ServletExec and RequestDispatcher

[Sair Legge]

I'm using ServletExec to process my Servlets/JSPs and am having problems using the following code to forward a request on:
RequestDispatcher dispatcher = request.getRequestDispatcher(address);
dispatcher.forward(request, response);
If I put the servlet class in the default servlets directory it works no problem, however if I configure a Web Application and put the servlet class in the WEB-INF\classes directory it throws a NullPointerException as the getRequestDispatcher method returns NULL.
Any ideas why it works as a 'stand-alone' servlet but not as part of an app?

Try checking the servlet mapping in in the web.xml file. Also chk the path u are specifying while constructing the RequestDispatcher.
