I have inherited an applet, which in the past has allowed the user to FTP image files to and from the internal server. Recently, the server was put behind a firewall, but is still on the intranet. Since it is behind the firewall, I need to start using SFTP for the file transfers. Does anyone have any suggestions of code to use. As a side note, purchasing softeware for this purpose will not be an option, as the app will probably be killed within 18 months and the frequency of the upload/downloads is minimal.
