Getting IllegalStateException while running a simple Spring MVC application

[pankaj1907]

Hi,

I am new to Spring MVC. I have created an application. Here's my code.

<form:form method="post" action="save.html" commandName="user">

	
		<table>
			<tr>
				<td><form:label path="loginName">
						<s:message code="nameLabel" />
					</form:label></td>
				<td><form:input path="loginName" /></td>
			</tr>
			<tr>
				<td><form:label path="password">
						<s:message code="passwordLabel" />
					</form:label></td>
				<td><form:input path="password" /></td>
			</tr>
			<tr>
				<td><form:label path="role">
						<s:message code="roleLabel" />
					</form:label></td>
				<td><form:input path="role" /></td>
			</tr>
			
			<tr>
				<td colspan="2"><input type="submit"
					value="<s:message code="login"/>" /></td>
			</tr>
		</table>
	</form:form>

UserController.java

@Controller
public class UserController {

@RequestMapping(value = "/save", method = RequestMethod.POST)
    public String saveUser(@ModelAttribute("user") User user, BindingResult result) {;
        return ApplicationConstants.SAVE;
    }
}

User.java

@Entity
@Table(name = "spring_user")
public class User implements Serializable {

    /** use serialVersionUID from JDK 1.0.2 for interoperatiblity */
    private static final long serialVersionUID = 1L;

    /** The userId is used to uniquely identify a user **/
    @Id
    @GeneratedValue
    @Column(name = "ID")
    private long userId;

    /** The name is used for name of the user */
    @Column(name = "NAME")
    private String name;

    /** The password is used for the password of the user */
    @Column(name = "PASSWORD")
    private String password;

    /** The age is used for age of the user */
    @Column(name = "AGE")
    private Integer age;

    /** The dob is used for date of birth of the user */
    @Column(name = "DOB")
    private Date dob;

    /** The loginName is used for loginName of the user */
    @Column(name = "LOGINNAME")
    private String loginName;

    /** The confirmPassword is used for reconfirm the password of the user */
    @Column(name = "CONFIRMPASSWORD")
    private String confirmPassword;

    /** The address is used for address of the user */
    @Column(name = "ADDRESS")
    private String address;

    /** The role is used for role (admin/guest) of the user */
    @Column(name = "ROLE")
    private String role;

When I build and run this sample application, then on accessing http://localhost:8080/SpringMVC-web/

it throws an error

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


Please help....

Please use the forum search as this question has been answered numerous times before...

Each request should go through the dispatcher servlet and the view should be selected by your controller and the model filled. You only have a POST method so this isn't happening. I suggest you take a look at the samples in the springsource repository on Github and read the reference guide on form handling.

Hi Marten,

Thanks for your response.

I searched about the same, but still could not find the answer, how can i make each request go thru the dispatcher servlet and view select by controller.
