Webapp does not find controller

Question

I've been trying to figure out something which has been vexing me for a the whole day. I'm trying to run a very simple SpringMVC but the webapp doesn't seem to pick up any of the controllers i've set up. Any help would be great

Web.xml

<web-app version="2.4"

  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  </context-param>

</web-app>

    </bean> 

</beans>

HelloWorldController.java

package com.thehit.controllers;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping("/welcome")
public class HelloWorldController {

    @RequestMapping(value="/hello", method = RequestMethod.GET) 
    public String printWelcome(ModelMap model) {
        model.addAttribute("message", "Spring 3 MVC Hello World. This is HelloControllerClass.");
        return "hello"; 
    } 
}

The jsp file is located in WEB-INF/pages

When I navigate to the following addresses "http://localhost:8080/TheHitWebProject/welcome" or "http://localhost:8080/TheHitWebProject/hello" I get the following error:

HTTP Status 404 -

type Status report

message

description The requested resource is not available.

Apache Tomcat/7.0.53

I know i am missing something basic here but i've been at it for hours and can't figure it out. Any help will be really appreciated

Thanks

You're missing mvc:annotation-driven:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

    <mvc:annotation-driven/>

</beans>

Also remember that @RequestMapping from @Controller is added before @RequestMapping from method so url will be:

http://localhost:8080/TheHitWebProject/welcome/hello
