HI, I have a little GWT app that I tried to deploy to GAE the first time. The clientside app works fine so far, but when executing a RPC request (which works on my local machine), there are exceptions about "class not found". Do I have to make any changes for RPC with GAE? Or may I have forgotten anything?
