thanks for your quick reply.

I like this approach, I tried it and it works fine.
This is what I added to the hello_jena.rb JRuby script:
Dir["target/dependency/\*.jar"].each { |jar| require jar }
Dir["target/jena-examples-\*.jar"].each { |jar| require jar }
This is to package and copy all the dependencies to a local directory:
mvn clean package dependency:copy-dependencies
Then I can run the script with:
jruby src/main/jruby/hello_jena.rb

I tried this, but it did not work for me:
ERROR: could not find gem mvn:com.hp.hpl.jena:jena locally or in a repository
(but I probably have an obsolete Ruby/gem installation. Don't worry.)

This rvm (http://beginrescueend.com/)?
I am not sure I'll go down this route... for now. :-)

PS:
I'd like to have similar examples for Scala, Jython and Groovy.
