I have an controller that returns JSON. It takes a form, which validates itself via spring annotations. I can get FieldError list from BindingResult, but they don't contain the text that a JSP would display in the tag. How can I get the error text to send back in JSON?

@RequestMapping(method = RequestMethod.POST)
public
@ResponseBody
JSONResponse submit(@Valid AnswerForm answerForm, BindingResult result, Model model, HttpServletRequest request, HttpServletResponse response) {

    if (result.hasErrors()) {
        response.setStatus(HttpServletResponse.SC_BAD_REQUEST);
        JSONResponse r = new JSONResponse();
        r.setStatus(JSONResponseStatus.ERROR);
        //HOW DO I GET ERROR MESSAGES OUT OF BindingResult??? 
    } else {
        JSONResponse r = new JSONResponse();
        r.setStatus(JSONResponseStatus.OK);
        return r;
    }

}

JSONREsponse class is just a POJO

public class JSONResponse implements Serializable {
    private JSONResponseStatus status;
    private String error;
    private Map<String,String> errors;
    private Map<String,Object> data;

...getters and setters...
}

Calling BindingResult.getAllErrors() returns an array of FieldError objects, but it doesn't have the actual errors.
