HI we are getting the following exception when tried to connect with the DB server from Applcation Server
at beginning after the restart of the App server it worked fine but again after one day duration we are again facing the same problem

CAN ANYBODY SUGGEST ME THE WAY TO TRACE THE PROBLEM
we have used EJB 3.0 Entity manager concept for intreaction with the Data Base

Immediately after login into the application it checks for the validation of the user in the DB and we have observed it has been failed in the first interaction with the Data Base
