Define bean in bean definition file for Handler class. when any exception is thrown in a program ,resolveException method is called.

  public class Handler
        implements HandlerExceptionResolver
    {

        public Handler()
        {
        }

        public ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
        {
            if(ex instanceof ErrorType1Exception))
            {
                 ModelAndView test = new ModelAndView("errorpage1jsppage");
return test;
            } else
            if(ex instanceof ErrorType2Exception))
            {
                 ModelAndView test1 = new ModelAndView("errorpage2jsppage");
return test1
            }
        }
    }
