A J2EE Webservice client needs 4 components
2) jaxrpc-mapping.xml - to preserve the java & wsdl mapping
3) Java types (SEI + JavaBeans)
4) service-ref tag in whatever your deployment descriptor is
If you are starting development from a wsdl file then you will only have 1, and will need to generate 2 and 3, and hand code 4.
The following wscompile command will do this for you:
wscompile -keep -import -f:wsi -mapping jaxrpc-mapping.xml config.xml
If your webservice is a document/literal webservice, you can control whether wscompile generates a wrapped, or bare service endpoint interface by using -f:unwrap, and -f:dontunwrap respectively
Since wscompile expects a plain JAX-RPC client (and not a J2EE client), it generates a bunch of sun implementaiton classes (like serializers). The only types you need are the plain JavaBeans that represent complex types in your wsdl file.
