Exception when using ClassPathXmlApplicationContext function

Question

I was using the ClassPathXmlApplicationContext to read my xml. But on execution I am getting the error as stated under . I have also checked the file names and I have also executed the same program using XmlBeanFactory function which returns the desired output

Here is my code

  package org.lalit.springsession;

  import org.springframework.beans.BeansException;
  import org.springframework.beans.factory.BeanFactory;
  import org.springframework.beans.factory.NoSuchBeanDefinitionException;
  import org.springframework.beans.factory.xml.XmlBeanFactory;
  import org.springframework.context.support.ClassPathXmlApplicationContext;
  import org.springframework.core.io.FileSystemResource;

  public class DrawingApp {

public static void main(String[] args) {
    // TODO Auto-generated method stub



         /*
    BeanFactory factory = new XmlBeanFactory(new        FileSystemResource("spring.xml")) ;
    Triangle triangle=  (Triangle) factory.getBean("triangle");
    triangle.draw();
    */

    BeanFactory factoryObj = new ClassPathXmlApplicationContext("spring.xml");
    Triangle triangle=  (Triangle) factoryObj.getBean("triangle");
    triangle.draw();
}

}

These are Exceptions which I am facing.

Answer 1

Your spring.xml isn't on your classpath, it resides somewhere on your file system. Your XmlBeanFactory is loading the file from the file system the ClassPathXmlApplicationContext defaults to the classpath.

Either move the file to your classpath or modify the constructing of ClassPathXmlApplicationContext and prefix with file:.

    BeanFactory factoryObj = new ClassPathXmlApplicationContext("file:spring.xml");

Answer 2

Your configuration is correct.The problem here is the spring file is not loaded by the Drawing class So add your spring.xml file to the classpath by moving spring.xml to the src folder of your project..
