problem using org.apache.jetspeed.util.servlet.EcsServletElement

[Stan Pinte <st...@wanadoo.be>]

hello,

I am trying to use a 
org.apache.jetspeed.portal.portlets.ServletInvokerPortlet to invoke one of 
my servlets.

I have managed to have that servle invoked by the ServletInvokerPortlet, 
but I am getting this exception, just after having called

request.getRequestDispatcher("result.jsp").include(request, response);

in my servlet.

The exception is the following ( I am not including the full stacktrace, 
you know why ;-) )

Would any servlet expert know why? Do I have to respect some guidelines in 
the usage of the RequestDispatchere forward() and include()
methods?

Thanks a lot,

Stan.
