We had a similar requirement (though with nested subfolders). If you
just have a flat folder to watch (i.e. not subfolders), on OS X you
can use KQueue's to notify you (you can do it with subfolders too,
but it's harder, and I'm not sure of the performance implications as
the # of subfolders increases) and open a connection to your direct
action when you receive a kqueue event. I never ended up using it,
but JNIWrapper (http://www.jniwrapper.com/) provides a java wrapper
around this behavior (kqueue on OS X, the equivalent on Windows) in
their FileSystemWatcher clas -- can't vouch for it personally, though.

Hi,
I was told this is "easy" and will work, because the file system is
capable of this:
Someone puts a file into a folder of the webserver.
This "putting a new File into the folder" triggers a action of the
woapp (how ever), probably a direct action, to read in this file
into a database (a textFile). So in place of a WOTimer or Timer the
file system notifies the App when a new file is there and the app
then starts the process it is supposed to do with the file.
Is this possible at all? If yes, how? Is it advisable if possible?
Can one define it such that only specific files would trigger the
action?
Thanks for some comments.
Regards,
Ute
