consuming SOAP web serives in google app engine and GWT

I am writing a web application in GWT, I am trying to interact with a SOAP web ser开发者_如何学Govice. I know how to do it in regular java environment using the JAX-WS library, but GAE (Google App Engine) does not support it.

see http://groups.google.com/group/google-appengine-java/web/will-it-play-in-app-engine

is there a way of consuming a wsdl based web service (ebay web service for example) using GWT+GAE?

Thanks!

Apparently, it seems to work with the AxiomSoapMessageFactory from Spring WS.

There is a detailed article named Exposing SOAP Service on GAE. I assume it might be possible to consume one WS following the same technology stack Using Spring Web Services on the Client.
