Error Messages are not displayed in JSP

[Sasi_111]

Hi,

I'm new to Spring. I have written a simple example by using the MultiActionController. Once the user submits the login page, im validating the userName and password in validator class. Im calling validator class validate method from a controller. Validations works perfectly and im able to print number of errors in controller, but once its directed to login JSP, its not showing the error messages on the screen. I will appreciate If somebody help me in this regard..thanks....

Controller Method :

public ModelAndView onClickLogin(HttpServletRequest request,
HttpServletResponse response, LoginCommand loginCommand)
throws Exception {
/*
* BindException errors = new BindException(loginCommand,
* "loginCommand"); loginFormValidator.validate(loginCommand, errors);
*/

// this.preBind(request, loginCommand);
ServletRequestDataBinder binder = createBinder(request, loginCommand);
binder.bind(request);

BindException errors = new BindException(binder.getBindingResult());
if (loginFormValidator.supports(loginCommand.getClass ())) {
ValidationUtils.invokeValidator(loginFormValidator , loginCommand,
errors);
}

if (errors.hasErrors()) {
System.out.println("--------it has some errors21"
+ errors.getErrorCount());
ModelAndView modelAndView = new ModelAndView("login");
modelAndView.addObject("loginCommand", loginCommand);
modelAndView.addAllObjects(errors.getModel());
return modelAndView;
}
// LoginCommand loginCommand = (LoginCommand) command;
System.out.println("Inside the onClickLogin Method");
authenticationService.authenticate(loginCommand);
AccountDetail accountdetail = accountServices
.getAccountSummary(loginCommand.getUserId());
ModelAndView modelAndView = new ModelAndView("accountdetail");
modelAndView.addObject("accountdetail", accountdetail);
return modelAndView;
}


Validator Class

public class LoginFormValidator implements Validator {

public void validate(Object command, Errors errors) {
LoginCommand loginCommand = (LoginCommand) command;

// checking userName or password is empty
if ("".equals(loginCommand.getUserId().trim())) {
errors.rejectValue("userId", "error.userId.empty","UserId should not be empty");
}
if ("".equals(loginCommand.getPassword().trim())) {
errors.rejectValue("password", "error.password.empty", "Password should not be empty");
}
}

public boolean supports(Class clazz) {

return LoginCommand.class.isAssignableFrom(clazz);
}

}

<form:form method="post" commandName="loginCommand" >
<spring:bind path="loginCommand">
