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()

# client:

# NOTE: the client get nothing from sever-side and server-side get nothing from Axis2-client.

Apart from it, I made a server-side using soaplib. Still be failed though.

# server-side: soaplib

from soaplib.wsgi_soap import SimpleWSGISoapApp
from soaplib.service import soapmethod
from soaplib.serializers.clazz import ClassSerializer
from soaplib.serializers.primitive import String, Integer, Array, DateTime


class SMSService(SimpleWSGISoapApp):
    @soapmethod(_returns=Integer)
    def getPrice(self):
        return 11

if __name__=='__main__':
    try:
        from wsgiref.simple_server import make_server
        server = make_server('localhost', 7789,SMSService())
        server.serve_forever()
    except ImportError:
        print "Error: example server code requires Python >= 2.5"

#wsdl:  I cannot get wsdl form web browser, and I get the wsdl using "w3m http//localhost:7789/?wsdl' from the server-side.
