Notes about: JRuby: Calling Java Code From A Rack App And Keeping It In Memory

The following gist are available as support to the answer: JRuby: Calling Java Code From A Rack App And Keeping It In Memory

• StatelessCalculator.java a class used by StatefullCalculator
• StatefulCalculator.java the class shared
• sample_app.rb the sinatra app
• Gemfile This file is used by $ bundle install
• .rvmrc if you use rvm to have a sandboxed gemset and a well defined jruby env.

Sinatra Deployment

rvm use --create jruby-1.6.7@jruby_sinatra
export JRUBY_OPTS=--1.9

root = File.dirname(__FILE__)            # => "."
require File.join( root, 'sample_app' )  # => true
run Sample  # ..in sample_app.rb ..class Sample < Sinatra::Base

# singleton-as-module loaded once, kept in memory
module App
  module Global extend self    
    def calc
      @calc ||= StatefulCalculator.new 
    end
  end
