Rails 2.1 on GlassFish - it works!

• Identical Development and Deployment environment
• Multiple Applications can be deployed on one Container
• Multiple requests can be handled by a single application (with no extra configuration)
• Out-of-the-box Clustering, Load Balancing and High Availability
• Database connection pooling
• Co-hosting Rails and Java EE applications

1. Install Rails 2.1 in a JRuby 1.1.2 installation:
   
   

   ~/testbed/rails21/jruby-1.1.2 >bin/jruby -S gem install rails --no-ri --no-rdoc JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Updating metadata for 253 gems from http://gems.rubyforge.org/ ............................................................................... ............................................................................... ............................................................................... ................ complete Bulk updating Gem source index for: http://gems.rubyforge.org/ 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 6 gems installed

2. Create a new Rails app as:
   
   

   ~/testbed/rails21/jruby-1.1.2/samples/rails >../../bin/jruby -S rails -d mysql runner       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  lib       create  lib/tasks       create  log       create  public/images       create  public/javascripts       create  public/stylesheets       create  script/performance       create  script/process       create  test/fixtures       create  test/functional       create  test/integration       create  test/unit       create  vendor       create  vendor/plugins       create  tmp/sessions       create  tmp/sockets       create  tmp/cache       create  tmp/pids       create  Rakefile       create  README       create  app/controllers/application.rb       create  app/helpers/application_helper.rb       create  test/test_helper.rb       create  config/database.yml       create  config/routes.rb       create  config/initializers/inflections.rb       create  config/initializers/mime_types.rb       create  config/initializers/new_rails_defaults.rb       create  config/boot.rb       create  config/environment.rb       create  config/environments/production.rb       create  config/environments/development.rb       create  config/environments/test.rb       create  script/about       create  script/console       create  script/dbconsole       create  script/destroy       create  script/generate       create  script/performance/benchmarker       create  script/performance/profiler       create  script/performance/request       create  script/process/reaper       create  script/process/spawner       create  script/process/inspector       create  script/runner       create  script/server       create  script/plugin       create  public/dispatch.rb       create  public/dispatch.cgi       create  public/dispatch.fcgi       create  public/404.html       create  public/422.html       create  public/500.html       create  public/index.html       create  public/favicon.ico       create  public/robots.txt       create  public/images/rails.png       create  public/javascripts/prototype.js       create  public/javascripts/effects.js       create  public/javascripts/dragdrop.js       create  public/javascripts/controls.js       create  public/javascripts/application.js       create  doc/README_FOR_APP       create  log/server.log       create  log/production.log       create  log/development.log       create  log/test.log

3. Start GlassFish as:
   
   

   ~/testbed/glassfish/v3/tp2/glassfishv3-tp2/glassfish >java -DJRUBY_HOME=/Users/arungupta/testbed/rails21/jruby-1.1.2 -jar modules/glassfish-10.0-tp-2-SNAPSHOT.jar Jun 17, 2008 6:14:21 PM com.sun.enterprise.glassfish.bootstrap.ASMain main INFO: Launching GlassFish on HK2 platform Jun 17, 2008 6:14:22 PM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 8080 Jun 17, 2008 6:14:22 PM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 8181 Jun 17, 2008 6:14:22 PM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 4848 Jun 17, 2008 6:14:22 PM com.sun.enterprise.v3.admin.adapter.AdminConsoleAdapter setContextRoot INFO: Admin Console Adapter: context root: /admin Jun 17, 2008 6:14:22 PM com.sun.enterprise.v3.server.AppServerStartup run INFO: Glassfish v3 started in 974 ms

4. Deploy the newly created application as:
   
   

   ~/testbed/rails21/jruby-1.1.2/samples/rails >~/testbed/glassfish/v3/tp2/glassfishv3-tp2/glassfish/bin/asadmin deploy runner Command deploy executed successfully.

   
   and the GlassFish console shows:
   
   

   Jun 17, 2008 6:14:41 PM com.sun.enterprise.rails.RailsDeployer registerAdapter INFO: Loading application runner at /runner Jun 17, 2008 6:14:41 PM   INFO: Starting Rails instances Jun 17, 2008 6:14:49 PM   SEVERE: JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Jun 17, 2008 6:14:51 PM com.sun.grizzly.jruby.RubyObjectPool$1 run INFO: Rails instance instantiation took : 9066ms Jun 17, 2008 6:14:51 PM com.sun.enterprise.v3.deployment.DeployCommand execute INFO: Deployment of runner done is 9168 ms

