TOTD #44: JDBC Connection Pooling for Rails on GlassFish v3

TOTD #9 explained how to configure JDBC connection pooling for Rails application deployed on GlassFish v2. There are several benefits of using using the JDBC connection pools:

• No need to create a new database connection for each Rails instance.
• No need to specify your password in database.yml or create a hack to hide it.
• No garbage collection of connection after each use.

1. Lets create a simple scaffold
   
   

   ~/samples/jruby >~/tools/jruby-1.1.3/bin/jruby -S rails jndi_rails2 -d mysql ~/samples/jruby/jndi_rails2 >~/tools/jruby-1.1.3/bin/jruby script/generate scaffold runner miles:float minutes:integer ~/samples/jruby/jndi_rails2 >~/tools/jruby-1.1.3/bin/jruby -S rake db:create ~/samples/jruby/jndi_rails2 >~/tools/jruby-1.1.3/bin/jruby -S rake db:migrate

2. Install MySQL ActiveRecord JDBC adapter
   
   

   ~/samples/jruby/jndi_rails2 >~/tools/jruby-1.1.3/bin/jruby -S gem install activerecord-jdbcmysql-adapter

3. Copy MySQL Connector/J jar to JAVA_HOME/lib/ext
   
   

   ~/samples/jruby/jndi_rails2 >sudo cp ~/tools/mysql-connector-java-5.1.6/mysql-connector-java-5.1.6-bin.jar /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home/lib/ext

4. Start GlassFish v3 server as ...
   
   

   ~/tools/glassfish/v3/b23/glassfishv3-prelude/glassfish >java -Xmx512m -DJRUBY_HOME=/Users/arungupta/tools/jruby-1.1.3 -jar modules/glassfish-10.0-SNAPSHOT.jar

5. Setup JDBC connection pool
1. Create JDBC connection pool
   
   

   ~/samples/jruby/jndi_rails2 >~/tools/glassfish/v3/b23/glassfishv3-prelude/glassfish/bin/asadmin create-jdbc-connection-pool --datasourceclassname com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource --restype javax.sql.DataSource --property "User=duke:Password=duke:URL=jdbc\:mysql\://localhost/jndi_rails2_production" jdbc/jndi_rails2_pool

2. Create JDBC resource
   
   

   ~/samples/jruby/jndi_rails2 >~/tools/glassfish/v3/b23/glassfishv3-prelude/glassfish/bin/asadmin create-jdbc-resource --connectionpoolid jdbc/jndi_rails2_pool jdbc/jndi_rails2

3. Ping JDBC pool
   
   

   ~/samples/jruby >~/tools/glassfish/v3/b23/glassfishv3-prelude/glassfish/bin/asadmin ping-connection-pool jdbc/jndi_rails2_pool

6. Change the development database in config/database.yml to:
   
   

   development:   adapter: jdbc   jndi: jdbc/jndi_rails2   driver: com.mysql.jdbc.Driver

7. Run your app as
   
   

   ~/samples/jruby >~/tools/glassfish/v3/b22/glassfishv3-prelude/glassfish/bin/asadmin deploy jndi_rails2

Typo on GlassFish v3 - Ruby-on-Rails Blogging Engine

Typo is an open-source Blogging Engine written using Ruby-on-Rails framework. It provides a lean engine that makes blogging easy. It's main attribtues are ease of use, usability, beauty and excellent support of web standards.

