Error while using annotation in Spring

Question

I am a newbie to advanced java and learning Spring framework. I found one tutorial

http://netbeans.org/kb/docs/web/quickstart-webapps-spring.html

In the code below

package contoller;

import java.net.BindException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.portlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import service.HelloService;
/**
*
* @author Manish
*/
public class HelloController extends SimpleFormController {

public HelloController() {
setCommandClass(Name.class);
setCommandName("name");
setSuccessView("helloView");
setFormView("nameView");
}
 private HelloService helloService;
 public void setHelloService(HelloService helloService) {
 this.helloService = helloService;
  }

@Override          // Error Method does not override or implment a method of supertype
protected ModelAndView onSubmit(
        HttpServletRequest request,
        HttpServletResponse response,
        Object command,
        BindException errors) throws Exception {

    Name name = (Name) command;
    ModelAndView mv = new ModelAndView(getSuccessView());
    mv.addObject("helloMessage", helloService.sayHello(name.getValue()));
    return mv;
  }

How can I fix this problem?

Regards.

@override is not spring annotation. It just indicates that method is an overriden method from super class. Your super class `SimpleFormController ` dont have a method with signature `protected ModelAndView onSubmit( HttpServletRequest request, HttpServletResponse response, Object command, BindException errors) throws Exception` — Subin Sebastian, Dec 22 '12 at 04:59
If i remove this, will it be ok to use. I think it will throw an error. If there is no method in this class then we should not override it. — Manish, Dec 22 '12 at 05:02

Error: Method does not override or implment a method of supertype

This is not related to Spring. It says in your SimpleFormController class there is no method onSubmit.

Add this method to your SimpleFormController class and the problem is solved.

There is a onSubmit Method available in SimpleFormController class. – Kapil Aug 26 '13 at 12:27
