Narrative:
Turned over to ewr tower by approach. Checked in with tower and cleared to land runway 22L. Tower advised of helicopter departing. Saw helicopter on TCASII but not visually. Continued on approach with autoplt flying aircraft on ILS. Received RA from TCASII and kicked autoplt off and responded. Helicopter passed at 400 ft under us. He had us visually throughout event, but by procedure we are required to respond to RA. Such a maneuver is alarming to passenger and certainly not very safe at 800-1000 ft on final. Suggest the published helicopter departure be changed to put them much further below GS for approach.
