An invaluable resource - from the experts!,
This review is from: Using JRuby: Bringing Ruby to Java (Facets of Ruby) (Paperback)
I had the pleasure of attending JRubyConf in 2010, where I met many of the authors of the book. I was so excited about JRuby (and the quailty of the speakers) it I pre-ordered the book then. I received my printed copy recently, and I couldn't be more pleased with it!
If Ruby or JRuby is in your future (hint: it should be!) don't hesitate to pick this up.
