Or you could skip all that and simply use Jacada Connects (I hope
I'm not breaking any list regulations by inserting this shameless
plug).
See http://www.cst.com/ for more.
Best of all - Jacada Connects is itself written in Java!

You can hop in, Shahar - we're just around the corner :)

Nimrod, I don't mind the shameless plugs TOO terribly much provided they match
one of the two following guidelines:

1. They promote FREE software (limited-function is OK, time-bombs are not, to my
way of thinking)
-or-
2. They provide a specific solution to a specific problem

Unfortunately, your reply was a bit incomplete.  Jacada Connects is a one-way
solution, allowing Java to execute legacy programs, which is actually quite easy
with the (FREE) JT400 ProgramCall class or by using PCML (for more information
on PCML, see Don Denoncourt's article in AS/400 NetJava Expert,
www.midrangecomputing.com/anje/99/04).  However, executing a Java class FROM a
legacy program is still a problem, and Jacada Connect doesn't do anything at all
there.  To quote Jacada's website:

"Any tool or application capable of communicating with a Java class can use
Jacada Connects."

So Jacada Connects allows Java applications to execute legacy programs, but not
vice versa.  As I pointed out, this functionality is available for FREE from the
IBM Toolbox.  If Jacada provided a way for RPG program to execute a Java class,
well, THEN I'd be impressed.  Until such a package is available, you'll still
need to use data queues or data areas or something to allow bidirectional calls
to Java from a legacy application.
