http://nagoya.apache.org/bugzilla/show_bug.cgi?id=16846 Error in deserialization Summary: Error in deserialization Product: Axis Version: 1.0 Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Critical Priority: Other Component: Serialization/Deserialization AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I have come across what I believe to be a bug in the DeserializationContextImpl object. For background: I've got a thin soap client that is hitting an XML/A service on a machine to get some OLAP information. Right now I am just doing a basic query to get a list of data sources. The request goes over fine and tcpmon shows everything is returned fine (and I have validated the returned XML) but Axis keeps blowing up with: [java] org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize. It appears to blow up on the <TDP/><MDP/> tags. Don't know why though since the XML is valid. That is why I assume it is an Axis error. If someone could get back to me as soon as possible that would be great. I can't seem to find a way around this and I need it working in two days... Thanks! Here is the returned XML: <?xml version="1.0"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"; SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";> <SOAP-ENV:Body> <m:DiscoverResponse xmlns:m="urn:schemas-microsoft-com:xml-analysis"> <return SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
