Here are some ways to interact with Java from Ruby, though I can't say 
which is the most stable:

* JRuby: http://jruby.sourceforge.net/

* RJB: http://arton.no-ip.info/collabo/backyard/?RubyJavaBridge

* RJNI: http://thekode.net/ruby/rjni/index.html

Personally, I'd just use Java, or a more Java-compatible scripting 
language like Beanshell (http://beanshell.org) or Groovy 
(http://groovy.codehaus.org/).  I like Ruby, but I don't see the point 
of jumping through hoops to use it for everything unless you need to 
integrate some existing Ruby and Java code.
