This file helps you to configure your eclipse(possibly a home computer) to work with jDom. 

1. Download jDom 1.0 zip file from http://www.jdom.org/downloads/index.html. Get the binary code.
2. Extract the zip to your eclipse directory
3. In your eclipse IDE, after creating a new project, go to project->properties, choose Libraries tab, and choose to 
add External JARS. 
4. Locate the jDom.jar file from eclipse directory. 
5. Include the following lines at the beginning of your code:

import org.jdom.*;
import org.jdom.input.SAXBuilder;
import java.util.*;

It should work! I tried it with couple of examples. 

Btw, I need to clarify a bit on the assignment. This afternoon I told you guys that you need to handle both java class 
and python program as excutable. THIS WAS MY MISTAKE!!! The truth is, if you use java, you only need to handle java 
excutable; If you useu python, you only need to handle python excutable. Sorry for the confusion. 

Good Luck!
