Error at RequestDispactch..

Hi,
I am trying to deploy project on www.webappcabaret.com site.
So far it's working fine.I am able to redirect from html to html and html to servlet .But when I do from servlet to html file
getting error as below.
It is giving error at
out.println("Before dispatch"+"<BR>");
RequestDispatcher RD =getServletContext().getRequestDispatcher ("http://www.webappcabaret.com/padmashree/Login.html");
RD.forward(req,res);
out.println("After Dispatch");
it prints Before dispatch and then Error :500

Error: 500
Location: /padmashree/Registration

I have not used tomcat and Apache server before.Though it's working fine on my PC (with JRUN).
Thanks

i can get to a form, without any exceptions!
do you need me to do something there to get the
exception?
Also, if you have a guest accnt setup, pl.
send me the login info so i can try! Not another
accnt again....

Hi all ,
My problem solved. I had given absolute path in request dispatch method so it was giving error.
Thanks,
