Rajat, I've had that type of disconnect problem using Hibernate (a product roughly like Ibatis). My problem was one of the DBCP settings: minIdle. MySQL wasn't seeing any activity on some pool connections overnight, so it was disconnecting them. Lowering the minIdle setting seemed to cause DBCP to test each pool connection by performing a simple select automatically. The query seems to be a non-table select, along the lines of a 'select 1+1;'. That allowed MySQL to keep each connection active and not disconnect any overnight after being idle for hours.
