how to make a axis2-client for a python webservice server-side - suds - Fedora mailing-lists

6 Dec 2011


      Hi, all:
I was doing something about webservice.
What a need to do is using a axis2-client to invoke a webservice developed by
python. I tried to provide kinds of webservice server-side, and invoke them
by axis2-client. While, all is failed.
In the contents below, I provide the wsdl, axis2 client-side and the
server-side made by python.
Hope some axis2 experts can give me some points. Thanks ahead.
Method 1:
# server-side:  tornadows
import logging
import tornado.httpserver
import tornado.ioloop
import tornado.web
from tornadows import soaphandler
from tornadows import webservices
from tornadows import xmltypes
from tornadows.soaphandler import webservice
from tornado.options import define, options
define('mode', default='deploy')
define('port', type=int, default=8000)
options['logging'].set('warning')
class SMSService(soaphandler.SoapHandler):
@webservice(_params=xmltypes.Integer,_returns=xmltypes.Integer)
    def getPrice(self,a):
        return 1987
if __name__ == '__main__':
    service = [('SMSService',SMSService)]
    app = webservices.WebService(service)
    ws  = tornado.httpserver.HTTPServer(app)
ws.listen(options.port)
    logging.warn("SMSService running on: localhost:%d", options.port)
    tornado.ioloop.IOLoop.instance().start()
