Cool! That is simpler than I thought it would be, but I still can't
figureout how to pass something into a Lua implemented Interface like your
first example that contained the following code.
		LuaState l = LuaStateFactory.newLuaState();
		l.doFile("LuaLogic.lua");
		LuaObject logic = l.getLuaObject(-1);
		IBusinessLogic jlogic = (IBusinessLogic)
logic.createProxy("IBusinessLogic");
		jlogic.doLogic();
		l.pop(1);

if the interface signatgure was
     TestDataObject IBusinessLogic.doLogic( TestDataObject );

what would I have to do to the above code to pass the TestDataObject in
and get one back?

Thanks for all the help.
