During my studies in Computer Networks when I was searching an example about FTP, I’ve found a very important information about the previous protocol: in JRE there’s sun.net.ftp.FtpClient, a class that implements the FTP protocol, but there isn’t any trace of the relative documentation. So I did a little search on Sun official site and now you can see what I’ve found.
