I just read the article “Simple and Efficient Jython Object Factories” submitted by Charlie Groves in Oct 2006 and want to play the demo code.

Would anyone let me know how to

import org.python.core.PyObject;
import org.python.core.PyString;
import org.python.util.PythonInterpreter;


and where I should put the Employee.py file


I use Eclipse to create the demo project.
