I have an existing web application written in Ruby using rack and thin. I need to port this to JRuby so that it can interface with some Java libraries. Google pointed me to this page: https://github.com/jruby/jruby/wiki/JRuby_Rack
What is this JRuby-Rack? I don't know enough about Ruby to seem to figure it out and there does not seem to be any tutorials. I do not know what is warble and the only example I have seen involves rails which I am not using.
If there is a less painful way of doing this please let me know.
