I played 'round with a generator for bindings to
Java classes until:

1. I found out about Ainsley Software's AdaJNI.

2. I did everything I needed with raw JNI using Cafe1815,
   so I no longer had a need for it (beyond satisying my
   own curiosity)

3. I was concerned about the legalities of generating
   a binding using Sun's sources (there is still not
   a free Swing - which was my main interest)

The approach I took was a custom doclet for Javadoc.
This provided me with a known good Java parser.

The only drawback I found in using javadoc was that
the code was written in Java. It would, of course,
be possible to hand build a binding to the doclet
classes so that the doclet could be written in Ada.

I still had some hard problems to overcome, but
if  anybody is interested in seeing what I did,
