Yes, there is: JRuby is your answer, I write a ruby app that runs inside
JRuby, it works wery well (but for now I don''t call any Java class
method...).
JRuby is ruby interpreter written in Java and u can use ruby classes
from Java and vice versa.
Now with 1.1 versione (1.1RC2 at this moment) the interpreter can
compile ruby class (ahead of time and just in time), very cool !!!
If you want to run ruby apps inside GlassFish V3 app server give a try
to glassfish gem (
http://rubyforge.org/frs/download.php/32339/glassfish-0.1.1-universal-java-1.5.gem

Sorry, I don''t know...> 3. Alternately, I would consider using Java for the whole project if

The only other project I know is Grails (Groovy based) but if you have
some Ruby/Rails experience the best choice is JRuby... (supported very
well by NetBeans IDE, my best IDE friend since 2001...)
Have a nice day...> Thanks,
