Robin, AFAIK the Commons Net doesn't have file monitoring support, but if you need this functionality, check here: http://stackoverflow.com/questions/1096404/is-there-a-sophisticated-file-system-monitor-for-java-which-is-freeware-or-open-sI hope it helps.

A:
There is no FTP command for monitoring a directory. Your application will need to connect, request the directory listing and cache it. Then, periodically, connect, fetch a new listing, and compare it to the cached listing.
Note that FTP servers generally will not let you sit there with an idle connection. So, the proper behavior is to disconnect between checks of the listing.

edtFTPj/PRO is a commercial Java client library that supports SFTP, FTP and FTPS (and SCP).
As another answer notes, you will need to periodically compare the latest listing with the previous one (disconnecting in between attempts).
