Question

I am teaching myself Spring Form tags, and have run into what is probably a simple error that I haven’t been able to solve. I get the following error when I launch this app in a browser:

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

I’ve tried most of the fixes that came up in a Google search to no avail. Can someone spot where I went wrong? Below are the relevant components. Thanks very much.

Controller:

@Controller
@RequestMapping("/registration")
public class LoginController {

    @RequestMapping(method = RequestMethod.GET)
    public String setupForm(ModelMap model) {
        Registration registration = new Registration();
        model.addAttribute("registration", registration);
        return "index";

    }


    @RequestMapping(method = RequestMethod.POST)
    public String onSubmit(@ModelAttribute("registration") Registration registration, Map model) {
        return "success";
    }
}

JSP (/index.jsp):

        <form:form commandName="index">
        <table border="0" cellspacing="12">
            <tr>
                <td>
                    <form:input path="email"/>
                </td>
            </tr>

            <tr>
                <td>
                    <form:password path="password"/>
                </td>
            </tr>

            <tr>
                <td>
                    <input type="submit" value="Submit"/>
                </td>
            </tr>
        </table>
    </form:form>

Command Object (Registration.java) :

public class Registration {
    private String password;
    private String email;
    // getters,setters

Answer 1

In your index page correct the following and try

<form:form commandName="index"> to <form:form commandName="registration">

You can also do it like this if the above does not work

<form:form modelAttribute="registration" commandName="registration">

Thanks
