Include a javascript utility function inside your JSP and ping the server every 31 minutes. The above mentioned utility function should be using setTimeout() JS function internally.

setTimeout ( "checkServerSession()",  /* intervalInMilliSeconds */ 31000);

checkServerSession()

is a regular JS function which may fire HTTP requests. If the request is successful session exists otherwise show the prompt to the user.
