Spring Maven DispatcherServlet noHandlerFound

I am new to java world. I am following one tutorial to learn java. The tutorial using Spring framework and maven build. but when I reached the part to use DispatcherServlet, mine doesn't work as it suppose. It shows this on console: 

org.springframework.web.servlet.PageNotFound noHandlerFound

WARNING: No mapping found for HTTP request with URI [/index.html] in DispatcherServlet with name 'dispatcher'

and browser can't load just simple hello world string. browser says

HTTP ERROR 404
Problem accessing /index.xml. Reason:
Not Found
Powered by Jetty://

This seems common problem becasue there are a lot of discussions about this. I have read several of them and tried some answers but nothing helps. Can anyone check my code and point out what might cause this problem?

web.xml

@Controller
public class IndexController {

  @RequestMapping("/index")
  public String index(){
    return "WEB-INF/jsp/index.jsp";
  }
}

index.jsp

hello from spring web mvc
</body>
</html>

Additional comment (solution): it was right reference, I made some mistakes and then it didn't work afterwards even with the right code. when this kind of situation (after mistakes and back to right code - still not working), then need to perform 'Project - clean' before run. (maybe the basics.) So that solved. Thanks.

It should be @RequestMapping annotation.

@RequestMapping(value="/index")
  public String index(){
    return "WEB-INF/jsp/index.jsp";
  }
