[SOLVED] class path resource [pointsconfig.properties] cannot be opened because it does not exist

Issue

I am trying to learn the basic of the Spring framwork. I am using the org.springframework.beans.factory.config.PropertyPlaceholderConfigurer in the sping.xml to print the properties of the PointA but I am getting the error below.

Triagle class

package org.stack;

import java.util.List;

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.BeanNameAware;
import org.springframework.beans.factory.DisposableBean;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class Triangle  {
    private Point PointA;
    private Point PointB;
    private Point PointC;
    private ApplicationContext context = null;

    public Point getPointA() {
        return PointA;
    }

    public void setPointA(Point pointA) {
        PointA = pointA;
    }

    public Point getPointB() {
        return PointB;
    }

    public void setPointB(Point pointB) {
        PointB = pointB;
    }

    public Point getPointC() {
        return PointC;
    }

    public void setPointC(Point pointC) {
        PointC = pointC;
    }

    public void draw() {

        System.out.println("Point A = (" + getPointA().getX() + ", "
                + getPointA().getY() + ")");
        System.out.println("Point B = (" + getPointB().getX() + ", "
                + getPointB().getY() + ")");
        System.out.println("Point C = (" + getPointC().getX() + ", "
                + getPointC().getY() + ")");

    }

}

DrawingApp

package org.stack;


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


public class DrawingApp {

    public static void main(String[] args) {


        AbstractApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
        context.registerShutdownHook();
        Triangle triangle =  (Triangle) context.getBean("triangle");
        triangle.draw();

    }
}

spring.xml

</bean>

<!-- We intialize here 3 Points objects -->
<bean id="pointA" class="org.stack.Point">
    <property name="x" value="${PointA.pointY}" />
    <property name="y" value="${PointA.pointY}" />
</bean>



<bean id="pointB" class="org.stack.Point">
    <property name="x" value="-20" />
    <property name="y" value="0" />
</bean>

<bean id="pointC" class="org.stack.Point">
    <property name="x" value="20" />
    <property name="y" value="0" />
</bean>


<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
  <property name="locations" value="pointsconfig.properties"></property>
</bean>

pointsconfig.properties file

PointA.pointX=0
PointA.pointY=0
