Use the RequestDispatcher's include function.
There are several ways to get the RequestDispatcher (slight difference
depending on where u get it from) but the way that I usually do it is:
request.getRequestDispatcher("fileIWantToInclude.jsp").include(
request, response );
Look for a NullPointerException which will be thrown by the above if the
file does not exist.
