In this screen specify the WSDL file that will be used for generating the necessary classes.
WSDL is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information. The operations and messages are described abstractly, and then bound to a concrete network protocol and message format to define an endpoint. Related concrete endpoints are combined into abstract endpoints (services).
You can also choose whether to generate JAX-RPC stubs. If you check this option, the non-portable JAX-RPC stubs will be generated. These objects are not needed for J2EE clients, but may be needed for other clients.