   
   The default page at "http://localhost:8080/runner" shows
   
   
   
5. Generate a Scaffold as described in TOTD #28
   
   

   ~/testbed/rails21/jruby-1.1.2/samples/rails/runner >../../../bin/jruby -S rake db:create (in /Users/arungupta/testbed/rails21/jruby-1.1.2/samples/rails/runner) ~/testbed/rails21/jruby-1.1.2/samples/rails/runner >../../../bin/jruby script/generate scaffold distance miles:float run_at:datetime 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/distances       exists  app/views/layouts/       exists  test/functional/       exists  test/unit/       exists  public/stylesheets/       create  app/views/distances/index.html.erb       create  app/views/distances/show.html.erb       create  app/views/distances/new.html.erb       create  app/views/distances/edit.html.erb       create  app/views/layouts/distances.html.erb       create  public/stylesheets/scaffold.css       create  app/controllers/distances_controller.rb       create  test/functional/distances_controller_test.rb       create  app/helpers/distances_helper.rb        route  map.resources :distances   dependency  model       exists    app/models/       exists    test/unit/       exists    test/fixtures/       create    app/models/distance.rb       create    test/unit/distance_test.rb       create    test/fixtures/distances.yml       create    db/migrate       create    db/migrate/20080618012326_create_distances.rb ~/testbed/rails21/jruby-1.1.2/samples/rails/runner >../../../bin/jruby -S rake db:migrate (in /Users/arungupta/testbed/rails21/jruby-1.1.2/samples/rails/runner) == 20080618012326 CreateDistances: migrating ================================== -- create_table(:distances)    -> 0.0080s == 20080618012326 CreateDistances: migrated (0.0090s) =========================

6. Edit line 44 of "config/environment.rb" to change the default timezone from "UTC" to "Pacific Time (US & Canada)". The updated line looks like:
   
   

   config.time_zone = 'Pacific Time (US & Canada)'

7. Creating a new scaffold entry shows the following screen:
   
   
   
   Notice how default timezone is selected using Rails 2.1 Time Zone Support. After creating couple of entries (as described in TOTD #28), the page at "http://localhost:8080/runner/distances" looks like:
   
   
   
   Notice how "-0700" is shown which is the offset for US Pacific Time during daylight savings.
   

1. Install GlassFish v3 Gem as:
   
   

   ~/testbed/rails21/jruby-1.1.2 >bin/jruby -S gem install glassfish JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Updating metadata for 13 gems from http://gems.rubyforge.org/ ............. complete Successfully installed glassfish-0.2.0-universal-java 1 gem installed

2. Deploy the previously created Rails application as:
   
   

   ~/testbed/rails21/jruby-1.1.2/samples/rails >../../bin/jruby -S glassfish_rails runner Jun 17, 2008 6:39:37 PM com.sun.enterprise.glassfish.bootstrap.ASMain main INFO: Launching GlassFish on HK2 platform Jun 17, 2008 6:39:37 PM com.sun.enterprise.glassfish.bootstrap.ASMainHK2 findDerbyClient INFO: Cannot find javadb client jar file, jdbc driver not available Jun 17, 2008 6:39:38 PM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3000 Jun 17, 2008 6:39:38 PM com.sun.enterprise.v3.services.impl.GrizzlyEmbeddedHttpConfigurator configureSSL WARNING: pewebcontainer.all_ssl_protocols_disabled Jun 17, 2008 6:39:38 PM com.sun.enterprise.v3.services.impl.GrizzlyEmbeddedHttpConfigurator configureSSL WARNING: pewebcontainer.all_ssl_ciphers_disabled Jun 17, 2008 6:39:38 PM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3131 Jun 17, 2008 6:39:38 PM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3838 Jun 17, 2008 6:39:39 PM com.sun.enterprise.v3.admin.adapter.AdminConsoleAdapter setContextRoot INFO: Admin Console Adapter: context root: /admin Jun 17, 2008 6:39:39 PM com.sun.enterprise.rails.RailsDeployer registerAdapter INFO: Loading application runner at / Jun 17, 2008 6:39:39 PM  INFO: Starting Rails instances Jun 17, 2008 6:39:44 PM  SEVERE: JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Jun 17, 2008 6:39:45 PM com.sun.grizzly.jruby.RubyObjectPool$1 run INFO: Rails instance instantiation took : 6710ms Jun 17, 2008 6:39:45 PM com.sun.enterprise.v3.server.AppServerStartup run INFO: Glassfish v3 started in 8053 ms

   
   The page at "http://localhost:3000/runner" looks like:
