Sorry, The examples I sent you were for testing just servlet chaining.
This itself appears to be broken.
The problem I see is the the Request parameters are available only to the
first servlet in the chain. The second servlet
does not get the request parameters. On further testing I saw that the
query string is preserved in the second servlet but the
getParameter() call does not work.
In my original application I am actually using mime types to chain servlets.
The chaining itself works in the sense the correct servlet is called based
on the content type set. However if I try to acces the parameters in the
second servlet I do not see them I will try to rig up a test case and send
it to you tomorrow.
Thanks
