WSDL for Service First Providers
How Integration Server generates the WSDL for a service first provider web service descriptor depends on the Pre-8.2 compatibility mode property.
*When the Pre-8.2 compatibility mode property is false, Integration Server includes or omits the <wsdl:output> element based on the service’s output signature. If the service:
*Has defined output, Integration Server includes a <wsdl:output> element, and the operation uses In-Out MEP.
*Has no defined output, Integration Server omits the <wsdl:output> element, and the operation uses In-Only MEP.
Note:Integration Server never includes a <wsdl:fault> element when generating WSDL for a service first provider. To have Integration Server use Robust In-Only MEP, after creating the web service descriptor, add a fault to the In-Only MEP operation to change the MEP to Robust In-Only MEP.
*When the Pre-8.2 compatibility mode property is true, Integration Server always includes a <wsdl:output> element for the operation, even when the service used for the web service descriptor has no output parameters. As a result, the operation uses In-Out MEP.
