Here's a link to an article on prototyping:
http://www.midrangeserver.com/mpo/mpo013102-story02.html


Here's the RPG page in the Info Center:
http://publib.boulder.ibm.com/iseries/v5r2/ic2924/info/rzahgrpgcode.htm

This page has lots of good information for RPG and Visual Age RPG.
Right-click "WebSphere Development Studio ILE RPG Programmer's Guide"
and download the file (it's pdf format). Look inside chapter 11 to see more
about prototyping Java methods. 

There's also a Java section in the Info Center. Look in the left column menu
under Programming.

Thanks a bunch for the reply. I think I am highly interested in this part.

"Oh, and you can invoke methods in Java classes inside RPG programs. You 
have
to 'prototype' the Java method (i.e., define the Java method inside the RPG
program). Then the RPG program executes the Java method"

and the other way also. In the sense that calling RPG from Java and this is 
the whole purpose of me trying to get a better understanding of RPG.
