Apart from the possibilities others have mentioned, there is also JRuby, which makes it easy to include Java code in a Ruby program. I've used JRuby writing my own Java code for the numerical processing which needs to be fast. I haven't tried using "standard" Java libraries, but I assume that if one can include one's own Java "libraries" in a Ruby program, it shouldn't be too hard to do that with standard Java libraries.
