i want to hide the welcome.jsp page. If we try to access welcome.jsp directly from browser(before doing the login) it should create new session and go to the login page. that is what i want to do. here is my code.



it goes to else part only. and print "welcome null"

You shouldn't be testing for the session itself. Rather, test for a scoped variable (attribute) that you place in the session upon login.

Be aware that JSP automatically creates a session, unless you specifically put this in the page:

<%@ page session="false" %>

thats exactly what the answers mean!

you dont check for pre-existing session but a scope variable within.. if it's not existing.. your pre-existing session isn't either.....

Then you need to add the line I mentioned to the JSP.