1. Typo can be installed as Gem or from Sources. Installing as gem gives the following error:
   
   

   JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Building native extensions.  This could take a while... /Users/arungupta/tools/rails20/jruby-1.1.3/lib/ruby/1.8/mkmf.rb:7: JRuby does not support native extensions. Check wiki.jruby.org for alternatives. (NotImplementedError)         from /Users/arungupta/tools/rails20/jruby-1.1.3/lib/ruby/1.8/mkmf.rb:1:in `require'         from extconf.rb:1 ERROR:  Error installing typo:         ERROR: Failed to build gem native extension. /Users/arungupta/tools/rails20/jruby-1.1.3/bin/jruby extconf.rb install typo Gem files will remain installed in /Users/arungupta/tools/rails20/jruby-1.1.3/lib/ruby/gems/1.8/gems/mysql-2.7 for inspection. Results logged to /Users/arungupta/tools/rails20/jruby-1.1.3/lib/ruby/gems/1.8/gems/mysql-2.7/gem_make.out

   
   This is discussed here. In the meanwhile, download and unzip Typo 5.1.2 as:
   
   

   ~/samples/jruby >unzip ~/Downloads/typo-5.1.2.zip Archive:  /Users/arungupta/Downloads/typo-5.1.2.zip    creating: typo-5.1.2/    creating: typo-5.1.2/app/    creating: typo-5.1.2/app/apis/    . . .   inflating: typo-5.1.2/vendor/uuidtools/lib/uuidtools.rb    inflating: typo-5.1.2/vendor/uuidtools/rakefile    inflating: typo-5.1.2/vendor/uuidtools/README

2. Create the database:
   
   

   ~/samples/jruby >sudo mysqladmin create typo_dev

   
   Typo 5.1.x works with Rails 2.0.x only and so migrate as shown below:
   
   

   ~/samples/jruby/typo-5.1.2 >~/tools/rails20/jruby-1.1.3/bin/jruby -S rake db:migrate (in /Users/arungupta/samples/jruby/typo-5.1.2) == 1 InitialSchema: migrating ================================================= -- create_table(:users)    -> 0.0377s -- create_table(:articles)    -> 0.0189s -- add_index(:articles, :permalink)    -> 0.0094s -- create_table(:categories)    -> 0.0069s  . . . == 69 AddModulesToProfile: migrating ========================================== -- add_column(:profiles, :modules, :text)    -> 0.0072s == 69 AddModulesToProfile: migrated (0.0454s) ================================= == 70 AddUsersToNonAdmins: migrating ========================================== == 70 AddUsersToNonAdmins: migrated (0.0488s) =================================


Typo 5.2 (scheduled in 3 days) will work with Rails 2.1.

3. Download GlassFish (nightly, promoted or build-your-own) and install by unzipping. I tried the nightly of 8/24 as:
   
   

   ~/tools/glassfish/v3/8-24 >unzip ~/Downloads/glassfish-snapshot-v3-prelude-08_24_2008.zip Archive:  /Users/arungupta/Downloads/glassfish-snapshot-v3-prelude-08_24_2008.zip    creating: glassfish/    creating: glassfish/docs/    creating: glassfish/docs/css/    creating: glassfish/docs/graphics/ . . .   inflating: glassfish/lib/templates/login.conf    inflating: glassfish/lib/templates/profile.properties    inflating: glassfish/lib/templates/server.policy

4. Start GlassFish as:
   
   

   ~/tools/glassfish/v3/8-24/glassfish >java -DJRUBY_HOME=/Users/arungupta/tools/rails20/jruby-1.1.3 -jar modules/glassfish-10.0-SNAPSHOT.jar Aug 26, 2008 5:56:10 PM com.sun.enterprise.glassfish.bootstrap.ASMain main INFO: Launching GlassFish on Apache Felix OSGi platform Welcome to Felix. ================= Aug 26, 2008 5:56:11 PM HK2Main start INFO: contextRootDir = /Users/arungupta/tools/glassfish/v3/8-24/glassfish/modules Aug 26, 2008 5:56:11 PM OSGiFactoryImpl initialize . . .

5. And deploy Typo as:
   
   

   ~/samples/jruby >~/tools/glassfish/v3/8-24/glassfish/bin/asadmin deploy typo-5.1.2 Command deploy executed successfully.

JRuby 1.1.3 released - Getting Started with GlassFish

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

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:

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. ================= . . .

