"cannot be cast" in Spring

I tried to run a simple Spring (4.0.0 release) program using Eclipse. But I'm stuck in one place. It says "cannot be cast".

Drawing.java

package org.spring; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Drawing { public static void main(String[] args) { ApplicationContext context= new ClassPathXmlApplicationContext("org/spring/spring.xml"); Square myBean= (Square) context.getBean("square"); myBean.paint(); } 

Square.java

package org.spring; public class Square { public void paint() { System.out.println("Square Drawn"); } } 

spring.xml

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd"> <beans> <bean id="square" class="org.spring.Drawing"> </bean> </beans> 

When I tried to execute it it prints:

Exception in thread "main" java.lang.ClassCastException: org.spring.Drawing cannot be cast to org.spring.Square at org.spring.Drawing.main(Drawing.java:10)
