Abstract

A method and system for directly mapping web services interfaces and Java interfaces. In one embodiment, default mapping information is identified, the default mapping information having default interface mapping information and default schema to Java mapping information. The default mapping information is then update and a mapping descriptor having the updated mapping information is generated. The updated information contains updated interface mapping information and updated schema to Java mapping information.

Claims

1. A method, comprising:

obtaining default mapping information corresponding to at least one of web services to be deployed in a server and a web services client to be deployed in a client;

transforming, using at least one processor, the default mapping information into updated mapping information for compatibility with a common interface for the web services and the web services client, wherein the updated mapping information comprises updated interface mapping information and updated schema-to-language-specific mapping information;

storing the updated interface mapping information in a first mapping model of the common interface;

storing the updated schema-to-language-specific mapping information in a second mapping model of the common interface; and

including the first mapping model, the second mapping model, and a common mapping descriptor in a deployment of at least one of the web services and the web services client.

2. The method of claim 1, wherein the common interface provides direct mapping between a web services interface and a language-specific interface.

3. The method of claim 2, wherein the language-specific interface comprises a Java interface.

4. The method of claim 1, wherein the updated schema-to-language-specific mapping information comprises updated schema-to-Java mapping information.

5. The method of claim 1, wherein the default mapping information comprises information stored in a Java Application Programming Interface-based Extensible Markup Language Remote Procedure Call (JAX-RPC) file.

6. The method of claim 1, wherein the common mapping descriptor comprises a Web Service Description Language (WSDL) model, and the first mapping model comprises a WSDL interface mapping model.

7. The method of claim 6, wherein the WSDL interface mapping model describes mappings between a service endpoint interface (SEI) and a representation in WSDL of the SEI.

8. The method of claim 1, wherein the second mapping model comprises a schema-to-Java mapping model.

9. The method of claim 1, wherein the transforming of the default mapping information into the updated mapping information is performed via an administrative tool.

10. The method of claim 1, further comprising:

initializing the default mapping information prior to the transforming of the default mapping information into the updated mapping information.

11. The method of claim 1, wherein the common interface comprises an SEI to specify methods of a class that are to be exposed as web services operations.

12. The method of claim 11, wherein the SEI comprises at least one of a web services client proxy and a web services implementation endpoint.

13. A transitory machine-readable storage medium comprising instructions that, when executed by at least one processor of a machine, cause the machine to perform operations comprising:

obtaining default mapping information corresponding to at least one of web services to be deployed in a server and a web services client to be deployed in a client;

transforming the default mapping information into updated mapping information for compatibility with a common interface for the web services and the web services client, wherein the updated mapping information comprises updated interface mapping information and updated schema-to-language-specific mapping information;

storing the updated interface mapping information in a first mapping model of the common interface;

storing the updated schema-to-language-specific mapping information in a second mapping model of the common interface; and

including the first mapping model, the second mapping model, and a common mapping descriptor in a deployment of at least one of the web services and the web services client.

14. A system comprising:

at least one hardware processor; and

memory comprising instructions that, when executed by the at least one hardware processor, cause the system to perform operations comprising;

obtaining default mapping information corresponding to at least one of web services to be deployed in a server and a web services client to be deployed in a client;

transforming the default mapping information into updated mapping information for compatibility with a common interface for the web services and the web services client, wherein the updated mapping information comprises updated interface mapping information and updated schema-to-language-specific mapping information;

storing the updated interface mapping information in a first mapping model of the common interface;

storing the updated schema-to-language-specific mapping information in a second mapping model of the common interface; and

including the first mapping model, the second mapping model, and a common mapping descriptor in a deployment of at least one of the web services and the web services client.

15. The system of claim 14, wherein the common interface provides direct mapping between a web services interface and a language-specific interface.

16. The system of claim 15, wherein the language-specific interface comprises a Java interface.

17. The system of claim 14, wherein the updated schema-to-language-specific mapping information comprises updated schema-to-Java mapping information.

18. The system of claim 14, wherein the default mapping information comprises information stored in a Java Application Programming Interface-based Extensible Markup Language Remote Procedure Call (JAX-RPC) file.

19. The system of claim 14, wherein the common mapping descriptor comprises a Web Service Description Language (WSDL) model, the first mapping model comprises a WSDL interface mapping model describing mappings between a Java service endpoint interface (SEI) and a representation in WSDL of the Java SEI, and the second mapping model comprises a schema-to-Java mapping model.

20. The system of claim 14, wherein the common interface comprises an SEI to specify methods of a class that are to be exposed as web services operations, and wherein the SEI comprises at least one of a web services client proxy and a web services Java implementation endpoint.
