Example Sample Code
@RequestMapping(value = "/add", method = RequestMethod.POST)
public ModelAndView addEmployee(Model model, EmpTO empTO, BindingResult bindingResult){
    try {
    } catch (Exception e) {
        if (e instanceof InvException) {
            model.addAttribute("error", ((InvException) e).getError());
        } else {
            model.addAttribute("error", PresentationUtil.handleApplicationRuntimeError(e));
        return new ModelAndView("emp/save");
    empTO = new EmpTO();
    return new ModelAndView("emp/home");


1. Is the above is the correct approach?
2. Can we store the error code and description in a DB table or hard-coded string and let UI handles the error codes?
3. Is this is a standard industry practice?
