GWT + GAE python: frameworks for COMET & RPC

Question

Let\'s say I want to use Google GWT on the client side and Google AppEngine Python on the server side. Furthermore, I want to be able to use RPC calls to the server as well

Answer 1

App Engine doesn't currently support comet, because it doesn't support hanging-GETs (eg, long-running requests). If you want to do comet, you'll have to use an external service, or wait for Comet support in App Engine.
