I am using nokogiri in 2 examples in a new Ruby book that I am writing for APress; I had a warning about JRuby incompatibility (and have a little code using a pure Ruby alternative), but by the time the book is published (5 months) it looks like we will have a working version for JRuby. I could be of more help with the pure Java version, so I will as Charles if he wants help.
