Asynchronous Services publish asynchronous BPEL process style WSDL that contains two portTypes. One portType defines the interface for the incoming request to the asynchronous service and another portType defines the interface for the callback service. Use this annotation to customize the names of the different components of callback portType and related entities.
The service reference name used for the service reference that is used to send the response message. The default value is [class name with this annotation] + SERVICE_REF_NAME_SUFFIX This value must be unique for the deployable archive. This value is used for the <service-ref-name> and <display-name> elements under the <service-ref> element in the standard deployment descriptor for the deployable archive. This value is used for the name attribute in the <service-ref-mapping> element in the proprietary deployment descriptor for the deployable archive.
