TOTD #37: SQLite3 with Ruby-on-Rails on GlassFish Gem

The default database for Rails 2.0.x application is SQLite3. This database is bundled with Mac OSX Leopard and so makes it really easy to get started with Ruby-on-Rails. But it requires couple of additional steps if you are using JRuby.

TOTD #28 explains how to create a simple CRUD application using Rails 2.0.x. It uses MySQL database which is strongly recommended for deployment. This TOTD (Tip Of The Day) provides complete steps to run a Ruby-on-Rails application using JRuby and GlassFish Gem with the default database, i.e. SQLite3.

1. Create a Rails application as:
   
   

   ~/samples/jruby >~/testbed/jruby-1.1.2/bin/jruby -S rails runner       create        create  app/controllers       create  app/helpers       create  app/models       create  app/views/layouts . . .       create  log/server.log       create  log/production.log       create  log/development.log       create  log/test.log

   
   The generated "database.yml" looks like:
   
   

   # SQLite version 3.x #   gem install sqlite3-ruby (not necessary on OS X Leopard) development:   adapter: sqlite3   database: db/development.sqlite3   timeout: 5000 # Warning: The database defined as "test" will be erased and # re-generated from your development database when you run "rake". # Do not set this db to the same as development or production. test:   adapter: sqlite3   database: db/test.sqlite3   timeout: 5000 production:   adapter: sqlite3   database: db/production.sqlite3   timeout: 5000

2. SQLite3 adapter is installed for the native Ruby bundled with Leopard. But in order to use SQLite3 with JRuby, you need to install SQLite3 JDBC adapter as shown below:
   
   

   ~/samples/jruby/runner >~/testbed/jruby-1.1.2/bin/jruby -S gem install activerecord-jdbcsqlite3-adapter JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Successfully installed activerecord-jdbc-adapter-0.8.2 Successfully installed jdbc-sqlite3-3.5.8 Successfully installed activerecord-jdbcsqlite3-adapter-0.8.2 3 gems installed Installing ri documentation for activerecord-jdbc-adapter-0.8.2... Installing ri documentation for jdbc-sqlite3-3.5.8... Installing ri documentation for activerecord-jdbcsqlite3-adapter-0.8.2... Installing RDoc documentation for activerecord-jdbc-adapter-0.8.2... Installing RDoc documentation for jdbc-sqlite3-3.5.8... Installing RDoc documentation for activerecord-jdbcsqlite3-adapter-0.8.2...

3. Create a new file as "db/development.sqlite3". It can be easily created using the "touch" command. See the beauty of SQLite that "db:create" is not required :)
4. Update the development section of "database.yml" such that it looks like:
   
   

   development:   adapter: jdbcsqlite3   database: db/jdbc:sqlite:development.sqlite3   timeout: 5000

5. Create a simple scaffold as shown below:
   
   

   ~/samples/jruby/runner >~/testbed/jruby-1.1.2/bin/jruby script/generate scaffold run 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/runs       exists  app/views/layouts/       exists  test/functional/       exists  test/unit/       exists  public/stylesheets/       create  app/views/runs/index.html.erb       create  app/views/runs/show.html.erb       create  app/views/runs/new.html.erb       create  app/views/runs/edit.html.erb       create  app/views/layouts/runs.html.erb       create  public/stylesheets/scaffold.css       create  app/controllers/runs_controller.rb       create  test/functional/runs_controller_test.rb       create  app/helpers/runs_helper.rb        route  map.resources :runs   dependency  model       exists    app/models/       exists    test/unit/       exists    test/fixtures/       create    app/models/run.rb       create    test/unit/run_test.rb       create    test/fixtures/runs.yml       create    db/migrate       create    db/migrate/20080630211244_create_runs.rb

   
   and run the migration as
   
   

   ~/samples/jruby/runner >~/testbed/jruby-1.1.2/bin/jruby -S rake db:migrate (in /Users/arungupta/samples/jruby/runner) == 20080630205502 CreateRuns: migrating ======================================= -- create_table(:runs)    -> 0.0410s    -> 0 rows == 20080630205502 CreateRuns: migrated (0.0420s) ==============================

