[Jython-users] Demo of COM and Jython working together

[<Dan...@at...>]

Hi all.
Last week or so, I asked about strategies for using 
jython to access COM objects. Various (good) responses 
came back, and I put them to use. 
The best suggestion was to use XML-RPC to allow a jython 
instance (which doesn't support COM) to communicate with 
a CPython instance (which does support COM).
Here's a cutesy demo that runs a Microsoft Agent (one of 
their little anthropomorphs like the MSOffice paper 
clips) from a JavaAwt controller. The in-machine 
protocol is XML-RPC. (Apologies for any damage to the 
source done by my mailer program.) Windows 2000 should 
have at least one agent character (Merlin.acs) installed 
in <root-drive>:\WINNT\MSAGENT\CHARS

1). here's the Server side which should be run from 
CPython:
_________________ CUT HERE__________________________
# Run this under Python21 with the XMLRPC lib stuff 
inserted into PythonPath
# must have installed ActiveState Python (ActivePython-
2.1.1.msi)and win32all.exe
from win32com.client import *
import SimpleXMLRPCServer
import os,sys,time,string



class Anthropomorph:

	def __init__ (self, agent="Merlin"):
		self.agentName=agent

	def initAgent(self):
		self.dispatchID = Dispatch
("Agent.Control.2")      # load the control
	
	self.dispatchID.Connected=1                      
  # Connect!
		fullName = self.agentName+'.acs'
		print "initAgent",fullName
		self.dispatchID.Characters.Load
(self.agentName, fullName)
		self.anAgent = self.dispatchID.Characters
(self.agentName)
		#print "initAgent", self.anAgent
		return "Anthropomorph: initAgent done."

	def startAgent (self):
		print "startAgent",self.anAgent
		self.anAgent.Show()
		self.anAgent.Play("Greet")
		self.anAgent.MoveTo(820,600,1000)
		time.sleep(5) # padding so that the 
anthropomorph can perform
		return "Anthropomorph: startAgent done."

	def play(self, gesture, delay=5):
		print "play",self.anAgent
		self.anAgent.Play(gesture)
		time.sleep(delay) # padding so that the 
anthropomorph can perform
		return delay
	def say (self, phrase, delay=5):
		print "say",self.anAgent
		self.anAgent.Speak(phrase)
		time.sleep(delay) # padding so that the 
anthropomorph can perform
		return delay
	def hide(self, delay=0):
		time.sleep(delay) # padding so that the 
anthropomorph can perform
		self.anAgent.Hide()
		return delay

		
server = SimpleXMLRPCServer.SimpleXMLRPCServer
(("localhost", 8000))
server.register_instance(Anthropomorph())
print 'SimpleXMLRPCServer @ localhost:8000'
server.serve_forever()

_____________________ END SERVER CODE______________

2). Client Code, simply creates an awt fixture and 
communicates with the Server. run this with jython
__________________ CUT HERE_________________________
# Client code

import xmlrpclib
from java import awt



class Marionette:
	def __init__(self):
		self.agent = xmlrpclib.Server
('http://localhost:8000')
		print self.agent.initAgent()
		print self.agent.startAgent()

	def saySomething(self,anExpression):
		self.agent.say(anExpression)
	def doSomething(self,anAction):
		self.agent.play(anAction)
	def hideMe(self):
		self.agent.hide()



if __name__ == '__main__':
	def animate(e):
		#print 'animate called'
		animation.caretPosition=0
		#animation.selectAll()
		puppet.doSomething(animation.getText())
	
	def speak(e):
		#print 'speak called'
		speech.caretPosition=0
		#speech.selectAll()
		puppet.saySomething(speech.getText())
		
	puppet = Marionette()
	panel0= awt.Panel(layout=awt.BorderLayout())
	panel1= awt.Panel(layout=awt.GridLayout())
	
	label0 = awt.Label('Animation:')
	animation = awt.TextField(text='Greet', 
actionPerformed=animate)
	
	label1 = awt.Label("Say This:")
	speech = awt.TextField(text='Hello Folks', 
actionPerformed=speak)
	
	panel1.add(label0)
	panel1.add(animation)
	panel1.add(label1)
	panel1.add(speech)
	
	panel0.add(panel1, 'Center')
	
	
	import pawt	
	pawt.test(panel0, size=(300,56))
	
	animate(None)
