ok, I initiate a session, use my application continuously and view different pages. Randomly at some point the page just hangs and in the catalina.out i get "NullPointer error" pointing to the line which is "request.getSession..." . So this is the problem.

Hi Shaik, Probabaly you can re-check your program and also if you have any session time-out very shortly then if your not accessing the resource within that stipulated time, you might get this.
