The environmental variable for sys.path is JYTHONPATH in Jython to
avoid stepping on CPython's toes.  You can also set the python.path
property when initializing your PythonInterpreter.

Also, if you're following the examples, the Employee class is in a
file named employee.py.  That means if the directory containing
employee.py is on your JYTHONPATH, you'll need use "from employee
import Employee" to get to the class.  It's contained in the employee
module, not exposed directly like a Java class.  If that still doesn't
work, try importing sys and printing out sys.path in your Python code
before importing employee.  That will let you see where Python is
importing from and if it's missing your modules.
