Abstract

A method and system for generating schema to Java mapping description. In one embodiment, default schema to Java mapping information is customized into customized schema to Java mapping information. An object having the customized mapping information is created, and schema to Java generation is initialized via the object.

Claims

1. A method comprising:

customizing default schema to Java mapping information into customized schema to Java mapping information;

placing the customized mapping information at a first object; and

initiating schema to Java generation via the first object.

2. The method of claim 1, further comprising placing the default mapping information at a second object, the second object including the first object.

3. The method of claim 2, wherein the second object comprises a schema to Java configuration object, and the first object comprise a schema to Java type info set object.

4. The method of claim 1, further comprising obtaining the customized mapping information from a file, the file comprises an external file including an extensible markup language (XML)-based file.

5. The method of claim 4, wherein the file comprises configuration data having the customized mapping information.

6. The method of claim 5, wherein the configuration data further comprises serializer information.

7. The method of claim 2, wherein the second object comprises a third object to provide access to the customized mapping information and the default mapping information, the third object including a schema to Java type info object.

8. The method of claim 1, wherein the initiating of schema to Java generation includes placing a command to request results from the initiation of the schema to Java generation.

9. The method of claim 8, further comprising generating the requested results, the results including one or more of configuration data, serializers, interfaces, classes, and files.

10. The method of claim 1, wherein the schema to Java generation is performed by a generator residing at a Java 2 Enterprise Edition (J2EE) engine, the generator including a schema to Java generator.

11. The method of claim 1, further comprising generating direct mapping of XML schema and Java interfaces.

12. A system, comprising:

a J2EE engine having a generator, the generator to

load a second object including a first object, the first object having customized schema to Java mapping information; and

generate configuration data having the customized schema to Java mapping information.

13. The system of claim 12, wherein the second object comprises a configuration object having default schema to Java mapping information.

14. The system of claim 12, wherein the first object comprise a schema type info set object having the customized schema to Java mapping information.

15. The system of claim 12, wherein the configuration data further comprises serializer information.

16. The system of claim 12, wherein the generator to generate results, the results comprising one or more of the configuration data, serializers, interfaces, classes, and files.

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

customize default schema to Java mapping information into customized schema to Java mapping information;

place the customized mapping information at a first object; and

initiate schema to Java generation via the first object.

18. The machine-readable medium of claim 17, wherein the instructions which, when executed by the machine, further cause the machine to place creating the default mapping information at a second object, the second object including the first object.

19. The machine-readable medium of claim 18, wherein the second object comprises a schema to Java configuration object, and the first object comprise a schema to Java type info set object.

20. The machine-readable medium of claim 17, wherein the instructions which, when executed by the machine, further cause the machine to generate direct mapping of XML schema and Java interfaces.
