JSF sample project managed beans error, unable to print managed beans message to html

I started to implement a very basic JSF application but i am unable to print the JSF Managed Beans message to html..

Here is my code :

HelloWorld.java :

package com.project.managedbeans;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;

@ManagedBean(name="helloWorld", eager=true)
@RequestScoped
public class HelloWorld {

private String message;

public HelloWorld(){
    System.out.println("Hello World Managed Bean is created");
}

public String getMessage(){
    return "Hello World ! ";
}

public void setMessage(String message){
    this.message = message;
}

index.html : 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">

<body>
#{helloWorld.message}

</body>
</html>

faces-config.xml

<?xml version="1.0" encoding="UTF-8"?>

<faces-config
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee     http://java.sun.com/xml/ns/javaee/web-facesconfig_2_1.xsd"
version="2.1">

</faces-config>

and web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-  app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

 <url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<context-param>

 <param-value>resources.application</param-value>
</context-param>
<listener>
 <listener-class>com.sun.faces.config.ConfigureListener</listener-class>
</listener>
</web-app>

and when i run the application on apache server, the page i see under

localhost:8080/jsfSampleProject/ is :

#{helloWorld.message}

I have JSF 2.1 Mojorra under Libraries tab. What do you think the problem is ?

Thanks.

The problem is that welcome file list accepts file names that are physically present in your web app, and that is index.xhtml. Note that none of your welcome files match that condition.

Next, your file is not handled by the FacesServlet. That is, requested URL does not correspond to the servlet URL mapping in your web.xml. Note that your mapping *.jsf doesn't match your requested files as well.

All in all, the following excerpt from web.xml will solve your problem:

<welcome-file-list>
    <welcome-file>index.xhtml</welcome-file>
</welcome-file-list>
<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>

Of course, you'll need the file index.xhtml at the root of your web application.
