I've been working on this problem for a long time within the gwt- platform project: http://code.google.com/p/gwt-platform/issues/detail?id=1
I've gotten very far (i.e. I can make it work in development mode) but I ran into a very annoying issue with the urlfetch API of AppEngine: http://code.google.com/p/googleappengine/issues/detail?id=3602 I don't know if this relates to your problem, but you may want to read the forum thread mentioned in the above issue for more details.
