JRuby 1.1.3 was released last week - download here. The highlights are:

• 82 issues resolved since JRUby 1.1.2
• RubyGem 1.2 (phew, finally Gem installation is much faster again :)
• Bunch of Compatibility and Performance problems

Going forward, JRuby point releases will be on a 3-4 week frequency. And you can always checkout the trunk and build yourself.

Here are few simple steps to get you started:

1. Download and unzip the distribution.
2. Install Rails and GlassFish gem:
   
   

   ~/testbed/jruby-1.1.3 >./bin/jruby -S gem install rails glassfish --no-ri --no-rdoc JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Successfully installed activesupport-2.1.0 Successfully installed activerecord-2.1.0 Successfully installed actionpack-2.1.0 Successfully installed actionmailer-2.1.0 Successfully installed activeresource-2.1.0 Successfully installed rails-2.1.0 Successfully installed glassfish-0.3.1-universal-java 7 gems installed

3. Create a new Rails app as:
   
   

   ~/testbed/jruby-1.1.3/samples/rails >../../bin/jruby -S rails helloworld -d mysql        create        create  app/controllers       create  app/helpers       create  app/models       create  app/views/layouts       create  config/environments       create  config/initializers       create  db       create  doc . . .       create  log/server.log       create  log/production.log       create  log/development.log       create  log/test.log

4. Run Rails application on GlassFish gem as:
   
   

   ~/testbed/jruby-1.1.3/samples/rails >../../bin/jruby -S glassfish_rails helloworld Jul 21, 2008 8:32:03 AM com.sun.enterprise.glassfish.bootstrap.ASMain main INFO: Launching GlassFish on HK2 platform Jul 21, 2008 8:32:03 AM com.sun.enterprise.glassfish.bootstrap.ASMainHK2 findDerbyClient INFO: Cannot find javadb client jar file, jdbc driver not available Jul 21, 2008 8:32:04 AM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3000 Jul 21, 2008 8:32:04 AM com.sun.enterprise.v3.services.impl.GrizzlyEmbeddedHttpConfigurator configureSSL WARNING: pewebcontainer.all_ssl_protocols_disabled Jul 21, 2008 8:32:04 AM com.sun.enterprise.v3.services.impl.GrizzlyEmbeddedHttpConfigurator configureSSL WARNING: pewebcontainer.all_ssl_ciphers_disabled Jul 21, 2008 8:32:04 AM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3131 Jul 21, 2008 8:32:04 AM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3838 Jul 21, 2008 8:32:04 AM com.sun.enterprise.v3.admin.adapter.AdminConsoleAdapter setContextRoot INFO: Admin Console Adapter: context root: /admin Jul 21, 2008 8:32:05 AM com.sun.grizzly.jruby.RailsAdapter startRubyRuntimePool INFO: Starting Rails instances Jul 21, 2008 8:32:09 AM  SEVERE: JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Jul 21, 2008 8:32:10 AM com.sun.grizzly.jruby.RubyObjectPool$1 run INFO: JRuby and Rails instance instantiation took : 5623ms Jul 21, 2008 8:32:10 AM org.glassfish.scripting.rails.RailsDeployer load INFO: Loading application helloworld at / Jul 21, 2008 8:32:10 AM com.sun.enterprise.v3.server.AppServerStartup run INFO: Glassfish v3 started in 7046 ms

5. Create a scaffold as:



~/testbed/jruby-1.1.3/samples/rails/helloworld >../../../bin/jruby script/generate scaffold runner distance:float minutes:integer JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL       exists  app/models/       exists  app/controllers/       exists  app/helpers/       create  app/views/runners       exists  app/views/layouts/       exists  test/functional/       exists  test/unit/       exists  public/stylesheets/       create  app/views/runners/index.html.erb       create  app/views/runners/show.html.erb       create  app/views/runners/new.html.erb       create  app/views/runners/edit.html.erb       create  app/views/layouts/runners.html.erb       create  public/stylesheets/scaffold.css       create  app/controllers/runners_controller.rb       create  test/functional/runners_controller_test.rb       create  app/helpers/runners_helper.rb        route  map.resources :runners   dependency  model       exists    app/models/       exists    test/unit/       exists    test/fixtures/       create    app/models/runner.rb       create    test/unit/runner_test.rb       create    test/fixtures/runners.yml       create    db/migrate       create    db/migrate/20080721153737_create_runners.rb

