    @RequestMapping(value="/check", method=RequestMethod.POST)
   public String check(ServletRequest theRequest, ServletResponse theResponse) {
       HttpServletRequest request = (HttpServletRequest) theRequest;
       HttpServletResponse response = (HttpServletResponse) theResponse;

       ApplicationContext context = WebApplicationContextUtils.getWebApplicationContext(request.getSession().getServletContext());
       CaptchaService captchaService = (CaptchaService) context.getBean("captchaService");


       try {
           String captchaID = request.getSession().getId();
           logger.info("captchaID:"+captchaID);
           String challengeResponse = request.getParameter("j_captcha");
           logger.info("challengeResponse:"+challengeResponse);
           boolean bRet = captchaService.validateResponseForID(captchaID, challengeResponse);
           if( bRet )
               return "home";
           else
               return "login";
       } catch (CaptchaServiceException e) {
           logger.error(e.getMessage(), e);
           return "login";
       }
   }
