[XML-SIG] Re: Python Web Services and .NET - will it ever work

[Richard Kessler]

I am using just SOAP and have tried both literal and encoded with no
success. Initially I could not pass  parms. The .NET service complained of
null values. I discovered using the encoded ([SoapDocumentService
(Use=SoapBindingUse.Encoded)]   in the service allowed me to pass named
parameters. My soap message in looks like:
*** Outgoing SOAP ******************************************************
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"

<mycode xsi:type="xsd:string">S1234</mycode>
</GetCity>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

and .NET returns:

I haven't figured out what all this means at this point, but my confidence
level in the stability of Python talking to .NET is low (this may be my own
lack of knowledge too, but I am not sure this is a tried and true
technology).

Thanks for your response.