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:

NetBeans 6.5 M1: GlassFish v3 + Rails

NetBeans IDE 6.5 Milestone 1 is now available. The New and Noteworthy feature list certainly makes it worthy for the install - comprehensive PHP support (Editor Screencast and PHP Learning Trail), JavaScript Debugger, Groovy Editor, Grails support and Numerous improvements in other areas are some of them.

Let's get started!

1. Download NetBeans 6.5 M1. Installation is pretty straight-forward and I customized it with the following options:
   
   
   
   After a simple installation process, check the "About" box as:
   
   
   
   
   
2. GlassFish v3 plug-in and TP2 is baked into the main release and so it is pre-configured for you. No need to install the additional plugin.
   
   This blog walks you through creating a simple Rails app and shows the nice improvements along the way.
   
3. Let's create a simple Rails app:
   
   
   
   Notice, GlassFish v3 is chosen as the default Server.
4. Specify the database connection as:
   
   
   
   and click on "Finish". NetBeans is bundled with JRuby 1.1.2 and Rails 2.1.0.
   
5. Start MySQL as "sudo mysqld_safe --user root".
6. Running Rake commands from within is more natural now. Right-click on the project and select "Run/Debug Rake Task ..."
   
   
   
   The dialog shows all the Rails rake tasks available. Typing the Rake command prunes the list matching
   the pattern and shows:
   
   
   
   Type "db:create" and select "Run".
   
7. Create a new Scaffold by right-clicking on "Project" and selecting "Generate..." and entering the value as shown:
   
   
   
   and clicking on "OK".
   
8. Migrate the database by invoking Rake command as shown:
   
   
   
   and selecting "Run".
   
9. Right-select the project and select "Run" as shown:
   
   
   
   The default App Server page at "http://localhost:8080" is shown. This will be updated to "http://localhost:8080/RailsApplication19" which is the default Rails page for the final release.
   
10. After adding couple of entries the final output looks like:

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.

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/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:

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:

JRuby-on-Rails and MySQL on GlassFish on OpenSolaris in Virtual Box VM

My primary development machine is Mac OS Leopard on Intel Core 2 Duo (read osxtips). But the beauty of virtualization is that I can run multiple Operating Systems on a single powerful machine. And what better virtualization product than Virtual Box. And  Open Solaris has crossed leaps and boundaries making installation and getting started extremely simple :)

So here is an application stack that I tried:

Rails 2.1 + My SQL 5.0.51a JRuby 1.1.2 GlassFish v3 TP2 OpenSolaris 2008.05 Virtual Box 1.6.2 Mac OSX Leopard Intel 2.4 G Hz Core 2 Duo

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

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:

   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:

Tic Tac Toe using Rails and Grails on GlassFish v3

GlassFish v3 is a modular (OSGi compliant), embeddable (runs in-VM) and extensible (hosts non-Java applications) Application Server. The "extensible" part was demonstrated during JavaOne 2008 by deploying Rails, Grails and Django sample application on GlassFish v3 Technology Preview 2. This blog announces the availability of Rails, Grails and (of course!) Java EE version of the demo code.

The sample application is a simple multi-player game that can be played on Internet and deployed on GlassFish. One of the simplest multi-player game is Tic-Tac-Toe. The complete instructions to checkout, build, deploy and run the sample are available here. The demo can certainly be improved by using the best practices from Rails and Grails and I'll work on them in next few days.

The demo is played in 2 different browser windows (tested on Firefox, Safari & IE). The clicks in the grid on one browser are displayed on the other browser (propagated using GlassFish Comet) and row and column winners are shown.

• GlassFish v3 supports deployment of Rails and Grails applications, in addition to traditional Java EE apps.
• GlassFish v3 has a completely modular architecture as evident by the pluggability of JRuby/Rails.
• Features of the underlying GlassFish runtime can be accessed.
• Any click in the grid is pushed to the endpoint and then propagated to all the clients using GlassFish Comet. So effectively, now you can build Comet-enabled applications using Rails and Grails.
• Rails application is deployed as a composite application where Serlvet is bundled with the application and accessed from the View.

Redmine on GlassFish - Ruby-on-Rails Project Management Application

Redmine is a flexible project management web application written using Ruby on Rails framework. The feature list is pretty comprehensive from the usual suspects like multiple projects, role-based control, forums/wikis/SCM for each project to enterprise level features such as LDAP-authentication and multiple languages. It is cross-platform and cross-database and deploys very nicely on GlassFish v3.

GlassFish v3 modularity and extensibility allows Rails applications to be deployed without any modification (no WARing). This blog explains the steps on how to deploy Redmine on GlassFish and shows some screenshots later. More documentation is available in Redmine Guide.

1. Check out the most stable release of Redmine by giving the command:
   
   

   ~/testbed/redmine >svn co http://redmine.rubyforge.org/svn/branches/0.7-stable redmine-0.7

2. Configure the database
1. Start your MySQL server 
   
   

   ~/testbed/redmine >sudo mysqld_safe --user root Starting mysqld daemon with databases from /usr/local/mysql/data

2. Create the database as:
   
   

   ~/testbed/redmine/redmine-0.7 >../jruby-1.1.1/bin/jruby -S rake db:create (in /Users/arungupta/testbed/redmine/redmine-0.7)

3. Migrate the database as:
   
   

   ~/testbed/redmine/redmine-0.7 >../jruby-1.1.1/bin/jruby -S rake db:migrate (in /Users/arungupta/testbed/redmine/redmine-0.7) == 1 Setup: migrating ========================================================= -- create_table("attachments", {:force=>true})    -> 0.2840s -- create_table("auth_sources", {:force=>true})    -> 0.0540s -- create_table("custom_fields", {:force=>true})    -> 0.0430s -- create_table("custom_fields_projects", {:id=>false, :force=>true})    -> 0.0080s -- create_table("custom_fields_trackers", {:id=>false, :force=>true})    -> 0.0500s . . . == 90 ChangeVersionsNameLimit: migrating ====================================== -- change_column(:versions, :name, :string, {:limit=>nil})    -> 0.0220s == 90 ChangeVersionsNameLimit: migrated (0.0220s) ============================= == 91 ChangeChangesetsRevisionToString: migrating ============================= -- change_column(:changesets, :revision, :string, {:null=>false})    -> 0.0210s == 91 ChangeChangesetsRevisionToString: migrated (0.0230s) ==================== == 92 ChangeChangesFromRevisionToString: migrating ============================ -- change_column(:changes, :from_revision, :string)    -> 0.0130s == 92 ChangeChangesFromRevisionToString: migrated (0.0150s) ===================

3. Download, Install and Configure GlassFish v3
1. Download GlassFish v3 from here.
2. Unzip the downloaded bundle.
3. Add the following fragment as the last line in "glassfishv3-tp2/glassfish/config/asenv.conf" file:
   
   

   JRUBY_HOME="/Users/arungupta/testbed/redmine/jruby-1.1.1"

4. Deploy Redmine as:
   
   

   ~/testbed/redmine >./glassfishv3-tp2/glassfish/bin/asadmin deploy redmine-0.7 Command deploy executed successfully.

   
   ... and the GlassFish console shows:
   
   

   May 21, 2008 4:58:30 PM com.sun.enterprise.rails.RailsDeployer registerAdapter INFO: Loading application redmine-0.7 at /redmine-0.7 May 21, 2008 4:58:30 PM  INFO: Starting Rails instances May 21, 2008 4:58:37 PM  SEVERE: JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL May 21, 2008 4:58:42 PM com.sun.grizzly.jruby.RubyObjectPool$1 run INFO: Rails instance instantiation took : 11979ms May 21, 2008 4:58:42 PM com.sun.enterprise.v3.deployment.DeployCommand execute INFO: Deployment of redmine-0.7 done is 12091 ms

Benefit of using JRuby-on-Rails: Using Java 2D power within Rails

One of the main advantages of using JRuby-on-Rails instead of Ruby-on-Rails is to harness the power of Java libraries available in the Java platform. The Java 2D API is a set of classes for advanced 2D graphics and imaging, and provides extensive support for image compositing and alpha channel images, a set of classes to provide accurate color space definition and conversion, and a rich set of display-oriented imaging operators.

Jennifer published a new blog showing image-filtering effect (negative, grayscale, brigthen, sharpen). Read the complete entry.

A more comprehensive tutorial for JRuby-on-Rails on GlassFish v3 TP2 (also Jennifer's work) is available here.

TOTD #32: Rails Deployment on GlassFish v3 from NetBeans IDE

Rails powered by the GlassFish Application Server explains all the benefits of using GlassFish for developing and deploying your Rails applications. If you are using NetBeans 6.1 builds then you can deploy your Rails application directly on GlassFish v3 from within NetBeans IDE. No longer you need to have different development and deployment options.

This blog explains how to install a bleeding-edge GlassFish v3 plugin and use it to deploy your Rails app natively on GlassFish (no WAR or anything :). Let's get started! Note, this plugin is bleeding edge and will soon be released on the Beta Update Center.

1. Install "GlassFish v3 TP2" plugin in NetBeans 6.1
1. In NetBeans 6.1 IDE, go to "Tools", "Plugins" and click on "Settings". The following window is shown:
   
   
   
2. Click on "Add" and specify the URL of Bleeding Edge Update Center values as shown (copy from "http://deadlock.netbeans.org/hudson/job/javadoc-nbms/lastSuccessfulBuild/artifact/nbbuild/nbms/updates.xml.gz"):
   
   
   
   Click on "OK". The updated "Plugins" window looks like:
   
   
   
   
   Notice "Available Plugins" has changed from 58 to 140 as many more bleeding edge plugins are now available.
3. Click on "Available Plugins" and search for "GlassFish" in the top-right corner text box as shown below:
   
   
   
4. Select "GlassFish V3 JRuby Integration" and "GlassFish V3 JavaEE Integration" plugin and click on "Install" as shown below:
   
   
   
   Follow the instructions to install the plugin. The IDE needs to restart for successful plugin installation.
5. In the restarted IDE,  go to "Services" tab, right-click on "Servers" and select "Add Server...". Select "GlassFish v3 TP2" as shown below:
   
   
   
6. Select "Next >", accept the license agreement and click on "Download V3 Now..."
   
   
   
   Click on "Download V3 Now...". This downloads the latest GlassFish v3 TP2 build and installs in "/Users/arungupta/GlassFish_V3_TP2" directory. This is only an interim build, final TP2 build will be available soon! The following screen is shown once GlassFish v3 is installed:
   
   
   
   Click on "Finish". In 58 seconds, you downloaded and installed the entire GlassFish v3 app server, cool isn't it!
2. Create a Rails app and deploy on GlassFish V3
1. In NetBeans IDE, in the "Projects" tab, right-click and select "New Project...". Select "Ruby" in "Categories" and "Ruby on Rails Applications" in "Projects" as shown:
   
   
   
   Click on "Next".
2. Now comes the cool part. Enter the application name and select the recently installed GlassFish v3 as shown:
   
   
   
   This is a brand new feature in the "GlassFish v3 TP2" plugin available only on "Bleeding Edge" Update Center. It'll soon replace the default GlassFish v3 plugin from the Beta Update Center.
   
   Click on "Finish" to take all other defaults.
3. On the newly created project, right-click and select "Run" as shown:
   
   
4. The default browser page "http://localhost:8080/" shows up. Change the URL to "http://localhost:8080/HelloRails" and the following page shows up:

Rails and Java EE integration - Native Rails on GlassFish v3

The last part of this tri-series blog (Part 1, Part 2) will show how a Rails application can be deployed on GlassFish - without the need of Goldspike, Warbler or any other gem or plugin. Yes, that's a native Rails app deployment on GlassFish v3.

GlassFish v3 is next version of GlassFish v2 and the focus is modularization, enablement of non-Java EE containers and modularity - download b09.

