[appengine-java] Re: problem with using session.getAttribute()
Guys I had a similar issue when I was using JSF. What I found in my case was if I set an attribute (say dummy string "key" "value") on every request, the other values stored in the session are maintained. If I dont do that, on every subsequent request in which nothing is saved in the session, other saved values are dropped (this happens only on appspot not dev server). This all started when I tried debugging my code on appspot. But I still can't comprehend why this is happening. Try the approach and let me know if it works in your case as well.

[appengine-java] Re: JSF 2.0.1 java.lang.ClassNotFoundException: void
I had a similar issue. The way I fixed it was to configure state saving to client rather than server. For details check my blog http://consultingblogs.emc.com/jaddy/archive/2009/11/20/jsf2-in-google-app-engine.aspx Let me know if this fixes your problem.
