    >> Cannot set header. Response already committed.

          It happens before you try to "sendRedirect" or requestDispatcher.forward(..), you already send some texts to response output stream and it is flushed(buffer is full) or committed.
          Solution: Before you possibly "redirect" or "forward" , don't write anything out, write data utill you decide if you want to "redirect" or "forward" or contiue to write out the data in current response output stream.

         Hope it helps :)
