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.

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

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
      create    db/migrate/001_create_books.rb
      create  app/controllers/books_controller.rb
      create  test/functional/books_controller_test.rb
      create  app/helpers/books_helper.rb
      route  map.resources :books
   
   There is no need to create the model explicitly as was the case in previous version of Rails. This creates the "db/migrate/001_create_books.rb" migration which looks like:
   
   class CreateBooks < ActiveRecord::Migration
  def self.up
    create_table :books do |t|
      t.string :title
      t.string :author
      t.string :isbn
      t.text :description

      t.timestamps
    end
  end

  def self.down
    drop_table :books
  end
end
7. Create the database tables using the following command:
   
   jruby -S rake db:migrate
8. Deploy the application on WEBrick using the following command:
   
jruby script/server
   
   The application is now available at "http://localhost:3000/books" and looks like:
   
   
   
9. Click on "New book" to see a page as shown below (with values entered):
   
   
   Click on Create button. After 2 entries have been entered, it looks like as shown below:

GlassFish v3 gem on JRuby 1.1 RC2

JRuby 1.1 RC2 was released earlier today an GlassFish v3 gem works like a charm on it :)

Read the complete announcement here. The key features of RC2 are:

1. 260 issues resolved
2. Large IO refactoring
3. Less memory than previous release
1. Control total number of JIT'd methods
2. Support a JIT cache between runtimes to return permgen
3. 50-70% reduction in generated methods

1. Download JRuby 1.1 RC2. 
2. Install Rails and create a simple Rails application as described in TOTD #24.
3. Install GlassFish v3 gem using the command as shown below:
   
   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-0.1.1-universal-java
1 gem installed
4. And now the simple application can be easily deployed on GlassFish gem as:
   
   jruby -S glassfish_rails hello
   
   Notice this command needs to be given from the parent directory of the application. The Applcation environment is as shown below:
   
   
   
   and the application output looks like exactly as expected:

GlassFish v3 Gem - 0.1.1 available

Pramod released an updated version 0.1.1 of the JRuby GlassFish v3 gem.

What's New ? - Mainly alignment with Rails convention

1. The name of the gem is changed from "GlassFish" to "glassfish".
2. The default port number is 3000.
3. Applications are deployed at root context ("/"). So the default application is now deployed "http://localhost:3000/home/index" instead of "http://localhost:8080/temp/home/index".

1. The number of concurrent requests can now be set using a command-line argument (instead of "-J-Djruby.runtime"). So 2 Rails instances can be created using the following command:
   
   jruby -S glassfish_rails temp -n 2
2. Rails instances are created in parallel to improve the startup time of the gem.

TOTD #18: How to Build The GlassFish v3 Gem for JRuby ?

Jerome posted the instructions to build GlassFish v3 Gem for JRuby - very simple and easy. A binary version of Gem is available here.

1. Software pre-requisite
   1. Subversion client (for example Tigris)
   2. Maven 2.0.x
   3. JRuby 1.0.x (I used JRuby 1.0.2 and lets say installed in JRUBY_HOME).  Make sure JRUBY_HOME/bin is in your path.
2. Build the Gem

   1. As explained in Jerome's entry, you can check out complete GlassFish v3 workspace or just the Gem code. Here is how you'll check out only the Gem code on a Windows machine using Tigris Subversion client:
      
      
      
      And after the check out is complete, you'll see:
      
      

   2. Build the gem by giving the command:
      
      mvn install
      
      And success is achieved by seeing the following in the console:
      
      [INFO] (in C:/workspaces/glassfish/gem/target/dependency/glassfish)
[WARNING] mkdir -p pkg

The Gem is available in target\dependency\glassfish\pkg directory.
3. Install the Gem
   1. Change to the directory where the Gem is available
      
      cd target\dependency\glassfish\pkg
   2. Install the Gem as:
      
      C:\testbed\ruby\jruby-1.0.2\bin\jruby -S gem install GlassFish-10.0.0-java.gem
Successfully installed GlassFish, version 10.0.0

And use it!

Please leave suggestions on other TOTD that you'd like to see. A complete archive is available here.

Mephisto with GlassFish v3 Gem

In an Earlier Post, I described how Mephisto (a popular web publishing system based on Ruby on Rails) can be deployed on GlassFish V3. Both JRuby and GlassFish has matured since then and this post will provide the updated instructions to deploy Mephisto using GlassFish v3 Gem.

