title: Is it possible to access files beyond WEB-INF folder in dev mode of GAE (java.security.AccessControlException: access denied)?
body: <p>Is it possible to access files beyond WEB-INF folder in Google App Engine's development server ? Maybe I can somehow force GAE dev server to do not block external connections/file access ?</p>
  
  <p>I'm trying to create Java version of <a href="http://gae-sqlite.googlecode.com" rel="nofollow">gae-sqlite</a>. But I can't access external sql server (mysql or h2db) due to <code>access denied</code> exceptions.</p>
