Calling Java from RPG/COBOL

["Jon Paris" <Jon.Paris@xxxxxxxxxxxxxx>]

 >> I am aware of the garbage collection issue, the use of static/global
variables in the RPG as a pitfall, and the issue of translation of data when
not calling via methods. What other pitfalls are there?

That pretty much covers it Chris - you probably know more about it than I
do.

One thing that fools the RPGers is that  "If A = B" or "Eval A = B" doesn't
mean the same thing if A and B are objects as it does when they are regular
RPG variables.  For non-Java literate RPGers (and even the Java literate who
are in "RPG mode") that can result in interesting debugging issues <grin>

If you are on V5R1 why not use this RPG support?  My current requirement is
for COBOL and for systems at V4R5 or earlier that cannot use the V5 RPG
support which I think is fabulous.  In particular - the ease with which you
can create RPG Native methods is great.  The RPG invoking Java methods is a
"nice to have" but Native methods to me are the real benefit.
