How-to Create Top-Down Document Literal Web service

This example shows how to develop a Document Literal style webservice for Oracle 10iAS using the Top-Down paradigm. Document Literal webservices are services that process xml documents. The Top-Down paradigm implies that you are starting with a WSDL and will write the implementation classes after the WSDL has been processed and the necessary service classes and interfaces are generated. Once the generation process is complete your implementation class can be compiled and included into the webservice archive (EAR file) to be deployed to OC4J. For your convenience this example has an implementation class and corresponding source code.
