Check the line number reprted for your exception to see if the exception is thrown in the servlet or on the JSP. Debug the code or use some simple println statements to pinopoint the exact line and variable that is causing the null pointer.

Probably at some point you try to use some Object, which you have declared but not yet defined, however without seeing the code, we won't be able to help you any further.