Here are the exact steps:

1. Install and Configure JRuby 1.0.2. The GlassFish v3 Gem does not work on Windows (JRUBY-1549) with JRuby 1.0.2 and you need to use the JRuby trunk workaround.
   1. Download and Unzip JRuby1.0.2 (lets say JRUBY_HOME).
   2. Include 'JRUBY_HOME/bin' in your environment PATH.
   3. Install Rails (with all dependencies) in JRuby installation by giving the command:
      
      C:\workspaces\jruby-trunk>bin\jruby -S gem install rails --include-dependencies --no-ri --no-rdoc
Bulk updating Gem source index for: http://gems.rubyforge.org
Successfully installed rails-1.2.5
Successfully installed activesupport-1.4.4
Successfully installed activerecord-1.15.5
Successfully installed actionpack-1.13.5
Successfully installed actionmailer-1.3.5
Successfully installed actionwebservice-1.2.5
   4. Install ActiveRecord-JDBC as shown below:
      
      C:\workspaces\jruby-trunk>bin\jruby -S gem install activerecord-jdbc -y --no-rdoc --no-ri
Need to update 1 gems from http://gems.rubyforge.org
.
complete
Successfully installed ActiveRecord-JDBC-0.5
2. Download and Install GlassFish V3 Gem.
3. Install and Configure Database
   1. Download and install MySQL Community Server 5.0 (lets say MYSQL_HOME).
   2. Start MySQL database by giving the command 'mysqld-nt --user root --console' in MYSQL_HOME/bin directory on Windows or './bin/mysqld_safe' from MYSQL_HOME directory on Unix flavors.
   3. In a different shell window, create a database and grant privileges by giving the following commands:
       
      C:\Program Files\MySQL\MySQL Server 5.0\bin>mysqladmin --u root create mephisto_development

C:\Program Files\MySQL\MySQL Server 5.0\bin>mysql -u root
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 2
Server version: 5.0.45-community-nt MySQL Community Edition (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> grant all on mephisto_development.* to arun@localhost identified by 'noway';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> quit;
Bye
4. Install and Configure Mephisto
   1. Download and Unzip Mephisto 0.7.3.
   2. Install Mephisto as described here. The two steps are summarized below for convenience:
      1. Copy 'MEPHISTO_HOME/config/database.example.yml' to 'MEPHISTO_HOME/config/database.yml'. There is no need to specify the JDBC adapter ActiveRecord 0.5 onwards and that allows to use the default database configuration file.
      2. Bootstrap the development database using the command:
         
         C:\testbed\mephisto-0.7.3>jruby -S rake db:bootstrap -J-DRAILS_ENV=development

         and that shows the following output in the console:
         
(in C:/testbed/mephisto-0.7.3)
mkdir -p C:/testbed/mephisto-0.7.3/config/../log
-- create_table("assets", {:force=>true})
-> 0.3330s
-- create_table("assigned_sections", {:force=>true})
-> 0.2000s
-- create_table("cached_pages", {:force=>true})
-> 0.2980s
-- create_table("content_versions", {:force=>true})
-> 0.2130s
-- create_table("contents", {:force=>true})
-> 0.2190s
-- create_table("events", {:force=>true})
-> 0.2680s
-- create_table("memberships", {:force=>true})
-> 0.1890s
-- create_table("sections", {:force=>true})
-> 0.1500s
-- create_table("sessions", {:force=>true})
-> 0.1200s
-- add_index("sessions", ["session_id"], {:name=>"sessions_session_id_index"})
-> 0.3220s
-- create_table("sites", {:force=>true})
-> 1.1240s
-- add_index("sites", ["host"], {:name=>"index_sites_on_host"})
-> 0.3490s
-- create_table("taggings", {:force=>true})
-> 0.1950s
-- create_table("tags", {:force=>true})
-> 0.1840s
-- create_table("users", {:force=>true})
-> 0.2750s
-- initialize_schema_information()
-> 0.2740s
-- columns("schema_info")
-> 0.0170s
copied default theme to C:/testbed/mephisto-0.7.3/config/../themes/site-1...

================================================================================

Thank you for trying out Mephisto 0.7.3: Noh-Varr Edition!

Now you can start the application with script/server, visit
http://mydomain.com/admin, and log in with admin / test.

For help, visit the following:
Official Mephisto Site - http://mephistoblog.com
The Mephisto Community Wiki - http://mephisto.stikipad.com/
The Mephisto Google Group - http://groups.google.com/group/MephistoBlog
5. Deploy Mephisto on GlassFish v3 Gem as shown below:
   
   C:\testbed>\workspaces\jruby-trunk\bin\jruby -S glassfish_rails mephisto-0.7.3

And that shows the following output in the console:

Nov 14, 2007 6:37:51 PM com.sun.enterprise.v3.services.impl.GrizzlyAdapter postConstruct
INFO: Listening on port 8080
Nov 14, 2007 6:37:51 PM com.sun.enterprise.v3.services.impl.DeploymentService postConstruct

6. Mephisto is now deployed at http://localhost:8080/mephisto-0.7.3
   
   
   
   and shows the following output in GlassFish console:

JRuby 1.0.2 released - Improved Windows experience and Rails 1.2.5 support

JRuby 1.0.2 was released last week.

