[Twisted-web] Can't get XMLRPC server working with Twisted 2.1

Mon Nov 14 08:35:46 MST 2005

Hello Twisters,

I've looked in the documentation, searched the archives and the web, but
found no solution to the XMLRPC problem I'm having.

I've used the finger example code to create an XMLRPC server, but I keep
getting the 405 Method not allowed error. I'm probably overlooking
something very obvious, call me stupid, but I can't get it to work.
Below the code I'm using.

If someone has a clue ... please enlighten me.

And the client code:

from twisted.web.xmlrpc import Proxy
from twisted.internet import reactor

def printValue(value):
    print repr(value)
    reactor.stop()

def printError(error):
    print 'error', error
    reactor.stop()

proxy = Proxy('http://localhost:7080')
proxy.callRemote('echo', 'hello world').addCallbacks(printValue, printError)
reactor.run()
