Hi,
this error comes up when the destination serlvet throws an exception other than ServletException!
Its a standard tomcat bug!

-->From apache.org:
When a forwarded servlet throws an exception other than ServletException or
IOException, the thrown exception is lost. This is due to the line:
throw new ServletException(sm.getString("dispatcher.forwardException", t));
(found in org/apache/tomcat/facade/RequestDispatcherImpl.java:210)
the earlier catched t is here not passed into the constructor of
ServletException but into getString.
To reproduce construct a servlet that throws an Exception (other than
ServletException and IOException) and another servlet that forwards to it. You
will get just a forwardException (if you have the proper locale strings
installed!) but the originally thrown exception will get lost forever.
