3.7. Component Reference

A component reference allows a component to consume other services. A component reference can be wired to a service offered by another component in the same application or it can be wired to services outside the application with a composite reference. Similar to component services, all component references have a contract which allows a component to invoke services without knowing implementation or binding details. The picture below shows an example of wiring a reference on the Routing component to a service offered by the Bean component.
