WSDL for WSDL First Providers and Consumers
For WSDL first provider or consumer web service descriptors, Integration Server uses the original WSDL as is.
For a WSDL first provider web service descriptor, when the Pre-8.2 compatibility mode property is false, Integration Server uses a MEP type based on the WSDL. When Pre-8.2 compatibility mode property is true, Integration Server uses In-Out MEP regardless of whether the WSDL for an operation includes a <wsdl:output> element.
For a consumer web service descriptor, the Pre-8.2 compatibility mode property does dictate how a web service connector reacts to receiving unexpected SOAP responses. When the Pre-8.2 compatibility mode property is set to true, Integration Server is more tolerant of unexpected SOAP responses. For more information, see How <wsdl:output> and <wsdl:fault> Elements Affect a Consumer.
Note:
For consumer web service descriptors, Integration Server provides partial support for Robust In-Only for SOAP over JMS. For more information, see Consumer Support for Robust In-Only Operations with SOAP/JMS Bindings.
