As the exception message says, the "writer is already being used" ;-)
The JSP processor uses response.getWriter() to get a PrintWriter when it
receives the request. When you include the same response object is used
and when you have called getWriter you can not call getOutputStream on
the same response object. I'm not sure why you create your own PrintWriter
like you do in your servlet, but try
PrintWriter out = resp.getWriter();
instead. That should solve the problem.
