Upload/download files to/from SFTP server

[Chengwei Lee]

I need to upload/down files to/from a UNIX box to a SFTP server. Could I use the FTPClient (Apache commons net) for it?

I also need to use key based authentication. So if I install my public key in the SFTP server, and private key in my UNIX box, would that be sufficient? That is, I need to login from within my application (for file transfer)?

Thanks!
