Noone on the CVS or CVSNT teams is a Java programmer (to my best
knowledge anyway), and it is a frequent frustration (for at least some
of us) that Java programmers don't simply shell out to the CVS or CVSNT
executable.  CVS runs on almost every operating system that exists -
runs natively that is.  But I know Java programmers like Java.  The
problem is that the java libraries rarely support all the latest
features of CVS, eg: proxies, access control, change sets and much more
- limiting the usefulness of any application that uses them.

That is TortoiseCVS and CVSNT which are both NOT a part of this
newsgroup, if you are interested in TortoiseCVS go to the tortoisecvs
newsgroup, ditto with cvsnt.

SSH authentication can use keys instead of a password (provided the key
is registered with the server and client), youd be better off asking an
SSH or Java programming group I suspect.

CVSNT (free/GPL just like CVS, runs oon Linux, Unix, Windows etc) has
what is known as a CVSGUI protocol which is designed so that a GUI can
"call" cvs and if there is a need to prompt a user for a password, key
or anything else there are special "tokens" that can be interpreted by
the caller to present the messages.  This is the better approach IMHO.