6. A Rails application is deployed on GlassFish from it's parent directory. Therefore the application needs to be updated so taht exact location of database is specified. Basically you need to edit "database.yml" and the updated "development" fragment looks like:
   
   

   development:   adapter: jdbcsqlite3   database: runner/db/jdbc:sqlite:development.sqlite3   timeout: 5000

7. Run the application on GlassFish v3 gem as:
   
   

   ~/samples/jruby >~/testbed/jruby-1.1.2/bin/jruby -S glassfish_rails runner Jun 30, 2008 1:52:08 PM com.sun.enterprise.glassfish.bootstrap.ASMain main INFO: Launching GlassFish on HK2 platform Jun 30, 2008 1:52:08 PM com.sun.enterprise.glassfish.bootstrap.ASMainHK2 findDerbyClient INFO: Cannot find javadb client jar file, jdbc driver not available Jun 30, 2008 1:52:09 PM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3000 Jun 30, 2008 1:52:09 PM com.sun.enterprise.v3.services.impl.GrizzlyEmbeddedHttpConfigurator configureSSL WARNING: pewebcontainer.all_ssl_protocols_disabled Jun 30, 2008 1:52:09 PM com.sun.enterprise.v3.services.impl.GrizzlyEmbeddedHttpConfigurator configureSSL WARNING: pewebcontainer.all_ssl_ciphers_disabled Jun 30, 2008 1:52:09 PM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3131 Jun 30, 2008 1:52:09 PM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3838 Jun 30, 2008 1:52:09 PM com.sun.enterprise.v3.admin.adapter.AdminConsoleAdapter setContextRoot INFO: Admin Console Adapter: context root: /admin Jun 30, 2008 1:52:09 PM com.sun.grizzly.jruby.RailsAdapter startRubyRuntimePool INFO: Starting Rails instances Jun 30, 2008 1:52:16 PM   SEVERE: JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Jun 30, 2008 1:52:17 PM com.sun.grizzly.jruby.RubyObjectPool$1 run INFO: JRuby and Rails instance instantiation took : 7998ms Jun 30, 2008 1:52:17 PM org.glassfish.scripting.rails.RailsDeployer load INFO: Loading application runner at / Jun 30, 2008 1:52:17 PM com.sun.enterprise.v3.server.AppServerStartup run INFO: Glassfish v3 started in 9430 ms

After adding couple of entries, "http://localhost:3000/runs" looks like:



So now you can use SQLite3 as your development database for Rails applications running on GlassFish v3 Gem.

Here are some useful pointers:

• Running Rails with ActiveRecord-JDBC
• SQLite3 man page provides complete set of commands for this database.
• GlassFish v3 Gem 0.3.1
• Rails powered by the GlassFish Application Server
• Getting Started with JRuby on GlassFish

Please leave suggestions on other TOTD (Tip Of The Day) that you'd like to see. A complete archive is available here.

Rails GlassFish Gem 0.3.1 now available

Vivek released 0.3.0 version of GlassFish Gem for Rails (a total of 11 issues fixed and resolved - RubyForge & GlassFish Issue Tracker) earlier. But that caused a regression on #4228. And so matching the agility expected by Rails developers, he quickly released 0.3.1. And a wee bit smaller too - 2.68MB for 0.3.1 instead of 2.69MB for 0.3.0.

If you have an existing version of the gem, then you just need to update it:

~/testbed/jruby-1.1 >bin/jruby -S gem update glassfish -r JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Updating installed gems... Bulk updating Gem source index for: http://gems.rubyforge.org Attempting remote update of glassfish Successfully installed glassfish-0.3.1-universal-java 1 gem installed Gems updated: glassfish

If the gem has never been installed, then you install it as:

~/testbed/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 Successfully installed glassfish-0.3.1-universal-java 1 gem installed

And make sure next time you have to update the gem instead of installing from scratch ;) For that, just install the gem this time and let us know your feedback on GlassFish Webtier Forum or Webtier Alias. If any of your Rails application do not work then please file bugs at GlassFish Issue Tracker ("V3" as "Found in Version:" and "jruby" as "Subcomponent:").

