Looking for substantial open source GWT/App-Engine project to use as reference

Question

I'm working on GAE-J/GWT app, wherein a desktop app connects to the GAE-J component, and there is also a web-app component whose front-end is written in GWT, and the GAE-J backend supports both the desktop app and the web app.

I have a good amount of experience with writing pure server code and desktop code, but not so much on the web-app side of things. So I'm looking to study some good sophisticated open source code to see how other's have done things, but I can't find much open source GWT and/or GAE-J stuff, other than frameworks. Does anyone know of any good projects out there?

Answer 1

There isn't any GWT in it (yet?) but Partychat (Google Code Project) is a moderately-sophisticated open-source Java App Engine app that simulates multi-user chatrooms using the XMPP service.

I'm sure there are more sophisticated apps out there, and some that include a GWT component, but I figured I'd take the chance to self-promote when it's given :)

Answer 3

GWT tagged open-source projects on google code hosting.

Answer 4

I've written a little app called SixFixMix that uses the following stack: GWT, GIN, dyuproject (for OpenID), gwt-mobile-webkit (for HTML5 Geolocation), gwt-google-apis (for Maps), gwt-log, gwt-presenter, gwt-dispatch, Objectify, and GAEJ. Good luck!
