Hey guys, I recently tried to use JRuby with eclipse (with Dynamic
Language Toolkit) but I am a bit confused how to use JRuby with Java.
How do I organize my projects? Apparently I can’t have JRuby script
files in Java Projects and vice versa. Do I need to store them in
separate projects and how can I efficiently work with both languages? I
am trying to learn how to use JRuby with Java and call methods from Java
in Ruby.
I know these are easy questions for users who work with JRuby regularly
but I am still quite new to java and completely new to Ruby, so I am
very grateful for general tips, links and advice.
Thanks for the help. 
Joel,
Would you mind sharing the motivations behind invoking Ruby from Java as
opposed to the other way around?
With respect to project structure I feel like multi-module projects make
sense to me, but I don’t use Eclipse so I don’t know if that is
possible: e.g.
project -
-+ module1-jruby
-+ module2-java
project-files (makefile,build.xml,pom.xml)
Thanks,
Ariel

Actually I wanted to make an UI in java and use ruby scripts from the UI
and therefore invoking ruby from java. I am not particularly shure what
I will do with that later, for now I am trying to learn to script and to
use the scripts in java. I thought about doing smaller statistical
calculations or mathematical modelling, usin fisher equations and
similar methods.
In eclipse, do I need to import the ruby folder as a library?
Apparently I can’t add have a ruby module and java in the same project
and I don’t know what I should do with this.