6. Start MySQL database, create and migrate the database:
   
   

   ~/testbed/jruby-1.1.3/samples/rails/helloworld >../../../bin/jruby -S rake db:create (in /Users/arungupta/testbed/jruby-1.1.3/samples/rails/helloworld) ~/testbed/jruby-1.1.3/samples/rails/helloworld >../../../bin/jruby -S rake db:migrate (in /Users/arungupta/testbed/jruby-1.1.3/samples/rails/helloworld) == 20080721154435 CreateRunners: migrating ==================================== -- create_table(:runners)    -> 0.0097s == 20080721154435 CreateRunners: migrated (0.0104s) ===========================

   
   Now "http://localhost:3000/runners" page is shown as:
   
   
   
   After adding couple of entries, the page looks like:
   
   
   
   Now, let's try to run the same application on GlassFish v3 stand-alone build.
   
   TOTD #33 explains how to build GlassFish v3 workspace. Alternatively nightly or promoted builds can be downloaded as well.
   
   
7. Start the v3 server as:
   
   

   ~/testbed/glassfish/v3/snapshot/glassfish >java -DJRUBY_HOME=/Users/arungupta/testbed/jruby-1.1.3 -jar modules/glassfish-10.0-SNAPSHOT.jar Jul 21, 2008 9:40:41 AM com.sun.enterprise.glassfish.bootstrap.ASMain main INFO: Launching GlassFish on Apache Felix OSGi platform Jul 21, 2008 9:40:41 AM com.sun.enterprise.glassfish.bootstrap.ASMainOSGi getSharedRepos INFO: /Users/arungupta/testbed/glassfish/v3/snapshot/glassfish/domains/domain1/lib does not exist Welcome to Felix. ================= . . . INFO: Started bundle org.glassfish.common.container-common [91] Jul 21, 2008 9:47:13 AM com.sun.enterprise.v3.admin.adapter.AdminConsoleAdapter setContextRoot INFO: Admin Console Adapter: context root: /admin Jul 21, 2008 9:47:13 AM OSGiModuleImpl loadClass INFO: Started bundle org.glassfish.deployment.deployment-common [71] Jul 21, 2008 9:47:13 AM com.sun.enterprise.v3.server.AppServerStartup run INFO: Glassfish v3 started in 1507 ms

8. Deploy the application as:
   
   

   ~/testbed/jruby-1.1.3/samples/rails >~/testbed/glassfish/v3/snapshot/glassfish/bin/asadmin deploy helloworld Command deploy executed successfully.

   
   and the GlassFish console shows the following output:
   
   

   Jul 21, 2008 9:47:49 AM OSGiModuleImpl loadClass INFO: Started bundle org.glassfish.web.war-util [65] Jul 21, 2008 9:47:49 AM OSGiModuleImpl loadClass INFO: Started bundle org.glassfish.persistence.jpa-connector [25] Jul 21, 2008 9:47:49 AM OSGiModuleImpl loadClass INFO: Started bundle org.glassfish.scripting.gf-jruby-connector [13] Jul 21, 2008 9:47:49 AM OSGiModuleImpl loadClass INFO: Started bundle org.glassfish.core.security [22] Jul 21, 2008 9:47:49 AM OSGiModuleImpl loadClass INFO: Started bundle org.glassfish.web.gf-web-connector [86] Jul 21, 2008 9:47:49 AM OSGiModuleImpl loadClass INFO: Started bundle org.glassfish.connectors.gf-connectors-connector [53] Jul 21, 2008 9:47:49 AM com.sun.grizzly.jruby.RailsAdapter startRubyRuntimePool INFO: Starting Rails instances Jul 21, 2008 9:48:01 AM  SEVERE: JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Jul 21, 2008 9:48:02 AM com.sun.grizzly.jruby.RubyObjectPool$1 run INFO: JRuby and Rails instance instantiation took : 12852ms Jul 21, 2008 9:48:02 AM org.glassfish.scripting.rails.RailsDeployer load INFO: Loading application helloworld at /helloworld Jul 21, 2008 9:48:02 AM com.sun.enterprise.v3.deployment.DeployCommand execute INFO: Deployment of helloworld done is 13326 ms


The deployed application at "http://localhost:8080/helloworld/runners" looks like:

Rails powered by the GlassFish Application Server explain in detail about the several benefits of using GlassFish for Rails development and deployment. Rails/GlassFish Deployment Stories gives a good idea of how to structure your own application.