The gem installation may require to set "JAVA_MEM=-Xmx800m" because of the growing memory requirements. Otherwise you may get "Exception in thread "main" java.lang.OutOfMemoryError: Java heap space".

Try a simple scaffold application to see the output as shown below:


The startup output in the gem console (output from GlassFish) is:

~/testbed/jruby-1.1.2/samples/rails >../../bin/jruby -S glassfish_rails runner Jun 24, 2008 11:04:51 PM com.sun.enterprise.glassfish.bootstrap.ASMain main INFO: Launching GlassFish on HK2 platform Jun 24, 2008 11:04:51 PM com.sun.enterprise.glassfish.bootstrap.ASMainHK2 findDerbyClient INFO: Cannot find javadb client jar file, jdbc driver not available Jun 24, 2008 11:04:52 PM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3000 Jun 24, 2008 11:04:52 PM com.sun.enterprise.v3.services.impl.GrizzlyEmbeddedHttpConfigurator configureSSL WARNING: pewebcontainer.all_ssl_protocols_disabled Jun 24, 2008 11:04:52 PM com.sun.enterprise.v3.services.impl.GrizzlyEmbeddedHttpConfigurator configureSSL WARNING: pewebcontainer.all_ssl_ciphers_disabled Jun 24, 2008 11:04:52 PM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3131 Jun 24, 2008 11:04:52 PM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3838 Jun 24, 2008 11:04:52 PM com.sun.enterprise.v3.admin.adapter.AdminConsoleAdapter setContextRoot INFO: Admin Console Adapter: context root: /admin Jun 24, 2008 11:04:52 PM com.sun.grizzly.jruby.RailsAdapter startRubyRuntimePool INFO: Starting Rails instances Jun 24, 2008 11:04:58 PM  SEVERE: JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Jun 24, 2008 11:04:59 PM com.sun.grizzly.jruby.RubyObjectPool$1 run INFO: JRuby and Rails instance instantiation took : 6600ms Jun 24, 2008 11:04:59 PM org.glassfish.scripting.rails.RailsDeployer load INFO: Loading application runner at / Jun 24, 2008 11:04:59 PM com.sun.enterprise.v3.server.AppServerStartup run INFO: Glassfish v3 started in 7945 ms

and then the console is updated as more entries are added (output from Rails):

Redmine seems to have issues with Rails 2.1. I'll play with some other applications later. But have you tried deploying your Rails application on GlassFish gem ? As mentioned above, let us know your feedback on GlassFish Webtier Forum or Webtier Alias and file bugs on GlassFish Issue Tracker.

Details about previous versions are available at 0.2.0, 0.1.2, 0.1.1, 0.1.0.

Rails 2.1 on GlassFish - it works!

Rails 2.1 was released earlier this month. GlassFish provides a complete development/deployment environment for Rails applications. Some of the main reasons for using GlassFish (instead of WEBrick or Mongrel) are:

• 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

More details are available in Rails powered by the GlassFish Application Server. This blog provides detailed instructions to get started with Rails 2.1 on GlassFish.

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.
   

The same application can also be easily deployed on GlassFish v3 Gem. Let's see how:

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:
   
   
   

Let us know on GlassFish Webtier Forum or Webtier Alias if you tried any of your Rails application on GlassFish. Please file bugs at GlassFish Issue Tracker ("V3" as "Found in Version:" and "jruby" as "Subcomponent:") if your app is not working.

... and now host any of your Rails application on v3 Gem (such as Redmine) ...

