Subject RE: forward error
Date Thu, 04 Sep 2003 19:50:56 GMT

Both errors are fairly clear and essentially the same.  You can't
forward or redirect a response that's been committed, i.e. written to.
If you're going to forward or redirect a response, you must do so before
writing to the response.  You can read the JavaDoc for
HttpServletResponse#sendRedirect and RequestDispatcher#forward.
