Hi to ALL
Friends i have some problem regarding RequestDispatcher

on the base of code i am forwarding my message to another jsp page from servlet
and i use code

req.setAttribute("message","No Record Found");
RequestDispatcher rd = req.getRequestDispatcher("../Error.jsp");
rd.forward(req,res);

but when i run servlet this give Java.lang.NullPointerException on line rd.forward(req,res);
ie show rd is null;

it happens only first time and when i refresh the page it gives me proper output.

Please tell me why is this giving NullPointerException at first time and how could i prevent it.

Try this.

RequestDispatcher rd = req.getRequestDispatcher("/Error.jsp");
rd.forward(req,res);
