there are no stubs with ws4ee in jboss. You can do a client side deployment with <service-ref> elements in application-client.xml and look up a preconfigured javax.xml.rpc.Service from JNDI.
An alternative is dynamic invocation (DII) through a javax.xml.rpc.Service that your configure yourself.
We use both styles in our webservice/samples and from webservice/testsuite.
I'll also put the DII style on the wiki.
Don't use Axis wsdl2java or similar tools. The stubs they produce will probably not be portable.
