> Anybody experienced with SOAP (http://www.w3.org/TR/SOAP/)? Guess what... Narval uses it for its UI/engine communication :-) We use www.pythonware.com's implementation. SOAP is slow... because parsing XML messages is slow and using a generic format for marshalling objects is verbose (ie much slower than Corba and its stub mechanism). But it works and looks like a good open-standard candidate. -- Nicolas Chauvat http://www.logilab.com - "Mais où est donc Ornicar ?" - LOGILAB, Paris (France)
