I need to maintain the login user-id in my application... For each database interaction I need to send the user-id.. I am maintaining the user-id and other info in a bean and I put that bean in a session variable..
But some times the session will automatically closed and gives nullPointerException when I try to call the session variable.
I am also trying to give the session max age in the web.xml <session-config> <session-timeout>0</session-timeout> </session-config>
But this is also not solve my problem..
Right now i am using RAD to develop my application... When i run my application in the local system this session problem expires.
please give my any suggestion to solve the problem..
