Description

I wrote to test class to test a servlet which finally does a forward to a JSP.
When I call the forward method on the RequestDispatcher, I get the following
error. It looks like
org.apache.cactus.server.RequestDispatcherWrapper.dispatch179_forward is trying
to cast the WebAppRequestDispatcher to something it shouldn't. Here is the
stack trace ...
