Choose which service is used at run time, using WebSphere® Service Registry and Repository (WSRR) to lookup service endpoints.
If your goal is to have service requests routed to endpoints that are selected dynamically, you can achieve this by using a WSRR registry combined with an Endpoint Lookup mediation primitive. The run time supports dynamic endpoint selection, but you must set the Use dynamic endpoint property in your mediation module.
If you decide to use service-version-aware routing, service requests are dynamically routed to a specific version of a module.
