Near midair collision between a MD88 on a 15 mi out localizer descending to 3000 ft and a VFR high wing cessna crossing from the 10 O'clock position at 3000 ft. Controller issued an advisory of the VFR traffic at the same time that the flight crew had a TCASII TA and then an RA, to which they responded. The cessna passed underneath the reporter, approximately 300 ft below.

Narrative:
Our aircraft was cleared to track ewr runway 4R localizer and descend to 3000 ft. Autoplt was on tracking localizer (inbound heading 039 degrees). Approach control advised VFR traffic at 11 O'clock at 3000 ft. TCASII issued TA at same time. Initial TA position was 10 O'clock, 2 mi, 400 ft below us. (-04 annotated on yellow diamond.) I, as first officer and PNF, sighted aircraft within a few seconds, a high wing, light, single engine aircraft. Our aircraft was descending through 3300 ft at this time and captain, PF, began immediate climb. TCASII issued a 'climb, climb' RA almost simultaneously. Our aircraft bottomed at 3200 ft before beginning climb, the other aircraft passed directly under us approximately 300 ft. Other aircraft did not appear to maneuver or react to our aircraft at all. When TCASII reported, 'clear of conflict,' we resumed normal approach and landing. The approach controller did ask us to verify the other aircraft's altitude as 3000 ft which we confirmed.

Title: NMAC BTWN A MD88 ON A 15 MI OUT LOC DSNDING TO 3000 FT AND A VFR HIGH WING CESSNA XING FROM THE 10 O'CLOCK POS AT 3000 FT. CTLR ISSUED AN ADVISORY OF THE VFR TFC AT THE SAME TIME THAT THE FLC HAD A TCASII TA AND THEN AN RA, TO WHICH THEY RESPONDED. THE CESSNA PASSED UNDERNEATH THE RPTR, APPROX 300 FT BELOW.
Narrative: OUR ACFT WAS CLRED TO TRACK EWR RWY 4R LOC AND DSND TO 3000 FT. AUTOPLT WAS ON TRACKING LOC (INBOUND HDG 039 DEGS). APCH CTL ADVISED VFR TFC AT 11 O'CLOCK AT 3000 FT. TCASII ISSUED TA AT SAME TIME. INITIAL TA POS WAS 10 O'CLOCK, 2 MI, 400 FT BELOW US. (-04 ANNOTATED ON YELLOW DIAMOND.) I, AS FO AND PNF, SIGHTED ACFT WITHIN A FEW SECONDS, A HIGH WING, LIGHT, SINGLE ENG ACFT. OUR ACFT WAS DSNDING THROUGH 3300 FT AT THIS TIME AND CAPT, PF, BEGAN IMMEDIATE CLB. TCASII ISSUED A 'CLB, CLB' RA ALMOST SIMULTANEOUSLY. OUR ACFT BOTTOMED AT 3200 FT BEFORE BEGINNING CLB, THE OTHER ACFT PASSED DIRECTLY UNDER US APPROX 300 FT. OTHER ACFT DID NOT APPEAR TO MANEUVER OR REACT TO OUR ACFT AT ALL. WHEN TCASII RPTED, 'CLR OF CONFLICT,' WE RESUMED NORMAL APCH AND LNDG. THE APCH CTLR DID ASK US TO VERIFY THE OTHER ACFT'S ALT AS 3000 FT WHICH WE CONFIRMED.
