If you mean, can I write a Jython class that implements a Java 
interface? then yes, this is commonly done. Just import the Java 
interface and list it as a base class to your class. For example:

from java.awt.event import MouseListener, MouseMotionListener
class TreeMouseListener(MouseListener, MouseMotionListener):

     def mousePressed(self, event):
         ...

You can preserve the environment yourself between uses. I think that if 
you create a PyDictionary and pass it to each interpreter instance they 
will all share the same namespace. Or maybe you can just reuse the same 
interpreter for each use of the script.
