Since Java is normally interpreted by the JVM, and Ada is normally
compiled to machine code, it is not possible to have a normal binding.

However, there are several options. If you want to write Ada code that
runs on a JVM, and uses all the Sun-defined Java classes, just use an
Ada compiler that targets the JVM (JGNAT or ObjectAda for Java).

There are also utilities that let you call native Ada code from
Java/JVM code.

JGNAT: ftp://cs.nyu.edu/pub/gnat/jgnat

ObjectAda: http://www.aonix.com/ (search for "ObjectAda Java")

Native Ada from Java: don't remember, can't find it.
