Another method, which we usually discuss as the "better" (I put in

whether or not you call the other language program from Java.

That's a very good way to handling complex communication between Java and host programs. I use that when I need to send lists of data back and forth. But I still call a program to populate the data queue.

I use RFML or RecordFormat objects to keep the data structure between native & java code in sync.
