This is my project structure:-

package com.home.pack;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.ui.ModelMap;

@Controller
@RequestMapping("/hello")
public class HelloController{

   @RequestMapping(method = RequestMethod.GET)
   public String printHello(ModelMap model) {
      model.addAttribute("message", "Hello Spring MVC Framework!");

      return "hello";
   }

}

web.xml

<web-app id="WebApp_ID" version="2.4"
   xmlns="http://java.sun.com/xml/ns/j2ee"

</beans>

hello.jsp

<%@ page contentType="text/html; charset=UTF-8" %>
<html>
<head>
<title>Hello World</title>
</head>
<body>
   <h2>${message}</h2>
</body>
</html>

I am following this tutorial -> http://www.tutorialspoint.com/spring/spring_mvc_hello_world_example.htm but I am not able to get it to work. It seems that I am missing something here and would really appreciate if anybody points that out. Thanks.

You are trying to show the page "hello"? Spring probably see it as the controller since you did @RequestMapping("/hello") ... So I guess here you're trying to show the controller as a page, that will surely show 404 error.

Try to change your method as fallow:

@RequestMapping(value = "/hello", method = RequestMethod.GET)
public String printHello(ModelMap model) {
   model.addAttribute("message", "Hello Spring MVC Framework!");

   return "hello";
}

And remove the request mapping on the controller I guess it would work better...

Or let the request mapping on your controller and change your request mapping of the method for something else and acces it by adding .../hello/yourMethodValue
