A buildpack to fast and easy use JRuby on Heroku. Just create a Heroku app like this:
heroku create -s cedar --buildpack https://github.com/jruby/heroku-buildpack-jruby.git
It will download and unpack JRuby from jruby.org, install Bundler and run bundle install and then use your Procfile.
Example Procfile:
web: bin/trinidad -t -r -p $PORT -e $RACK_ENV
Note: You do normally not want to use bundle exec with JRuby. Use the binstubs (in bin/) instead, and put require 'bundler/setup' before any other require.
Current JRuby version: 1.6.7
For now only supports 1.9 mode, open an issue if you need 1.8 mode.
Example application: github.com/carlhoerberg/heroku-jruby-example
Recommended web servers are:
- Trinidad - A wrapper around Tomcat
- Mizuno - A wrapper around Jetty
- Puma - A server written in Ruby, wraps the Ragel parser (from Mongrel)
