Hi Ana, It worked now, thanks again ! I had to flatten my WSDL (copy the XSD that I imported into the file itself) and rename the class that implemented the endpoint to make jbossws understand it, but now I end up in the errorhandler on schema validation errors. A remaining problem, that for now makes the feature not so useful: if I throw an exception in my handler, nothing happens. As in: the client gets back nothing (nope, nada, zero bytes) instead of a SOAP fault I was expecting. Cheers, Luc.
