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.
