As a JAVA learning exercise I did implement a partial JDCT. It is like
dct313 (the TCL/TK replacement for the 3.12 and earlier DCT). Thus it
does not draw links between records like capfast and gdct. This JDCT
needs a lot of work before it is ready for use. John Anderson with help
from Soon-Ok Park is starting work to complete JDCT. Their E-mail
addresses are.

JDCT includes a java native interface to the static database access
library (this interface is not complete).

GDCT uses a free c++ library called unidraw (or something like that)
which, as far as we know, is no longer being supported by anyone. This
is not good. 

At APS we have talked about a java replacement for GDCT but have never
started anything. My guess is that this will be a difficult project. I
have never heard of any java class library that provides the features
that unidraw provides. To implement such a class library sounds hard.
