Besky,
Thanks, that is a good thought , no we are not doing any backup right now, other pages which access the databse are working fine
but one thing i over-ride the session creation in that jsp page
i set session=false in the "page" attribute and i create
the session object by myself like
HttpSession session = request.getSession(true)
is that any problem with session object???
or is there any objects created in the jspinit() method get carbage collected after some times???

You don't say exactly where the NullPointerException is coming from, I should think that would be the first thing to investigate. you should be dumping a StackTrace for that exception - either have an errorPage designated for your JSP or try-catch blocks for the code.
