2 Agenda Introduction to RoR What is JRuby? GlassFish overview RoR on GlassFish > GlassFish gem > GlassFish v2 Update Center Module > Why JRuby on GlassFish? > Known Issues > Success Story Q&A Ruby On Rails in GlassFish 2

3 Introduction to RoR Ruby On Rails in GlassFish 3

4 Introduction to RoR RoR is Ruby on Rails Ruby > A dynamic object oriented and open source language Rails > Pure Ruby implementation > Web application framework Develop database backed web applications MVC pattern Generators for Model, View, Controller Easy to use ORM Ruby rake db:migrate Scaffolding Generate model, views and controller for CRUD applications Ruby On Rails in GlassFish 4

5 Rails MVC Browser Controller View Model DB Ruby On Rails in GlassFish 5

6 What is JRuby Ruby On Rails in GlassFish 6

7 What is JRuby? How do you run your Ruby application on the JVM? > Use JRuby 100% pure-java implementation of Ruby language > Ruby > Best of both worlds: Java + Ruby Two-way Interaction > Invoke Java from Ruby > Invoke Ruby from Java (JSR 223) Embed Ruby interpreter in any Java application Ruby On Rails in GlassFish 7

8 What is JRuby? Open-source > Distributed under a tri-license (CPL/GPL/LGPL) Core team 4 developers (3 from Sun) Current release - JRuby 1.1RC2 > Planned 1.1 Ruby On Rails in GlassFish 8

9 JRuby Sample include Java frame = javax.swing.jframe.new("jruby Demo") Ruby On Rails in GlassFish 9

10 JRuby Sample include Java frame = javax.swing.jframe.new("jruby Demo") label = javax.swing.jlabel.new("hello JRuby World!") frame.getcontentpane.add(label) frame.setdefaultcloseoperation(javax.swing.jframe::ex IT_ON_CLOSE) Ruby On Rails in GlassFish 10

11 JRuby Sample include Java frame = javax.swing.jframe.new("jruby Demo") label = javax.swing.jlabel.new("hello JRuby World!") frame.getcontentpane.add(label) frame.setdefaultcloseoperation(javax.swing.jframe::exit_on_close) frame.setsize 200, 100 frame.setvisible(true) Ruby On Rails in GlassFish 11

12 JRuby Sample Ruby On Rails in GlassFish 12

13 GlassFish Ruby On Rails in GlassFish 13

14 What is GlassFish? Open Source > CDDL & GPL v2 Java EE 5 Reference Implementation > Included in Java EE 5 SDK Enterprise Quality > High Availability, Clustering >.NET 3.0 Web services interoperability > World Record Performance Community > Sources, bug DBs, discussions at glassfish.java.net > Roadmaps, Architecture Documents Ruby On Rails in GlassFish 14

15 GlassFish v2 Enterprise ready JavaEE 5 compliant application server > Clustering, Load Balancing, HA,.Net 3.0 Web Services interoperability > Seamless IDE integration NetBeans, Eclipse, Intellij Released Sept 2007 Productized as Sun Java System Application Server 9.1 Ruby On Rails in GlassFish 15

16 GlassFish v3 Small (Kernel < 100k) Fast (Startup in < 1 second) Embeddable (Run in the same VM as IDE) Modular (Java, Ruby, JavaScript,...) Support for upcoming Java EE 6 profiles Currently under development > Technology Preview 2 release expected around May at JavaOne 2008 Ruby On Rails in GlassFish 16

17 RoR vs JRoR on GlassFish Ruby On Rails in GlassFish 17

18 GlassFish v3 Gem Ruby Gem > gem install glassfish > GlassFish server + Grizzly connector for JRuby Adds glassfish_rails in bin directory Green alternative to WEBrick and Mongrel > One command, one process Ruby On Rails in GlassFish 18

19 Demo GlassFish v3 Gem Ruby On Rails in GlassFish 19

20 GlassFish v2 Update Center Module GlassFish Update Center > Add new components > Update existing components JRuby on GlassFish module > JRuby > Goldspike > Rails 1.2.6,... Standalone and Shared WAR Ruby On Rails in GlassFish 20

21 Ruby On Rails in GlassFish 21

22 Demo JRuby Update Center Module Ruby On Rails in GlassFish 22

23 Why JRuby on GlassFish? Java EE is tested deployment platform > Co-host Java EE & RoR apps One command, One instance, one process > Green alternative Database Connection Pooling Hot Deployment > No need to restart container OOTB Clustering and High Availability Ruby On Rails in GlassFish 23

24 Known limitation PermGen Issue > JRuby maps methods from a Ruby class as a Java class > A typical Rails application gets mapped in to hundreds of Java classes > JITs the mapped Java classes in PermGen space What is the solution? > JRuby 1.1 RC2 improved it Cap on number of Ruby methods to be JITted Sharable JITCache among multiple JRuby instance > Configure GlassFish to limit number of JRuby in the JRuby instance pool > DaVinci Machine Ruby On Rails in GlassFish 24

25 More Scripting in GlassFish JRuby/Rails JavaScript on server > Phobos PHP > Java-PHP Bridge > Quercus Upcoming scripting and framework support > Groovy on Grails > Jython/Django Ruby On Rails in GlassFish 25
