如何解決SPRING中由FileNotFoundException引起的BeanDefinitionStoreException？

我正在嘗試使用SPRING調用三角形bean中的方法draw（）的活動。但是，當我嘗試訪問spring.xml文件時遇到了一個錯誤。如何解決SPRING中由FileNotFoundException引起的BeanDefinitionStoreException？

的錯誤是：

Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [spring.xml]; nested exception is java.io.FileNotFoundException: class path resource [spring.xml] cannot be opened because it does not exist

這裏是主這是SpringApplication.java：

package org.spring.application; 

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

public class SpringApplication 
{ 

    public static void main(String[] args) 
    { 
     AbstractApplicationContext context = new ClassPathXmlApplicationContext("spring.xml"); 
     Triangle triangle = (Triangle) context.getBean("Triangle"); 
     triangle.draw(); 
    } 

}

這裏是在spring.xml代碼

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

<beans> 
     <bean id="Triangle" class="org.spring.application.Triangle"/> 
</beans>

這裏是項目文件夾： Project Folder

我正在使用NetBeans IDE。我還包括Spring庫和組件日誌記錄。有人可以幫助我，並指出如果我做錯了什麼。謝謝。
