there is no platform independent way to do this. So read up how you do
it in C++ on platform, then write some JNI glue to it.

See http://mindprod.com/jgloss/jni.html

I am using a program called Copernic that does that. It is wonderful
the way it instantly indexes the files I have recently modified.

It is so much faster than Google Desktop and so much more accurate.

Yet. Change notification is planned as part of the new filesystem
interface classes in NIO2 in Java 7: http://tech.puredanger.com/java7#jsr203

Maybe you wanna take a look to Jnotify (http://jnotify.sourceforge.net/).

It seems to work on recent Linux and Windows using native Syscalls.
