5.10. ServiceInvoker

The ServiceInvoker (org.jboss.soa.esb.client.ServiceInvoker) manages the delivery of messages to the specified Services. It also manages the loading of end-point references and the selection of couriers, thereby providing a unified interface for message delivery.
The ServiceInvoker was introduced to help simplify the development effort as it hides much in the way of the lower-level details and works opaquely with the stateless service fail- over mechanisms. As such, ServiceInvoker is the recommended client-side interface for using services within the JBoss Enterprise SOA Platform.
You can create an instance of the ServiceInvoker for each service with which the client interacts. Once created, an instance examines the registry to determine the primary end-point reference and, in the case of fail-overs, any alternative end-point references.
