haven't really analyzed your efforts. I've maintained from day one that one
is much better off avoiding calling Java from RPG . My "day one" is from
about 1997 - I'll leave it up to you to decide whether I now have 13 years
of Java experience or one year 13 times. You can check this list for
reasons to avoid JNI. I've never had a situation where it was required.
One benefit, as you've noticed, is large performance gains.
I've started a new topic because I'd like to hear your and others opinion on how our needs might be solved.

We have a situation where we from CL invoke a Java program with RUNJVA/JAVA and pass in parameters through properties and command line arguments. Very nice. Works well.

The problem arising in the horizont is the need to be able to pass back more than just the exit value to the invoking CL program. When I researched the matter on V5R3 Classic JVM it appeared that this could not be done through the RUNJVA/JAVA command.

Would the way to do this, be to follow IBM instructions on how to invoke a JVM, call a given method and parse the returned value and then discard it? I am not comfortable with following that approach and would really prefer not to if any standard CL command could do it easily.

Have anybody worked with the JVM like this and lived to tell the tale?
