Spring - Loading XML bean definitions from class path resource [Beans.xml]- NoClassDefFoundError

Question

I'm a newbie for Spring and I was referring to this tutorial for my first Spring project. After follow all the instruction, I try to run the program but I'm having this error.

May 26, 2015 11:42:45 AM org.springframework.context.support.ClassPathXmlApplicationContext prepareRefresh
INFO: Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@31221be2: startup date [Tue May 26 11:42:45 CST 2015]; root of context hierarchy

Any idea where I did the wrong. As I know I was following the tutorial correctly.

CODE

package com.tutorialspoint;

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

public class MainApp {
   public static void main(String[] args) {
      ApplicationContext context = 
             new ClassPathXmlApplicationContext("Beans.xml");

      HelloWorld obj = (HelloWorld) context.getBean("helloWorld");

      obj.getMessage();
   }
}

Beans.XML

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

<beans xmlns="http://www.springframework.org/schema/beans"
    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">

   <bean id="helloWorld" class="com.tutorialspoint.HelloWorld">
       <property name="message" value="Hello World!"/>
   </bean>

</beans>

Check if you have added all the required jars in your classpath.

The class org.springframework.expression.ParserContext lies inside spring-expresssion-YOUR_SPRING_VERSION.jar Check if you have this jar added on classpath.
