Thanks Matt, I was having difficulty getting the serviceIdentifier from
that controller service property defined in my processor, now I got it.

Ben,

Yes, configuring the Processor with a Controller Service is what I meant.
If you define a Property that identifies a Controller Service (for instance
here [1]) the value of that property when accessed through
getComponentDetails will be the serviceIdentifier.
