

15. An apparatus comprising:

means for extracting a first metadata and a second metadata from description content of a Web Service Definition Language (WSDL) file;

means for inspecting the first metadata and the second metadata; and

means for invoking a web service via a dynamic web services invocation model.

16. The apparatus of claim 15, further comprising:

means for identifying the description content of the WSDL file; and

means for parsing the description content into a first description content and a second description content.

17. The apparatus of claim 15, further comprising means for creating a dynamic web services interface model via the first metadata and the second metadata;

and

means for creating the dynamic web services invocation model in communication with the dynamic web services interface model.

18. An article of manufacture comprising a machine-accessible medium having instructions which when executed cause a machine to:

extract a first metadata and a second metadata from description content of a Web Service Definition Language (WSDL) file;

inspect the first metadata and the second metadata; and

invoke a web service via a dynamic web services invocation model.

19. The article of manufacture of claim 18, wherein the instructions which when executed further cause the machine to:

identify the description content of the WSDL file; and

parse the description content into a first description content and a second description content.

20. The article of manufacture of claim 18, wherein the instructions which when executed further cause the machine to:

create a dynamic web services interface model via the first metadata and the second metadata; and

create the dynamic web services invocation model in communication with the dynamic web services interface model.
