Turbogears web service connection with SUDS -- connection denied

Hi everyone, I'm trying to make a simple web service, described
here.
I am using turbogears1 installed from the ubuntu repos:


#controller.py

from turbogears import controllers, expose, flash

from tgwebservices.controllers import WebServicesRoot, wsexpose, wsvalidate


class EchoService(WebServicesRoot):

    """EchoService web service definition"""


    @wsexpose(str)

    @wsvalidate(value=str)

    def echo(self, value):

        "Echo the input back to the caller."

        return value


class Root(controllers.RootController):

    """The root controller of the application."""


    echo = EchoService('http://localhost:7000/echo/')

I can view the WSDL file in my browser, but I want to be able to access it
from a python script, so I downloaded the SUDS module... but this didn't
work:


>>> from suds.client import Client

>>> url = 'http://0.0.0.0:8080/echo/soap/api.wsdl'

>>> client = Client(url)

>>> print client


Suds ( https://fedorahosted.org/suds/ )  version: 0.3.9 GA  build:

>>> resut = client.service.echo("hi")

Is this is problem with the web service or the client?