~/testbed/redmine >../jruby-1.1.2/bin/jruby -S glassfish_rails redmine-0.7 May 28, 2008 12:07:19 PM com.sun.enterprise.glassfish.bootstrap.ASMain main INFO: Launching GlassFish on HK2 platform May 28, 2008 12:07:19 PM com.sun.enterprise.glassfish.bootstrap.ASMainHK2 findDerbyClient INFO: Cannot find javadb client jar file, jdbc driver not available May 28, 2008 12:07:20 PM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3000 May 28, 2008 12:07:20 PM com.sun.enterprise.v3.services.impl.GrizzlyEmbeddedHttpConfigurator configureSSL WARNING: pewebcontainer.all_ssl_protocols_disabled May 28, 2008 12:07:20 PM com.sun.enterprise.v3.services.impl.GrizzlyEmbeddedHttpConfigurator configureSSL WARNING: pewebcontainer.all_ssl_ciphers_disabled May 28, 2008 12:07:20 PM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3131 May 28, 2008 12:07:20 PM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3838 May 28, 2008 12:07:21 PM com.sun.enterprise.v3.admin.adapter.AdminConsoleAdapter setContextRoot INFO: Admin Console Adapter: context root: /admin May 28, 2008 12:07:21 PM com.sun.enterprise.rails.RailsDeployer registerAdapter INFO: Loading application redmine-0.7 at / May 28, 2008 12:07:21 PM  INFO: Starting Rails instances May 28, 2008 12:07:26 PM  SEVERE: JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL May 28, 2008 12:07:32 PM com.sun.grizzly.jruby.RubyObjectPool$1 run INFO: Rails instance instantiation took : 11481ms May 28, 2008 12:07:32 PM com.sun.enterprise.v3.server.AppServerStartup run INFO: Glassfish v3 started in 12787 ms

Below is the screenshot from a previously deployed Redmine application, now on the GlassFish gem:



Simple isn't it ?

If your Rails application does not work on the gem, file bugs here with "jruby" as "subcomponent" (default version is "v3").

Alternatively, you can download GlassFish v3 TP2 and deploy your applications to leverage complete Java EE functionality.

You can also configure JRuby 1.1.2 as a Ruby platform in NetBeans 6.1 as described in TOTD #27.

GlassFish v3 Gem 0.2.0 released

A newer version of GlassFish v3 Gem for Ruby on Rails is now available.

What's new ?

• Codebase aligned with GlassFish v3 Technology Preview 2
• Previous version (0.1.2) had some packaging issues which increased the size but now it's back to sweet 2.8 Mb.

Check if previously installed by using the following command:

~/testbed/jruby-1.1.1 >bin/jruby -S gem list glassfish *** LOCAL GEMS *** glassfish (0.1.2)

If already installed (as indicated by the list of gems) then uinstall it using the following command:

~/testbed/jruby-1.1.1 >bin/jruby -S gem uninstall glassfish Successfully uninstalled glassfish-0.1.2-universal-java Remove executables:         glassfish_rails, asadmin, asadmin.bat in addition to the gem? [Yn]  y Removing glassfish_rails Removing asadmin Removing asadmin.bat

And then install it again as:

~/testbed/jruby-1.1.1 >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 Successfully installed glassfish-0.2.0-universal-java 1 gem installed

Updating the gem is giving unpredictable results (mostly not updating) and will be investigated later.

Rails powered by the GlassFish Application Server explains why GlassFish is a better deployment option for Rails applications.

All the latest information about the gem can be found at GlassFish JRuby wiki or JRuby wiki.

Please use the gem and send us feedback on GlassFish forums, dev@glassfish or gem mailing list.

JRuby 1.1 released - ready for production!

JRuby 1.1 is released and ready for production use today. You can unleash the potential in 3 simple steps - download, unzip & get started. Here is a quote from the announcement:

more and more reports of applications exceeding Ruby 1.8.6 performance; we are even beating Ruby 1.9 in some microbenchmarks

This is validated by 1 (Oct 2007), 2 (Nov 2007), 3 (Feb 2008), 4 (Feb 2008) and many other hidden/unknown reports. You can easily configure JRuby 1.1 as the platform of your choice in NetBeans 6.1 as described in TOTD #27.

Now, match this blazing performance of JRuby with GlassFish v3 gem (only 2.4 Mb) which provides a superior solution for developing and deploying Rails application. The main reasons for using GlassFish instead of WEBrick/Mongrel/LightTPD are:

• Identical development and deployment environments
• Handles multiple requests by maintaining JRuby runtimes and database connection pools
• Ability to redploy an application without restarting container
• In-built Clustering, Load Balancing, and High Availability support
• Allows to leverage investment in a Java EE infrastructure and cohosting Ruby-on-Rails and Java EE applications

All the above mentioned reasons, and much more, are explained in detail in Rails powered by the GlassFish Application Server.

