wsdl (soap) without code generation

[Thomas Guettler]

Hi,

I looked for a solution to talk to a web service which
offers its signature with a wsdl file.

I googled for 'wsdl python' and found ZSI.

This project uses code generation. That's something
I don't like.

The book 'dive into python' uses SOAPpy. This looks
better since it does not generate source code.
But the last release and first release is from 2001.

ZSI seems to have integrated SOAPpy.

I am new to WSDL and SOAP. Do I need a WSDL parsing
routine at all? I guess my wsdl definition won't change
during the next years. So I could read the wsdl with
my eyes and make a fitting soap call...

Any thoughts?

I've been using SOAPpy directly in one of my projects, and so far my
experience couldn't be better.
SOAPpy can handle (hand-written) WSDLs well enough for me, and so far
it has given me no problems at all.

This is current solution, but it is quite new and actively developed, so newer
versions are sometimes not compatibile with old ones. So if you use distribution
provided packages (eg Debian) you can have troubles after system upgrade and
regenerating stub.

This project uses code generation. That's something
I don't like.

But after you have generated files it is easy to use that tool -- just call a
function and grab result.

With ZSI you don't have to generate code, but you will have to do more coding to
invoke a call.

No -- you don't have to read WSDL at all! Just make somebody else do it for you.
SOAP is just about sending and receiving text, but you have to keep that
properely formated. You don't have to use automation of WSDL and XML parsing.

For example visit:

http://soapclient.com/soaptest.html

put your wsdl file address, click Retrieve. Then fill forms and see what is
response and reply -- they will be your templates. Then write simple Python
programs with socks sending and receiving templates on http (or https) port. If
you gave me your wsdl file address I could probably give more precise help.

Here goes example: http://www.ibm.com/developerworks/li...s-pyth5/#code3

....

Thank you for your answers. I tried to parse the wsdl with two
libraries. (axis2 (java) and SOAPPy). Both fail because there
is no entry for 'service'.

The wsdl is from SAP XI.

Has someone hints?
