Hi,

doPost/doGet throw ServletException. I think the problem lies in that you a=
re wrapping your exception but this does not translate to the exception act=
ually being "of class" UserNotFoundException. You'd need to actually throw =
your own exception which could extend ServletException for example.

Cheers, Allistair.
