I do it all the time, but by logging into machine C and starting an SSH
session on A, from which I run ftp transfers between machines A and B. I
realise this is probably not what you want, but if you supplied bit more
detail that would help people to give more relevant advice. Some
questions:
- what will cause machine C to start the FTP session?
IOW will it be manually started?
Automatically triggered by some sort of timer?
Triggered by some other event?
- what OS(es) are involved?
If Linux, I'd do the lot with bash scripts, standard SSH clients and
servers. I'd use a cron job to run scheduled transfers.
If Windows, I'd do much the same since FOSS FTP and SSH clients and
servers are available and so are 3rd party cron implementations.
- why use FTP rather than SSH?
- if you have to implement it as a set of Java processes there are
Java libraries out there that provide FTP and SSH client code and
also pure Java implementations of FTP and SSH servers, but why
design/write/test Java code when both FTP and SSH clients and servers
are available as free open source packages?

See above.

Indeed.
