Hi Burak,

Thanks much for your replay.

part 1:

What you want to said is below, is not it?

1: soaplib work as client is incomplete. A good choice for webservice client is suds.

2: "Currently, the only advantage of using rpclib as a soap client is its speed and if you need speed that bad, you should not be using soap (or xml) anyway.",

do you mean that soap is slow and we did nothing about it.

part 2:

"Does this answer your question, or is there any more", In fact, i want to know why sometimes suds throws a stack of exceptions when invoke soaplib sever. I have to admire most of time it's okay and wastes longer time.

The details is reported in problem 2 of my mail.

part 3: Do you have some experience about Java Axis2?

I developed a webservice server-side using tornadows(tornadow webservice.Besides soaplib, tornadows is the best server-side I have meet). I use suds-client invoke tornadows-server successfully. While, if i use Java Axis2 invoke it, nothing happened and the request nearly not reach the server.

In actual fact, how to invoke a webservice server-side successfully is my true question. What I need is provide a python webservice server-side which can be invoked by Java Axis2. This is why i try to find a good webservice server-side, including soaplib.

you can see the code in detail:

# 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()

Does this answer your question, or is there any more questions hidden in the heap below?

Hi, all:

Recently, I have been do something about python webservice. Above all the methods of python webservice, soaplib is welcome and popular. When using soaplib, some problems puzzled me as follows.

porlbem 1: soaplib provide client-side or not？

Usually, I use soaplib as follows:

# file-name: soaplib_server.py:

# -*- coding:utf-8 -*-

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 SMS(ClassSerializer):

class types:

mobile = String

content = String

class SMSService(SimpleWSGISoapApp):

@soapmethod(String, _returns=Array(SMS))

def get_sms(self,id):

sms_lst = []

sms = SMS()

sms.mobile = "13011292217"

sms.content = "hi, it's a test!"

sms_lst.append(sms)

return sms_lst

def make_client():

from soaplib.client import make_service_client

client = make_service_client('http://localhost:7789/' ,SMSService())

return client

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"

#file-name: suds_client.py

import suds

def test_soaplib3():

import logging

logging.basicConfig(level=logging.ERROR)

url = "http://localhost:7789/?wsdl"

client = suds.client.Client(url,cache=None)

print 'client', client

output = client.service.get_sms('jia')

print 'output', output

#NOTE: Certainly, it's okay. Below is the output:

#output:

client

Suds ( https://fedorahosted.org/suds/ ) version: 0.3.7 GA build: R580-20091016

ns0 = "SMSService.SMSService"

Ports (1):

Methods (1):

Types (4):

output (SMSArray){

_type = "tns:SMSArray"

SMS[] =

(SMS){

content = "hi, it's a test!"

mobile = "13011292217"

},

}

#NOTE: do you find the "def make_client():" in the server-side ? It's no use when we use suds_client.py. Now, let me talk the problem:

I think soaplib is only a server-side and without client, you also can find the words as follows in "http://soaplib.github.com/soaplib/2_0/":

"Soaplib is an easy to use Python library for publishing SOAP web services using WSDL 1.1 standard, and answering SOAP 1.1 requests. With a very small amount of code, soaplib allows you to write a useful web service and deploy it as a WSGI application. (Non-WSGI scenarios are also supported.)"

Most of scenes, soaplib make as server and suds did for client. They can work together well.

In a web page, I found someone use client by soaplib, the client can be write as follows:

# file-name: soaplib_client.py

# -*- coding:utf-8 -*-

from soaplib_server3 import SMSService

from soaplib_server3 import make_client

import lxml.etree as et

a = make_client()

ret = a.get_sms('jia')

print 'ret:', ret

print 'type of ret:', type(ret)

for i,r in enumerate(ret):

print 'i:',i, r.mobile, r.content

#output:

ret: [<soaplib_server3.SMS object at 0x8ecf7ec>]

type of ret: <type 'list'>

i: 0 13011292217 hi, it's a test!

#NOTE: now, the questions are :

1: Whether soaplib can provide client?

2: If the answer for question 1 is okay, then the second question is : how to provide a webservice client using soaplib? Is the method "client = make_service_client('http://localhost:7789/' ,SMSService())" which is be used in my soaplib_serve.py?

3: if you agree that soaplib can make as websevice client-side, I would like to ask:　The client relays so heavily on sever-side, in the client-side, it requests some classes or modules in server side are imported. If we use soaplib-client to invoke a remote server(it may be developed in Java, C#, php or other language, or python which is not in the some local), how we get the class in server?

I do not whether i speak my question clearly. In actual fact, what I eager to know is how to provide a client-side using soaplib if soaplib can.

part 2: Is there someone find it spend much time and not stable to invoke soaplib using suds as follows.

#NOTE: the code can also be found in "http://soaplib.github.com/soaplib/2_0/pages/helloworld.html"

# soaplib_server.py

import soaplib

from soaplib.core.service import soap

return results

if __name__=='__main__':

soap_application = Application([HelloWorldService], 'tns')

wsgi_application = wsgi.Application(soap_application)

output = client.service.say_hello('jia',3)

when you invoke sus.py , it takes much time and a long time later returns the right result
