Python – Generating a WSDL using Python and SOAPpy


First of all, I will admit I am a novice to web services, although I'm familiar with HTML and basic web stuff. I created a quick-and-dirty web service using Python that calls a stored procedure in a MySQL database, that simply returns a BIGINT value. I want to return this value in the web service, and I want to generate a WSDL that I can give our web developers. I might add that the stored procedure only returns one value.

Here's some example code:


import SOAPpy
import MySQLdb

def getNEXTVAL():
    cursor = db.cursor()
    cursor.execute( "CALL my_stored_procedure()" )  # Returns a number

    for record in result:
        return record[0]

db=MySQLdb.connect(host="localhost", user="myuser", passwd="********", db="testing")
server = SOAPpy.SOAPServer(("", 8080))

I want to generate a WSDL that I can give to the web folks, and I'm wondering if it's possible to have SOAPpy just generate one for me. Is this possible?

When I tried to write Python web service last year, I ended up using ZSI-2.0 (which is something like heir of SOAPpy) and a paper available on its web.

Basically I wrote my WSDL file by hand and then used ZSI stuff to generate stubs for my client and server code. I wouldn't describe the experience as pleasant, but the application did work.
