Yes, the Java Native Interface (JNI) does the trick. You only need an Ada
interface to the JNI which is of course defined in C and not in Ada. I've
already done some simple examples this way on Linux and did not encounter
any serious problems, with the usual exception that having to write such
an interface is a lot of work to do.

It can be any of the two. The JNI supports both directions.
