To configure a web service application to use WS-ReliableMessaging, you attach a policy set that contains a WS-ReliableMessaging policy type. This policy type offers a range of qualities of service: managed persistent, managed non-persistent, or unmanaged non-persistent.
Develop a Java API for XML-Based Web Services (JAX-WS) provider or requester application, and configure a policy set to enable WS-ReliableMessaging. Install your application then attach the policy set. If you want to use either of the managed qualities of service, bind the application or policy set to a service integration bus and messaging engine.
