Python soap using soaplib (server) and suds (client)

In the case of soap with python, there are recommendation to use soaplib (http://wiki.github.com/jkp/soaplib) as soap server and suds (https://fedorahosted.org/suds/) as soap client.
My target is to create soap services in python that can be consumed by several clients (java, etc).
I tried the HelloWorld example from soaplib (http://trac.optio.webfactional.com/wiki/HelloWorld).
It works well when the client is also using soaplib.
Then, I tried to use suds as client consuming the HelloWorld services and it fail.
-Why this is happening? Does soaplib server has problems to consumed by different clients?
Here the code for the server:
from soaplib.wsgi_soap import SimpleWSGISoapApp
from soaplib.service import soapmethod
from soaplib.serializers.primitive import String, Integer, Arraycode
class HelloWorldService(SimpleWSGISoapApp):
@soapmethod(String,Integer,_returns=Array(String))
def say_hello(self,name,times):
results = []
for i in range(0,times):
results.append('Hello, %s'%name)
return results
if __name__=='__main__':
from cherrypy.wsgiserver import CherryPyWSGIServer
#from cherrypy._cpwsgiserver import CherryPyWSGIServer
# this example uses CherryPy2.2, use cherrypy.wsgiserver.CherryPyWSGIServer for CherryPy 3.0
server = CherryPyWSGIServer(('localhost',7789),HelloWorldService())
server.start()
This is the soaplib client:
from soaplib.client import make_service_client
from SoapServerTest_1 import HelloWorldService
client = make_service_client('http://localhost:7789/',HelloWorldService())
print client.say_hello("Dave",5)
Results:
>>> ['Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave']
This is the suds client:
from suds.client import Client
url = 'http://localhost:7789/HelloWordService?wsdl'
client1 = Client(url)
client1.service.say_hello("Dave",5)
Results:
>>> Unhandled exception while debugging...
