Help: diff between tomcat 4.0 and tomcat 4.0.1

[Nirmal Rajarathnam <ni...@fresher.com>]

My webapp which was working fine on tomcat 4.0 after I upgraded to 
tomcat 4.0.1 has not worked since. Can someone tell me what is the 
difference between both. I am running the server on Win 2000 with JDK 
1.4 beta 3 on a stand-alone mode. The error seems to be where I call 
getServletContext().getRequestDespatcher(location).forward(request, 
response); (the last line in the error message dump)

Can someone help, point me the mistake.

Thanks,
Nirmal R.
