title: Liferay: Can't see the deployed portlet
body: <p>I develop a sample JSF portlet for the Liferay portal. 
  After I had deployed it (no errors in the console and the .war file from the <em>liferay/deploy</em> directory is removed to the <em>liferay/tomcat/webapps</em> and is exploded). I tried to add this portlet to a new page via Liferay's admin console. The problem is - I can't find my portlet. 
  I've tried to deploy an example portlet from Liferay's site and everything was ok. All the .xml files are completely the same as in the example.</p>
  
  <p>Could somebody help me?</p>
  
  <p>UPDATE: I've found listenerStart error in tomcat output. What can it be?</p>
