Thanks for starting this!

You may want to try out another one of the protocols. Some of them from our original JPL repository didn't get ported over to Apache. For example: http://s.apache.org/hJM only shows 2 FTP protocols, but in fact Brian Foster actually implemented 4 of them: * Ftp4CheFtpClient.java * Ftp4CheFtpClientFactory.java * JvFtpClient.java * JvFtpClientFactory.java Are missing from the list. This was due to licensing restrictions with their APIs originally. Doing some research, I see: http://sourceforge.net/projects/ftp4che/ - Stil uses LGPL http://jvftp.sourceforge.net/ - Still uses LGPL One option would be for me to put up the PushPull plugins that use these libraries up on my GitHub account. Better yet, we may want to host them on Apache Extras. When the default CommonsNet and JGlobus plugins don't work for FTP, I find that the above 2 usually work.
