title: Google App Engine Warfile Directory Structure
body: <p>I just installed the Google Eclipse plugin and created my first test Web Application Project (using both GWT and GAE SDKs). The plugin autogenerated a project that had a <code>war/</code> directory in it that had some peculiar subdirectories and files in it. An online search for many of these only returned other similar autogenerations of them but without any real explanation of what they are, or what they do:</p>
  
  <ul>
  <li><code>war/WEB-INF/deploy/&lt;myapp&gt;/rpcPolicyManifest/**</code></li>
  <li><code>war/WEB-INF/deploy/&lt;myapp&gt;/symbolMaps/**</code></li>
  <li><code>war/&lt;myapp&gt;/symbolmanifest.json</code></li>
  <li><code>gwt-unitCache/**</code></li>
  </ul>
  
  <p>I'm also a litte confused about what the proper structure should be for a GWT WAR that is going to be deployed to GAE. What content should be packaged under <code>war/WEB-INF/</code>? What content should be packaged under the <code>war/</code> root? Any other special considerations for GWT/GAE WARs? Thanks in advance!</p>
