19.13. Indirect Service Invocation

SwitchYard services can be indirectly invoked through the SwitchYard Exchange mechanism. This reduces the coupling between JSF components and SwitchYard Service implementations. This is done by invoking a SwitchYard CDI Bean Service and the SwitchYard Exchange mechanism through a @Reference injected Service reference. This provides a client side proxy bean that handles all the SwitchYard Exchange invocation details for all the operations exposed by the service.
The proxy beans for these invocations are not available (through CDI) to the JSF components. To work around this, users can create a standard named (@Named) CDI bean. It must contain a @Reference between the JSF components and the SwitchYard CDI Bean services.
