My simple "Hello World" program is not running into Spring? :(

I'm trying to run my simple program, i added spring framework jar files and common-logging jar files too into my reference library.

Here is my first program says HelloWorld.java :

package com.rajendra.lesson01;

public class HelloWorld {

    private String message;

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

    public void getMessage(){
        System.out.println("Messge: "+message);
    }
}

Here is my another program says MainProgram.java :

package com.rajendra.lesson01;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MainProgram {
    public static void main(String[] args){

        ApplicationContext ac=new ClassPathXmlApplicationContext("bean.xml");
        HelloWorld hw=(HelloWorld) ac.getBean("helloWorld");

        hw.getMessage();
    }
}

and here is my last one bean.xml :

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://ift.tt/GArMu6"
    xmlns:xsi="http://ift.tt/ra1lAU"
    xsi:schemaLocation="http://ift.tt/GArMu6 http://ift.tt/1jdM0fG">

<bean id="helloWorld" class="com.rajendra.lesson01.HelloWorld">
    <property name="message" value="My name is foo.." />
</bean>

</beans>

Everything goes fine according to tutorial but my Output says:
