Telling which resource was not found on a 404 page

Question

Hello.
          I thought that it would be nice to have a 404 page that tells the user what
          he was trying to get but wasn't there.
          Full of hope I constructed the file error_404.jsp containing this:
          The requested document
          <%
          if ( null != request ) {
          out.println("<i>" + request.getRequestURI() + "</i>");
          %>
          could not be found.
          Unfortunately, this only tells the user that error_404.jsp could not be
          found, and that's not even true! =)
          How can I find out which resource was originally requested by the browser?
          Regards,
          Björn

Hello,
It looks like the classloader used to load TopLink cannot find your jar or sessions.xml. Have you tried using the SessionManager api that takes in a specific classloader, for instance:
(DatabaseSession)SessionManager.getManager().getSession("default", yourPersistenctClass.class.getClassLoader() );
