Narrative:

At the time of the incident I had been cleared for the RNAV 21 approach. I entered VMC after passing the IAF and contacted raleigh approach to cancel my IFR flight plan. Raleigh confirmed my cancellation and approved me to change to the CTAF frequency. Ceiling was around 2;500 feet MSL. I announced on the CTAF frequency that I was 8 miles out on the GPS approach for runway 21 at jnx. I made an announcement that I was 5 miles out on the GPS approach for runway 21 at jnx. At this time another pilot made announcement that he was overflying the tank farm 4 miles away and would be passing the approach end of runway 21. I made an announcement that I was 3 miles out on the GPS approach for runway 21 at jnx. The other pilot announced that he had me in sight and would maintain visual separation. I had just passed cumut. It was after this when I saw a cessna disappear underneath my nose. I immediately executed a steep climbing turn to the left to avoid the airplane and announced my intentions on the CTAF. I completed a 360 degree turn and landed on runway 21 without further incident.
