Joe's stuff is at http://www.net-foundry.com/java/gnu/hylafax/
It's a basic lib a java client can use to communicate with the Faxserver
and a good starting point for your own client.

SuSEFax is a complete java client for HF from SuSE.

I wrote 2 java clients, one of them uses Joe's lib:
http://sourceforge.net/project/showfiles.php?group_id=5469

But they are usefull for production only in certain environments
(one has a gui but cannot send faxes, this is usefull if your app
sends faxes directly; the other one can send faxes but has no gui)
The install-part of the readme needs some updating also.

The trick is to use halyfax's natice client sendfax.
Try sendfax -vv ...

It will display the communication with the server.
