I know this is well worked territory, but I'm getting this error: suds.TypeNotFound: Type not found: '(schema, http://www.w3.org/2001/XMLSchema, )' Even though the expectation (I think) with suds 0.4 that we shouldn't be seeing this anymore. I've also used the workaround as documented here: https://fedorahosted.org/suds/wiki/TipsAndTricks#Schema-TypeNotFound The source code is: from suds.client import Client from suds.xsd.sxbasic import Import url = 'http://www.davidjanes.com/wsdl/sample.wsdl' Import.bind('http://schemas.xmlsoap.org/soap/encoding/') client = Client(url, cache = None) And the very short sample WSDL is available at the URL in the code. Any thoughts? David
