Monitor filesystem for changes? Tried Netbeans Filesystems API but no luck...

Anyone know of a good piece of code to monitor a filesystem for changes? I
would like to be able to pass it a file or directory handle and receive
notification when the file is changed, a file is created/renamed/deleted
within the directory, etc. Ideally, if given a directory it would monitor
recursively (reporting changes in subdirectories as well).

I tried the Netbeans Filesystems API:
http://openide.netbeans.org/fs/Library.html

However, it does not seem to detect changes made externally. In other words,
if I monitor a directory within my java app, but add a file to the directory
from outside the java app, it doesn't raise an event for that. If someone is
familiar with

I realize that catching OS filesystem events involves native code, but I'm
okay even just with code that just polls the directory for changes, as long
as I can set the interval.

Any luck?

I'm also searching for this. Both options are OK, but I prefer a (native) implementation that doesn't require polling.
