Web application without entry points in app engine?

I have only request/response handlers(servlets) for my GAE app. No front ends/entry points are needed. However I can't build/debug my app (in eclipse) without atleast an entry point class. Are entrypoint modules must for gae app? If not, how can I solve this problem?

Solution

  • No, GWT modules are not needed for App Engine.

    Yes, they are needed for GWT. If you have a GWT app, then:

    1. You need a html host page. You need to have this page on your App Engine instance.
    2. You need at least one GWT module with one entry point class. GWT client-side classes are compiled to javascript on your developers machine, then uploaded as JS files to App Engine.
    3. If you use GWT-RPC (or RequestFactory) then you'll also need server-side java classes on your App Engine.
