hi, i have some doubts on the validation message not standardize on the statusbar not sure


whether i code the correct way or the methods i pass is correct.

for example: if empty fields submit, the validation error message will appear but however when i come to error message reply form the controller the error message is not standard as the empty fields submit.

therefore need some helps on how to edit it to standard the message.


currently my html page are as follow


HTML Code:
html><head>    <title>Hello Ext</title>    <link rel="stylesheet" type="text/css" href="extjs/resources/css/ext-all.css">    <link rel="stylesheet" type="text/css" 
href="extjs/examples/ux/statusbar/css/statusbar.css">    <script type="text/javascript" src="extjs/ext-all.js"></script>    <script type="text/javascript">      var statusbarmsg = "${status}";      if (statusbarmsg == null || statusbarmsg =="")          statusbarmsg = "Form Ready";    </script>    <script type="text/javascript" src="app.js"></script>  <script type="text/javascript" src="extjs/examples/ux/statusbar/StatusBar.js"></script></head><body></body></html>

my login controller is as below




Code:

package login.controller;

import java.servlet.http.HttpServletResponse;
import java.servlet.http.HttpSession;

import org.springframework.validation.Validator;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import org.springframework.web.servlet.view.RedirectView;






public class LoginFormController extends SimpleFormController {


@Override
protected ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, Object command, BindException errors) throws Exception {
    User login = (User) command;
    String loginId = login.getLoginId();
    String pwd = login.getPassword();
    
    if (loginId == null || loginId.length() == 0) {
        request.setAttribute("wrongUser",loginId);
        ModelAndView mav = ModelAndView("login.htm");
        mav.addObject("sbWin","Enter userid");
        return mav;
    }
    else if (pwd == null || pwd.length() == 0) {
        request.setAttribute("wrongUser",loginId);
        ModelAndView mav = ModelAndView("login.htm");
        mav.addObject("sbWin","Enter password");
        return mav;
    }
    else {
        
        if (loginId="admin" && pwd ="123"){
            HttpSession session = request.getSession();
            session - request.getSession(true);
            request.setAttribute("loggedAccount",session.getId());
            ModelAndView mav = ModelAndView("user.htm");
            mav.addObject("loginId", loginId);
            return mav;
        }
        else {
