Hi , I have a request for gae-j, is it not a good idea to have an 1) appengine simulator as a java eclipse plugin
or sandbox account for testing app on the server , so that it is easier to debug ... i have come across numerous scenario where thing work locally and dont work on app engine, it has been a big turnoff for me to use appengine with thirdparty libs/frameworks is it on the road map?
