I suggest you check with http://www.ainslie-software.com. They have
a very nice tool called AdaJNI which I believe will give you
the ability to call Ada from Java, and perhaps vice-versa.
Note also that you can generally make Ada code "look" like C code
by applying a pragma Convention(C, xxx) to the Ada code, which
should simplify interfacing.

The other choice is to recompile your entire Ada source into
Java byte codes. However, that will definitely reduce performance
of the Ada code to some degree. See http://www.appletmagic.com for
information on that.
