[Twisted-Python] wxpython and xmlrpc via twisted

[Ian Jones]

I'm trying to create a taskbar app (in wxpython) to monitor job
progress on a render farm. I'd like the taskbar app to have an xmlrpc
server built in so that other applications can inform the taskbar app
additional jobs to monitor.

I found this recipe online which is a great example of the functionality I want:

http://code.activestate.com/recipes/298985/

However when I run the following

from xmlrpclib import *
s = ServerProxy('http://localhost:7080') # Get access to xmlrpc server
s.title('Hallo xmlrpc app')

I don't get a response (though the title in the window changes - so I
know it got it)

I do get this though:

I'm assuming this is just a good example that is out of date. However
I'm not sure how to update it so that it works. Can someone help me
out?
