пружинный контроллер не смог распознать

Я попробовал следующий код для запуска примера приложения Spring Rest с tomcat7. Он работает правильно, но не может распознать HelloController. Отладчику не удалось получить доступ к hellocontroller. http://localhost:8080/Sample/welcome выдает ошибку 404.

127.0.0.1 - - - 25/09/2015:23:21:27 +0530 "GET / HTTP/1.1" 404 -
127.0.0.1 - - - 25/09/2015:23:21:28 +0530 "GET /Sample/ HTTP/1.1" 200 -
127.0.0.1 - - - 25/09/2015:23:21:34 +0530 "GET /Sample/welcome HTTP/1.1" 404 -

HelloController.java

package com.mkyong.web.controller;


   @Controller
public class HelloController {

    @RequestMapping(value = { "/", "/welcome**" }, method = RequestMethod.GET)
    public ModelAndView welcomePage() {

        ModelAndView model = new ModelAndView();
        model.addObject("title", "Spring Security Hello World");
        model.addObject("message", "This is welcome page!");
        model.setViewName("hello");
        return model;

    }

    @RequestMapping(value = "/admin**", method = RequestMethod.GET)
    public ModelAndView adminPage() {

        ModelAndView model = new ModelAndView();
        model.addObject("title", "Spring Security Hello World");
        model.addObject("message", "This is protected page!");
        model.setViewName("admin");

        return model;

    }

}
