Spring 3 MVC error: Neither BindingResult nor plain target object for bean name 'user' available

Question

I know this issue might have been addressed elsewhere but I'm unable to find a satisfactory solution to my problem. Btw, I'm working with spring 3.0.2

Login.jsp

<form:form id="_LoginForm" name="LoginForm" modelAttribute="user" action="login" method="POST">
    <form:input path="username" value=""/>
    <form:input path="password" value=""/>
    <input type="submit" value="Submit"/>

LoginController.java

@RequestMapping(value="login", method=RequestMethod.POST)
public String login(@ModelAttribute("user") User user, BindingResult result) {
    System.out.println("recd request");
    return null;
}

When I try to access the login.jsp page, I get the following error:

java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'user' available as request attribute

Can you please provide your RequestMethod.GET method in the controller? Just want to make sure you are adding the modelAttribute in the GET method as well.

Are suggesting to add a sort of setup method which puts the "user" attribute into the model map and then redirect to the login page? – Deepak Marur Oct 20 '11 at 02:17

I added the the following method to make this work, though I feel there must be a better way to get this working without having to write a setup method everytime.

applicationContext.xml

<mvc:view-controller path="/" view-name="index" />

index.jsp

<jsp:forward page="index.action"/>

LoginController.java

@RequestMapping(value="index.action", method=RequestMethod.GET)
public String setupLogin(Map<String, Object> modelMap) {        
    modelMap.put("user", new User());
    return "Login";
}
