Hi, For those who might not be aware, rjb is a killer gem for using java classes inside your rails app (or any ruby code). Check it out at: http://rubyforge.org/projects/rjb/ I was able to successfully use it in one of my apps that required some code that is only available in java. And it''s much nicer than having to compile a java app, then shell out using backticks, get back the return
