Narrative:

On approach into oaj we received clearance from wilmington approach control for the ILS runway 05. We were cleared to descend to 2100 MSL until established. Level at 2100 we received a GPWS terrain warning just prior to the final approach fix. Being in day VMC conditions; I assessed the alert and saw no threat of terrain/obstacles and the first officer and I both agreed that we could safely continue as we were established on the course at the correct altitude; with no terrain or obstacles in our flight path. We landed without further event and advised maintenance control once parked at the gate. In further review of the approach chart; the MSA from the outer marker is 3100 MSL; however; we were established on the final approach course when the alert occurred which led us to determine that it was in fact erroneous. After this event; I will be more cognizant of MSA's. Even though during this event we were where we were supposed to be and there was no real threat; it is imperative to verify possible terrain and obstacles that we might encounter on an approach.
