Re: Java/RPG interface

[Mike Wills <koldark@xxxxxxxxx>]

In my brief expirience with doing this, once you know how to setup a
program to call a java method, it isn't too hard to do. In a batch
program, I don't think you will notice any slowdown for when the JVM
is starting. Sure it takes a bit longer, but who will notice?

I am sure there are some good examples, I got my example from someone
on the list. I was working on getting a brief tutorial together, but
haven't gotten that far yet. If you want an example, email me offline
and I can send you a couple live subprocedures we are using.
