Getting error in implementing Spring MVC

[Honey Agarwal]

Hi,

I am new to Spring MVC and trying to implement a form page. Here is the code:

Hello.jsp:

 <form:form modelAttribute="userDomain" method="post" action="hello">
    <table>
        <tr>
            <td><form:label path="emailId">First Name</form:label></td>
            <td><form:input path="emailId" /></td>
        </tr>
        <tr>
            <td><form:label path="name">Last Name</form:label></td>
            <td><form:input path="name" /></td>
        </tr>


        <tr>
            <td colspan="2"><input type="submit" value="Go" /></td>
        </tr>
    </table>
</form:form>

Controller:

 @Controller
  public class HelloWorldController {

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

 @RequestMapping(value = "/hello", method = RequestMethod.POST)
  public ModelAndView hi() {
  // String message = "Hi " + name + "!";

  ModelAndView mav = new ModelAndView("hello");
    mav.addObject("userDomain",new UserDomain());
    return mav;
  }

  @ModelAttribute("userDomain")
  public UserDomain getUserDomain(){
  return new UserDomain();
    }

 }

But I am getting the error:


SEVERE: Servlet.service() for servlet [jsp] in context with path [/ChatBooster] threw exception [java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'userDomain' available as request attribute] with root cause java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'userDomain' available as request attribute at org.springframework.web.servlet.support.BindStatus.(BindStatus.java:141) at org.springframework.web.servlet.tags.form.AbstractDataBoundFormElementTag.getBindStatus(AbstractDataBoundFormElementTag.java:174) at org.springframework.web.servlet.tags.form.AbstractDataBoundFormElementTag.getPropertyPath(AbstractDataBoundFormElementTag.java:194)


What can be the issue?
