As I noted in my post, many languages have JNI support, and Perl is no exception. JNI is Java Native Interface, and typically it is implemented via a support library that lets you start a JVM, find a class, get a pointer to a method in a class, craft an array of parameters, and then invoke the function. You can find a "simple" Hello world here:

http://www.devdaily.com/scw/perl/perl-5.8.5/jpl/JNI/JNI.pm.shtml

Contrast this with RPG's ability to directly prototype a Java method using standard D-specs and then invoke that method just like you would any other language. There's really no comparison in ease of use.

Not quite sure what that means, Evan, but I'm trying not to fool anyone! :)

I've never had the need to make it work but perl has some modules that
apparently allow the use of java from within perl code.

RPG may not be dead but this thread ain't fooling nobody....

the platform and say that RPG isn't even a language. Clearly you don't
like the topic of this list, so what do you hope to achieve with your
posts? More to the point, though, is that I don't understand your
comments. Like this one:

Java isn't well integrated (not at all actually).
What is this supposed to mean? On what other platform is Java better
"integrated" and why? Certainly not Microsoft. Heck, prior to RPG I
didn't even know another language that could directly call Java. I mean
you can usually use JNI, but only RPG has direct support for prototyping
functions and methods and invoking them. But in any case, saying Java
isn't well integrated on the IBM i is pretty much the opposite of
reality as far as I can tell.

Please, let's start with this one simple statement and then maybe we can
move on to some of the others.
