title: Deploy a Java app to GAE
body: <p>I tried to deploy a pushbot on GAE by using: <a href="http://code.google.com/p/partychapp/source/browse/pushbot" rel="nofollow">http://code.google.com/p/partychapp/source/browse/pushbot</a> source code.</p>
  
  <p>I can see the bot online, but it never answer my command, did I miss something?</p>
  
  <p>The error like:</p>
