But before saving I check if the id is a certain range. If the id is not withing the range, I need to show http://stackoverflow.com/questions/22664533/how-to-show-error-message-on-same-page-in-spring-mvc message on the same page that "The id selected is out of Range, please select another id within range". I found samples on internet where I can redirect to failure jsp in case anything goes wrong. But how to do it in my case? @RequestMapping(value = "/sendMessage") public String sendMessage(@ModelAttribute("message") Message message, final HttpServletRequest request) { boolean check = userLoginService.checkForRange(message.getUserLogin()); if(!check){ return ""; //What Should I do here?????? } Thanks in advance. spring jsp spring-mvc share|improve this question asked Mar 26 '14 at 14:45 romhail 1472319 add a comment| 2 Answers 2 active oldest votes up vote 7 down vote accepted A simple approach would be to add your error message as a model attribute. @RequestMapping(value = "/sendMessage") public String sendMessage(@ModelAttribute("message") Message message, final HttpServletRequest request, Model model) { boolean check = userLoginService.checkForRange(message.getUserLogin()); if(!check){ model.addAttribute("error", "The id selected is out of Range, please select another id within range"); return "yourFormViewName"; } } Then your jsp can display the "error" attribute if it exists.
