Servlet Session creation after committing it.

I have a servlet whose session expires after 10 minutes. Now if the user hits the browser after session expires i want to do certain processing and then recreate a new session. But i get

"java.lang.IllegalStateException: Cannot create a session after the response has been committed"

Any advice on how to solve this problem. Also any suggestions on what else i could do with a request which comes after session expiration?
