Alessio The onScheduled() is only called once when processor is started. Started means scheduled to execute, hence the name of the operation. When the process is scheduled its scheduler triggers the execution of the processor and the same scheduler controls how often the onTrigger is called. For example, with default TimeDrivenScheduler set to 1 sec, the onTrigger() operation will be invoked every sec.
So to answer your question in short your use case should be implemented in onTrigger(). However onSchedule() is where you could/should obtain the reference to your service. Does that clarify?
