Abstract

A method and system for directly mapping web services interfaces and Java interfaces. In one embodiment, a web services mapping is generated from a common mapping descriptor associated with a web services interface; updated mapping information is received, and, based on the web services mapping and the updated mapping information, a customized interface comprising a common web services and web services client interface is generated.

Claims

1. A method, comprising:

generating, using at least one processor, a web services mapping from a common mapping descriptor associated with a web services interface;

receiving an update to mapping information including an update to web services interface mapping information stored in a first mapping model and an update to schema-to-Java mapping information stored in a second mapping model; and

generating, based on the web services mapping and the update to the mapping information, a customized interface comprising a common interface for web services to be employed in a server and for a web services client to be employed in a client, the common interface to provide direct mapping between the first mapping model, the second mapping model, and the common mapping descriptor, wherein the customized interface is a service endpoint interface to specify methods of a Java class that are to be exposed as web services operations.

2. The method of claim 1, wherein the common mapping descriptor used to generate the web services mapping comprises a Web Services Description Language (WSDL) file.

3. The method of claim 1, wherein the first mapping model comprises a Web Services Description Language (WSDL) interface mapping model and the second mapping model comprises a Schema-to-Java mappings model.

11. The method of claim 1, the service endpoint interface including a web services client proxy and a web services implementation endpoint.

12. The method of claim 1, wherein the updated mapping information comprises common mapping information for the web services and the web services client.

13. The method of claim 1, wherein the updated mapping information is received from an administrative tool.

14. The method of claim 1, further comprising generating a direct mapping between a web services interface and a web services client interface.

15. The method of claim 1, further comprising storing the updated mapping information in the common mapping descriptor.

4. A system, comprising:

at least one processor, an initialization module to initialize, using the at least one processor, a web services mapping from a common mapping descriptor associated with a web services interface; and

a proxy generator to

receive an update to mapping information including an update to web services interface mapping information stored in a first mapping model and an update to schema-to-Java mapping information stored in a second mapping model, and

generate, based on the web services mapping and the update to the mapping information, a customized interface comprising a common interface for web services to be employed in a server and for a web services client to be employed in a client, the common interface to provide direct mapping between the first mapping model, the second mapping model, and the common mapping descriptor, wherein the customized interface is a service endpoint interface to specify methods of a Java class that are to be exposed as web services operations.

5. The system of claim 4, wherein the common mapping descriptor comprises a Web Services Description Language (WSDL) file.

6. The system of claim 4, wherein the first mapping model comprises a Web Services Description Language (WSDL) interface mapping model and the second mapping model comprises a Schema-to-Java mappings model.

16. The system of claim 4, the service endpoint interface including a web services client proxy and a web services implementation endpoint.

17. The system of claim 4, wherein the updated mapping information comprises common mapping information for the web services and the web services client.

18. The system of claim 4, further comprising an administrative tool to provide the updated mapping information.

19. The system of claim 4, wherein the proxy generator is to generate a direct mapping between a web services interface and a web services client interface.

20. The system of claim 4, wherein the proxy generator is to store the updated mapping information in the common mapping descriptor.

7. A non-transitory machine-readable storage medium having stored thereon data representing sets of instructions which, when executed by a processor of a machine, cause the machine to perform operations comprising:

generating a web services mapping from a common mapping descriptor associated with a web services interface;

receiving an update to mapping information including an update to web services interface mapping information stored in a first mapping model and an update to schema-to-Java mapping information stored in a second mapping model; and

generating, based on the web services mapping and the update to the mapping information, a customized interface comprising a common interface for web services to be employed in a server and for a web services client to be employed in a client, the common interface to provide direct mapping between the first mapping model, the second mapping model, and the common mapping descriptor, wherein the customized interface is a service endpoint interface to specify methods of a Java class that are to be exposed as web services operations.

8. The non-transitory machine-readable storage medium of claim 7, wherein the updated mapping information comprises common mapping information for the web services and the web services client.

9. The non-transitory machine-readable storage medium of claim 7, wherein the operations further comprise receiving the updated mapping information from an administrative tool.

10. The non-transitory machine-readable storage medium of claim 7, wherein the operations further comprise generating a direct mapping between a web services interface and a web services client interface.
