FrontController Endless Loop

I am trying to implement the Front Controller pattern for all requests through my application.
In web.xml:

This is basically just what Sun has on their site for implementing this pattern.
And in the FrontController servlet I am trying to forward to jsp pages using the RequestDispatcher.forward method. I have tried it with both the ServletRequest and ServletContext objects. When I call a page it overflows the stack because the servlet keeps calling itself. What am I doing wrong?

you wrote <url-pattern>*</url-pattern>
then all requsts are gonna send to FC servlet
include your *.jsp forwarding request.
one possible way to solve this problem is,
change the url-pattern in web.xml(ex. *.go).
then *.go url will be requested to FC,
and inside FC, forwarding to *.jsp will work okay.
I agree. Here's the link:
