The exception is often caused by using a session which is already closed. Your other question also points to the fact that you may have to reconsider your connection and session usage.

Because there is not much information in your questions, it is hard to suggest an improvement.

Thanks for reply jan .Can u please provide me ur mail id,so that i can send u DataConfiguration and some more logs
I'd rather not. That's what this site is for, and my time is not free. You should do some research yourself, try to isolate the problem, and post the results on this site. If you invest some time to find out what the problem is, and take some time to describe the problem properly, there are a lot of people on StackOverflow willing to help you.
