Just for the record, calling Java methods from non-Java programs is done
through Java's JNI (Java Native Interface).  It was always possible to use
JNI from those languages.  What changed in v5r1 was that ILE RPG added
support that made it easy to use JNI.

I think it's possible to make bound calls from MI somehow - if so, you
should be able to call the JNI functions from MI.  (But I can't imagine
anything more nasty to code.)
