An embedded interpreter sounds ideal for your situation, if I've
understood everything correctly. You could execute a .py file in the
embedded interpreter, then retrieve the class defined in that file as a
Java object with the interpreter's get method.  A good example of this is
the org.python.util.PyServlet class that comes with Jython.
