NullPointer Exception while loading bean file through ClassPathXmlApplicationContext

[avinash.madireddy]

Hi,

I'm a beginner to spring. I'm getting a nullpointer exception while loading the bean class.

I loaded all the required spring jars.

Can any help me to solve this problem.


Project structure:

HellpSpring
-src
--com.tutorialspoint
---HelloWorld.java
---MainApp.java
--Beans-config.xml

Thank you!



Main file
-----------

package com.tutorialspoint;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlAp plicationContext;

public class MainApp {

public static void main(String[] args) {

ApplicationContext context = new ClassPathXmlApplicationContext("Beans-config.xml");

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

obj.getMessage();

}

}
-----
HelloWorld

package com.tutorialspoint;

public class HelloWorld
{
private String message;
public void setMessage(String message)
{
this.message = message;
}
public void getMessage()
{
System.out.println("Your Message : " + message);
}
}

Beans-config.xml

<bean id="helloWorld" class="com.tutorialspoint.HelloWorld">

<property name="message" value="Hello World!"/>

</bean>
