title: Print stacktrace directly in errorpage?
body: <p>I'd like to print the stacktrace directly within the error page (at least a few lines).</p>
  
  <p>In JSP it would be something like this:</p>
  
  <pre><code>&lt;%@ page isErrorPage="true" %&gt;
  &lt;% exception.printStackTrace(); %&gt;
  </code></pre>
  
  <p>How can I do similar with JSF2 in my Facelets page? Any chance without a backing bean?</p>
