Whenever I try to redirect to a certain page using this dispatch method that is called from my doGet method, I get the following exception. I have no idea why!

account controller servlet

protected void dispatch(HttpServletRequest request,
            HttpServletResponse response, String page)
            throws javax.servlet.ServletException, java.io.IOException {
        RequestDispatcher dispatcher = getServletContext()
                .getRequestDispatcher(page);
        try {
            dispatcher.forward(request, response);
        } catch (java.lang.NullPointerException e) {
            System.out.println("NullPointerException: attribute expected in view");
        }
    }
