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

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

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";
}

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.
