Abstract

A method and system for creating a common model. In one embodiment, a web services model and a web service client model are identified. The web services and web services client models are then unified to create a common model.

Claims

1. A method comprising:

identifying web services properties associated with a web services model;

identifying web services client properties associated with a web services client model;

extracting common properties from the web services properties and the web services client properties; and

creating, using one or more processors, a single common model by using the common properties and unifying the web services model and the web services client model, the single common model comprising;

a Web Services Description Language (WSDL) model describing a structure of web services;

a WSDL interface mappings model describing mappings between a JAVA service endpoint interface and WSDL representation of the JAVA service endpoint interface;

a schema to JAVA mappings model describing mappings between schema definition types and JAVA classes representing the schema definition types; and

a configuration model describing a configuration of the web services model and the web services client model;

the configuration model referencing the WSDL model and the WSDL interface mappings model, the WSDL interface mapping model referencing the WSDL model and the schema to JAVA mappings model, and the schema to JAVA mappings model referencing the WSDL model;

the common model serving as a basis for development of web services corresponding to the web services model and for development of a web services client corresponding to the web services client model.

2. The method of claim 1, the development of the web services and the development of the web services client each comprising:

updating mapping information, the updated mapping information comprising updated interface mapping information and updated schema to JAVA mapping information;

storing the updated interface mapping information at the WSDL interface mappings model; and

storing the updated schema to JAVA mappings mapping information at the schema to JAVA mappings model.

3. The method of claim 1, wherein the configuration model having comprises configuration information relating to an interface described in a web services interface description included in the WSDL model.

4. A system having a memory and further comprising:

an identification module to;

identify web services properties associated with a web services model,

identify web services client properties associated with a web services client model, and

extract common properties from the web services properties and the web services client properties; and

a generator, using a processor, to create a single common model by using the common properties and unifying the web services model and the web services client model, the single common model comprising;

a Web Services Description Language (WSDL) model describing a structure of web services;

a WSDL interface mappings model describing mappings between a JAVA service endpoint interface and a WSDL representation of the JAVA service endpoint interface;

a schema to JAVA mappings model describing mappings between schema definition types and JAVA classes representing the schema definition types; and

a configuration model describing a configuration of the web services model and the web services client model;

the configuration model referencing the WSDL model and the WSDL interface mappings model, the WSDL interface mapping model referencing the WSDL model and the schema to JAVA mappings model, and the schema to JAVA mappings model referencing the WSDL model;

the common model serving as a basis for development of web services corresponding to the web services model and for development of a web services client corresponding to the web services client model.

5. The system of claim 4, further comprising an updating tool to:

update mapping information, the updated mapping information comprising updated interface mapping information and updated schema to JAVA mapping information,

store the updated interface mapping information at the WSDL interface mappings model; and

store the updated schema to JAVA mappings mapping information at the schema to JAVA mapping mappings model.

6. The system of claim 4, wherein the WSDL model comprises a web services interface description.

7. The system of claim 6, wherein the configuration model comprises configuration information relating to an interface described in the web services interface description.

8. The system of claim 4, wherein the common model includes a JAVA-based common model residing at a JAVA 2 Enterprise Edition (J2EE) engine.

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

identify web services properties associated with a web services model;

identify web services client properties associated with a web services client model;

extract common properties from the web services properties and the web services client properties; and

create a single common model by using the common properties and unifying the web services model and the web services client model, the single common model comprising;

a Web Services Description Language (WSDL) model describing a structure of web services;

a WSDL interface mappings model describing mappings between a JAVA service endpoint interface and a WSDL representation of the JAVA service endpoint interface;

a schema to JAVA mappings model describing mappings between schema definition types and JAVA classes representing the schema definition types; and

a configuration model describing a configuration of the web services model and the web services client model;

the configuration model referencing the WSDL model and the WSDL interface mappings model, the WSDL interface mapping model referencing the WSDL model and the schema to JAVA mappings model, and the schema to JAVA mappings model referencing the WSDL model;

the common model serving as a basis for development of web services corresponding to the web services model and for development of a web services client corresponding to the web services client model.

10. The machine-readable storage medium of claim 9, wherein the sets of instructions which, when executed by the machine, further cause the machine to:

update mapping information, the updated mapping information comprising updated interface mapping information and updated schema to JAVA mapping information;

store the updated interface mapping information at the WSDL interface mappings model; and

store the updated schema to JAVA mappings mapping information at the schema to JAVA mappings model.

11. The machine-readable storage medium of claim 9, wherein the WSDL model comprises a web services interface description.
