@requestmapping and ModelAndView

Hi help me please with Spring RequestMapping. I have page like this:

<form action="/add_photo" enctype="multipart/form-data" method="POST">
                Photo: <input type="file" name="photo">
                <input type="submit" />
     </form>

and controller like this:

@Controller
@RequestMapping("/")
public class MyController {

    private Map<Long, byte[]> photos = new HashMap<>();


    @RequestMapping("/")
    public String onIndex() {
        return "index";
    }

    @RequestMapping(value = "/add_photo", method = RequestMethod.POST)
    public ModelAndView onAddPhoto(@RequestParam MultipartFile photo) {
        if (photo.isEmpty()) {
            throw new PhotoErrorException();            
        }

        try {
            long id = System.currentTimeMillis();
            photos.put(id, photo.getBytes());

            ModelAndView model = new ModelAndView();
            model.addObject("photo_id", id);
            model.setViewName("result");
            return model;
        } catch (IOException e) {
            throw new PhotoErrorException();
        }
    }
}

method "onIndex" is working but onAddPhoto seems not and when I click button whith URL "/add_photo" it gives me 404 instead page "result"

Use pageContext in your jsp page as:

<form action="${pageContext.request.contextPath}/add_photo" enctype="multipart/form-data" method="POST">
Photo: <input type="file" name="photo">
            <input type="submit" />
 </form>
