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 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;

accessing interface mapping information for compatibility of at least one interface of a web service application and at least one interface of a web service client application with a common interface;

accessing schema-to-language-specific mapping information for compatibility of at least one schema of the web service application and at least one schema of the web service client application with a language specific interface; and

deploying at least one of the web service application and the web service client application together with the interface mapping information, the schema-to-language-specific mapping information, and a common mapping descriptor.

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

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

4. The system of claim 3, wherein the schema-to-language-specific mapping information comprises schema-to-Java mapping information.

5. The system of claim 1, wherein the interface mapping information is generated based on respective interface information of the web service application the web service client application, the respective interface information comprising information stored in a Java Application Programming Interface-based Extensible Markup Language Remote Procedure Call (JAX-RPC) file.

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

7. The system 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 system 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.

9. The system of claim 8, wherein the SEI comprises at least one of a web services client proxy and a web services implementation endpoint.

10. A method comprising:

accessing interface mapping information for compatibility of at least one interface of a web service application and at least one interface of a web service client application with a common interface;

accessing schema-to-language-specific mapping information for compatibility of at least one schema of the web service application and at least one schema of the web service client application with a language specific interface; and

deploying at least one of the web service application and the web service client application together with the interface mapping information, the schema-to-language-specific mapping information, and a common mapping descriptor.

11. The method of claim 10, wherein the common interface provides direct mapping between a web services interface and a language-specific interface.

12. The method of claim 11, wherein the language-specific interface comprises a Java interface.

13. The method of claim 12, wherein the schema-to-language-specific mapping information comprises schema-to-Java mapping information.

14. The method of claim 10, wherein the interface mapping information is generated based on respective interface information of the web service application the web service client application, the respective interface information comprising information stored in a Java Application Programming Interface-based Extensible Markup Language Remote Procedure Call (JAX-RPC) file.

15. The method of claim 10, wherein the common mapping descriptor comprises a Web Service Description Language (WSDL) model, and the interface mapping information comprises a WSDL interface mapping model.

16. The method of claim 15, wherein the WSDL interface mapping model describes mappings between a service endpoint interface (SEI) and a representation in WSDL of the SEI.

17. The method of claim 10, wherein the common interface comprises an SEI to specify methods of a class that are to be exposed as web services operations.

18. The method of claim 17, wherein the SEI comprises at least one of a web services client proxy and a web services implementation endpoint.

19. A non-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:

accessing interface mapping information for compatibility of at least one interface of a web service application and at least one interface of a web service client application with a common interface;

accessing schema-to-language-specific mapping information for compatibility, of at least one schema of the web service application and at least one schema of the web service client application with a language specific interface; and

deploying at least one of the web service application and the web service client application together with the interface mapping information, the schema-to-language-specific mapping information, and a common mapping descriptor.

20. The machine-readable storage medium of claim 19, wherein:

the common interface provides direct mapping between a web services interface and a language-specific interface;

the language-specific interface comprises a Java interface; and

the schema-to-language-specific mapping information comprises schema-to-Java mapping information.
