Are you trying to use the appengine sdk from client code that is compiled into javascript? That won't work.
You'll need to make requests from the client to the server, and have the code on the server call the appengine sdk. Have a read of the following links: - http://code.google.com/webtoolkit/doc/latest/tutorial/RPC.html - http://code.google.com/webtoolkit/doc/latest/tutorial/clientserver.html A best practice way of doing this is using the command pattern<http://en.wikipedia.org/wiki/Command_pattern>, you might want to check out a framework to help you with this. I currently contribute to gwt-platform, and have used gwt-dispatch in the past. - http://code.google.com/p/gwt-platform/wiki/GettingStartedDispatch - http://code.google.com/p/gwt-dispatch/wiki/GettingStarted Cheers, Brendan -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
