OK, Now it re-directing,
but the Session that I created in the servlet doesn't want to give me any
values.
When I call userSession.getValue("userName") it throws a
NullPointerException.
Can you pass a session from a servlet to an xml page.

Anthony,

Why do I lose my session context when doing a
response.sendRedirect()? Answered by: Jayson Falkner
Some browsers do not accept and handle cookies properly. When this happens
the jspsessionid cookie may get lost and a new session will be started for
the redirected browser. The common solution to this problem is to encode
the URL before sending the response. Use
response.sendRedirect(response.encodeRedirectURL("/example.jsp")), and
substitute the correct resource for the redirect.

Richard
