Could you possibly be using the (older) Crimson parser instead of Xerces? IIRC Crimson has problems with namespaces--which may account for the error that you are getting. I believe Crimson is the default with JDK 1.4.
In addition, to simplify your problem, you may wish to run the simple POJO example on the quickstart page[1] and see if you can get the WSDL to appear with *that* example. If not, I would forget your code for the moment and instead concentrate on getting the simple POJO case to work.
