philjohn:
The Scalix managment interface IS SOAP! It's not REST. Scalix provides a REST interface for "regular" functions like retrieving/sending mail. But administration is done through SOAP. I'm sorry you think REST is simpler than SOAP also. That has not been my experience. If you're trying to do SOAP by hand, or the same way you do REST, I can see why you might think this. SOAP/WSDL by hand I think would be next to impossible, although folklore says in the early days coders actually did it!
have you ever tried consuming SOAP services built in one language with a client in another language?
Yup! I do .NET to java all the time.
f you would prefer integrating another way, go the way I am my Funambol connector
I'm not trying to send/receive mail, I'll just use IMAP connections for that. I need to administer users & groups.
