You might check to see if any 3rd party code does what you already want. Polling is discussed and should be doable pure java at 1.4. The nio implementation of a watchservice for OS X is currently still a polling one as far as I know. No one seems to claim that is great, but...


I think this...
https://stackoverflow.com/questions/494869/file-changed-listener-in-java <https://stackoverflow.com/questions/494869/file-changed-listener-in-java>
lists some possibilities.

If you go native and get a kqueue watch service working please let the list know. I tried one for OS X that I couldn’t get working right. It seemed to deadlock on the ‘many files’ nio test case where kqueue would stop pumping events when the java code waited for more. I could get back to it sometime but have no immediate plans to.
