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

I'm new to Spring, and I was referring to this tutorial for my first Spring project. After completing the entire instruction, I try to run the program, but I have this error.

Any idea where I did wrong. As far as I know, I followed the textbook correctly.

THE 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 necessary banks to your class path.

The class org.springframework.expression.ParserContextis inside. spring-expresssion-YOUR_SPRING_VERSION.jarCheck if this bank is added to the class path.

I had the same problem. But I found my mistake.

: "Beans.xml" com.tutorialspont.

"Beans.xml" src.

Solution to the above problem: This happens if spring -expression-xxx.Release.jar is inaccessible in your class path. Add the spring -expression-3.2.3.RELEASE or latest fix to your class path to fix this problem.

Actually, your class name is MainApp and in the .xml file that you mentioned as this class = "com.tutorialspoint.HelloWorld". But it should be like class = "com.tutorialspoint.MainApp". Please follow this action and then run, I think it will work correctly.
