A simple project (where the JSF2 framework initializes and a default page is
displayed) is available at Google Code: http://code.google.com/p/jsf2template/.
This is the source code for the application I wrote developing the tutorial
for configuring a JSF 2 project to run on Google App Engine -
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

Let me know if this fixes your problem.
