Failed to create web service client for eventing web service

I tried to setup the saples fro ws-eventing of JBossWS, I managed to compile an deploy the sample under JBoss AS, however when I try to run the unit tests they fail on the line trying to instantiate the webservice client:

in file EventingSupport.java
protected void setUp() throws Exception

{ ... Service service = Service.create(wsdlLocation, new QName("http://schemas.xmlsoap.org/ws/2004/08/eventing","EventingService")); .... }

}

with stack trace

The wsdlLocation points to a corect wsdl whcih will load if tried from the browser directly, also I managed to add this wsdl as a reference in a .Net project

I tried also to create a webservice client in JBDS by using File / New / web Service Client wizard, that one also fails to do the job to the end.
