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.

<sca:component name="Routing">
   <camel:implementation.camel>
      <camel:xml path="route.xml"/>
   </camel:implementation.camel>
   <sca:service name="ServiceA">
      <sca:interface.java interface="org.example.ServiceA"/>
   </sca:service>
   <sca:reference name="ServiceC">
      <sca:interface.java interface="org.example.ServiceC"/>
   </sca:reference>
</sca:component>
