I've uploaded the patch in the JIRA issue.
I have this problem too, but don't consider like a bug.
I work it around with (after read many jbossws code):
service.addPort(portName, SOAPBinding.SOAP11HTTP_BINDING, endpointAddress);
where "endpointAddress" is your "url" and "portName" is the same "portQName".
this must be before dispach creation.
I think it's a bug.
The JAX-WS 2.0 specification states (in sections 4.3.1 and 18.104.22.168) the support for this property is mandatory.
