session value in java

[sinhak.alok]

First, I send user id from jsp page to servlet. That value received
on servlet page like this :-
String username = request.getParameter("user");
Then creating the session true on servlet like this:-
HttpSession session = request.getSession(true);
After that I set the value using setAttribute method
session.setAttribute("user_id", username);
When I receiving session value using getAttribute method it display
null on jsp page. my code is:-
String usercode = (String) session.getAttribute("user_id");
I am using Oracle JDeveloper 10g Relaese 2 as Editor.

When I receiving session value using getAttribute method it display
null on jsp page. my code is:-
String usercode = (String) session.getAttribute("user_id");

Eschew scriptlet in JSPs. Consider using ${ user_id } instead.

I have seen firewall software prevent establishment of a session, although I'm
not sure how it did that. Updated firewall policies fixed that problem.

You don't show the part that displays the value. The one line of code you
posted for session retrieval doesn't show the source of the problem.

Are you able to see the session variable through the debugger?