Rails powered by GlassFish provides all the details on why GlassFish provides an industry-grade and functionally-rich Application Server.

Now detailed steps:

1. Using JRuby 1.1 (installed with Rails), create a Rails app "railsee3" as:
   
   

   ~/testbed/jruby-1.1/samples/rails >../../bin/jruby -S rails railsee3       create        create  app/controllers       create  app/helpers       create  app/models       . . .       create  log/production.log       create  log/development.log       create  log/test.log

2. Add Servlet descriptors
1. Create a new directory "WEB-INF", and a new file "web.xml" in that directory using the following contents:
   
   

   <!DOCTYPE web-app PUBLIC   "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"   "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app>         <servlet>                 <servlet-name>HelloServlet</servlet-name>                 <servlet-class>server.HelloServlet</servlet-class>         </servlet>         <servlet-mapping>                 <servlet-name>HelloServlet</servlet-name>                 <url-pattern>/hello</url-pattern>         </servlet-mapping> </web-app>

2. Create a new file "sun-web.xml" in "WEB-INF" using the following contents:
   
   

   <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE sun-web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Application Server 9.0 Servlet 2.5//EN" "http://www.sun.com/software /appserver/dtds/sun-web-app_2_5-0.dtd"> <sun-web-app error-url="">   <context-root>/servlet</context-root>   <class-loader delegate="true"/> </sun-web-app>

3. Create a new directory "WEB-INF/lib".
3. Create and Copy Servlet
1. Create a Java library with Servlet code as explained in bullet #5 here.
2. Copy "HelloServlet.jar" from "dist" directory of NetBeans project to "WEB-INF/lib" directory.
4. Configure JRuby-on-Rails in GlassFish - Edit "config/asenv.conf" in GlassFish directory and specify JRUBY_HOME as the last line:
   
   

   JRUBY_HOME="/Users/arungupta/testbed/jruby-1.1"

   
   
5. Deploy the Rails application as:



~/testbed/jruby-1.1/samples/rails >~/testbed/glassfish/v3/p2b9/glassfish/bin/asadmin deploy --force=true railsee3 railsee3 deployed successfully Command deploy executed successfully.

6. The bundled Servlet is now accessible at "http://localhost:8080/servlet/hello". The default browser output looks like:
   
   
   
   And passing a parameter to the URL as "http://localhost:8080/railsee3/hello?name=Arun" shows the output as:
   
   
   

7. Create a new Controller and View as
   
   

   ~/testbed/jruby-1.1/samples/rails/railsee3 >../../../bin/jruby script/generate controller home index JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL       exists  app/controllers/       exists  app/helpers/       create  app/views/home       exists  test/functional/       create  app/controllers/home_controller.rb       create  test/functional/home_controller_test.rb       create  app/helpers/home_helper.rb       create  app/views/home/index.html.erb

8. Change the generated controller in "app/controllers/home_controller.rb" to:
   
   

   class HomeController < ApplicationController include Java   def index         url = java.net.URL.new("http://localhost:8080/servlet/hello");         conn = url.open_connection;         reader = java.io.BufferedReader.new(java.io.InputStreamReader.new(conn.get_input_stream));         @servlet_output = "";         input_line = reader.read_line;         while input_line != nil                 @servlet_output << input_line;                 input_line = reader.read_line;         end         reader.close;   end end

9. Change the generated view in "app/views/home/index.rhtml.erb" to:
   
   

   <h1>Home#index</h1> <p>Find me in app/views/home/index.html.erb</p> <%= @servlet_output %>

10. Re-deploy the Rails application as shown in bullet # 5 above and "http://localhost:8080/railsee3/home/index" shows the output as shown:
    
    

• Part 1- WAR-based deployment on GlassFish v2 UR1 using Goldspike
• Part 2 - WAR-based deployment on GlassFish v2 UR1 using Warbler
• Part 3 - Native deployment on GlassFish v3 without any additional gems or plugins
