Ok beware that JAXWS 2.0.1ea nightly builds can be very unstable. If you
need stability of the bits use JAXWS 2.0 FCS.

Where did you get the java interface?

Yes. Typically, the JAXWS client side programming model with java 5 is
to generate needed classes from the WSDL.
Included in these generated classes would be the service class and the
java sei reflecting the wsdl to java
mapping, along with any javabean classes. The service class would be
instantiated and the getPort() method
invoked on the service.
Generating needed classes is done using the wsimport tools. Please read
the Users guide that comes with jaxws 2.0
regarding tool use.
After you read this info on wsimport let us know if you have any questions-
