Background:  Hi.  I have been doing some agent work with Netlogo.  I have been working on agent AI initially implemented in Netlogo but now moved to a Java module that is called by Netlogo.  Netlogo allows this by the use of extensions; you create your java code, put it in a .jar, and then Netlogo calls the .jar.  The approach sort of works but I I'm not the creator of the .jar (just the algorithms) and frankly, I'm not really clear on how the two programs actually communicate.

What I would like to do, is use Processing for the AI module.  The reason is, I want to be able to provide a visualization of what is happening in the AI.  The end result would look like:  Netlogo environment with agents doing their thing in one window and a visualization (sketch) of the thinking process of one agent being delivered in a second window.  What would be desirable is also being able to interact with the AI visualization.

Question:  Has anyone done a Netlogo <--> Processing extension or could anyone provide guidance on how it might be done?

PS - I have worked through "Getting Started with Processing" and am just starting on "Visualizing Data".  I am a very advanced Matlab programmer but Java and OO are not very familiar to me.
