    @Override
    public ModelAndView handleRequest(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {

        ModelAndView mv = new ModelAndView(view);
        
        mv.addObject("name", "moon");
        return mv;
    }

String get_hello = request.getAttribute("name").toString();

response.getWriter().write(get_hello);

%>
