External Callouts or Invoking Services from a BPEL Process

Calling out to web services or other components is the most natural thing for a BPEL process. The Invoke activity is used for making such calls. And just like the Receive and Reply are associated with a partner link, so is the Invoke. The partner link represents the service interface that the invoke calls out to – without bothering the invoke activity with details about transport or location.

Ìn this section, we add a call from the FlightScheduleService BPEL process to the SlotService.