The gem installation is extremely simple as shown below:

~/testbed/jruby-1.1 >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 93 gems from http://gems.rubyforge.org ............................................................................................. complete Successfully installed glassfish-0.1.2-universal-java 1 gem installed

After the gem is installed, get started by developing a simple scaffold application or Mephisto.

If you are attending JavaOne 2008, then LAB 8400 will show how to develop and deploy Rails applications using NetBeans and deploy them on GlassFish. LAB 4520 will teach you more about the modular and pluggable GlassFish v3 architecture.

GlassFish JRuby wiki or JRuby wiki gives you all the latest information about JRuby-on-Rails and GlassFish.

BitNami's JRubyStack = JRuby + Rails + GlassFish Gem + MySQL all bundled together

BitNami provides easy-to-use, integrated and multiplatform install bundles for different open source apps. They released JRubyStack last week which includes JRuby 1.1 RC2, Rails 2.0.2, GlassFish v3 Gem 0.1.1, MySQL 5.0.45 and some other miscellaneous components. The components mentioned here are all you need to get started with hosting your JRuby-on-Rails applications on GlassFish. Refer to release notes for more details.

The steps below walks you through installation of JRubyStack. It shows how this stack provides an integrated and ready-to-use bundle for hosting your applications on GlassFish:

1. Install JRubyStack
   1. Download JRubyStack from here. Click on the installer to see:
      
      
       
   2. Clicking on "Next >" brings the following screen:
      
      
      
      Even though it shows "JRuby on Rails" component but it includes everything, including GlassFish v3 Gem & MySQL server, in it.
   3. Further in the installation process, change the database user name from default "jrubystack" to "root". Take all other defaults through out the installation process.
   4. After the installation is completed, the following program menu is added
      
      
       
2. After the bundle is installed, it's ready to use - MySQL server is started, a default application is created in "C:\Users\Arun Gupta\BitNami JRubyStack projects\jrubystack" and hosted using GlassFish v3 gem at "http://localhost:3000". Here is the output shown in the console window started by JRubyStack:

TOTD #28: Getting Started with Rails 2.0 Scaffold

Rails 2.0 changes the way Scaffold works. This blog walks you through the steps to create a simple CRUD application using Scaffold in Rails 2.0.

1. Download & Install JRuby 1.1 RC2.
2. Install Rails using the following command:
   
   jruby -S gem install rails
3. Create a new Rails app using the following command:
   
   cd samples; mkdir rails; cd rails
jruby -S rails books -d mysql
4. Start MySQL server in a different shell using the following command:
   
   sudo /usr/local/mysql/bin/mysqld_safe --console
5. Creat the database using the following command:
   
   cd books
jruby -S rake db:create

   This creates the database defined by RAILS_ENV (Development is default). Here are some other new database-related commands:
   
   

   db:create:all	Create all the databases (_Development, _Test, _Production)
   db:drop	Drops your database
   db:reset	Drop and Re-create your database, including migrations

6. Generate a scaffold using the following command:
   
jruby script/generate scaffold book title:string author:string isbn:string description:text
   
   The output of the command looks like:
   
      exists  app/models/
      exists  app/controllers/
      exists  app/helpers/
      create  app/views/books
      exists  app/views/layouts/
      exists  test/functional/
      exists  test/unit/
      create  app/views/books/index.html.erb
      create  app/views/books/show.html.erb
      create  app/views/books/new.html.erb
      create  app/views/books/edit.html.erb
      create  app/views/layouts/books.html.erb
      create  public/stylesheets/scaffold.css
  dependency  model
      exists    app/models/
      exists    test/unit/
      exists    test/fixtures/
      create    app/models/book.rb
      create    test/unit/book_test.rb
      create    test/fixtures/books.yml
      create    db/migrate