A total of 99 issues were fixed but I'm particularly excited about JRUBY-1347, JRUBY-1350, JRUBY-1401 and JRUBY-1410. These are some issues that I faced (1347 here, 1350 here, 1401 here, 1410 here) on my primary development machine - Windows.

Here is the status report:

• On Windows only, the latest Rails gem (1.2.5) is now working with stable release of JRuby (1.0.2 as of today).

• On Windows only, GlassFish v3 gem does not work with JRuby 1.0.2 but works with the JRuby trunk (JRUBY-1549). The gem works correctly on Solaris and Mac.

• JRuby 1.0.2 bundles will be available on GlassFish Update Center soon.

Now the details.

Here is the command sequence for creating and hosting a trivial Hello World on WEBrick:

1. Install Rails
   
   C:\testbed\ruby\jruby-1.0.2>bin\jruby -S gem install rails --include-dependencies --no-ri --no-rdoc
Bulk updating Gem source index for: http://gems.rubyforge.org
Successfully installed rails-1.2.5
Successfully installed activesupport-1.4.4
Successfully installed activerecord-1.15.5
Successfully installed actionpack-1.13.5
Successfully installed actionmailer-1.3.5
Successfully installed actionwebservice-1.2.5

2. Create a template application
   
   C:\workarea\samples\rails>\testbed\ruby\jruby-1.0.2\bin\jruby -S rails hello
 create
create app/controllers
create app/helpers
create app/models

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. Add a controller
   
   C:\workarea\samples\rails>cd hello

C:\workarea\samples\rails\hello>\testbed\ruby\jruby-1.0.2\bin\jruby script\generate controller say hello
exists app/controllers/
exists app/helpers/
create app/views/say
exists test/functional/
create app/controllers/say_controller.rb
create test/functional/say_controller_test.rb
create app/helpers/say_helper.rb
create app/views/say/hello.rhtml

4. Edit Controller
   
   C:\workarea\samples\rails\hello>vim app\controllers\say_controller.rb

   Add  @hello_string = "Hello from 1.0.2" in hello helper. The updated file looks like:
   
   class SayController < ApplicationController

  def hello
    @hello_string = "Hello from 1.0.2"
  end
end

5. Edit View

   C:\workarea\samples\rails\hello>vim app\views\say\hello.rhtml

   and add <%= @hello_string %> as the last line. The updated file looks like:
   
   <h1>Say#hello</h1>
<p>Find me in app/views/say/hello.rhtml</p>
<%= @hello_string %>

6. Start WEBrick and view the page http://localhost:3000/say/hello in a browser window:
   
   C:\workarea\samples\rails\hello>\testbed\ruby\jruby-1.0.2\bin\jruby script\server
=> Booting WEBrick...
=> Rails application started on http://0.0.0.0:3000
=> Ctrl-C to shutdown server; call with --help for options

127.0.0.1 - - [07/Nov/2007:17:22:38 PST] "GET /say/hello HTTP/1.1" 200 81
- -> /say/hello

The GlassFish v3 Gem does not work with JRuby 1.0.2 (JRUBY-1549) on Windows. It works very well on Solaris and Mac. For Windows, you need to use the JRuby trunk (checkout and build):

After you've built the JRuby trunk, you can create a similar new application and run it on GlassFish v3 gem as:

1. Download and Install the gem
   
   C:\workspaces\jruby-trunk>bin\jruby -S gem install glassfish-gem-10.0-SNAPSHOT.gem
Successfully installed GlassFish, version 10.0.0

2. Start GlassFish v3 and view the page http://localhost:8080/hello/say/hello:
   
   C:\workarea\samples\rails>\workspaces\jruby-trunk\bin\jruby -S glassfish_rails hello

Announcing GlassFish Gem for Rails

Jerome has been working on GlassFish gem for Rails. Read the interesting discussion on dev@glassfish. This blog announces a technology preview of this gem and describes the steps to try it out.

1. Download GlassFish Gem from here.

2. If you already have JRuby on Rails configured, then skip this step. Otherwise you need to install JRuby on Rails.
   1. Download and Unzip JRuby 1.0.1 from here (lets say JRUBY_HOME).

   2. In JRUBY_HOME\bin directory, install Rails plugin using the following command:
      
      jruby -S gem install rails -y --no-rdoc --no-ri
      
      The output of the command looks like:
      
      Bulk updating Gem source index for: http://gems.rubyforge.org
Successfully installed rails-1.2.3
Successfully installed activesupport-1.4.2
Successfully installed activerecord-1.15.3
Successfully installed actionpack-1.13.3
Successfully installed actionmailer-1.3.3
Successfully installed actionwebservice-1.2.3

3. Some platform specific changes listed below are required due to bugs in JRuby 1.0.1.
   1. Only on Windows
      1. Edit "JRUBY_HOME\bin\_jrubyvars.bat" and replace
         
         for /r "%JRUBY_HOME%\lib" %%i in (*.jar) do @call "%~dp0_jrubysetcp" %%i
         
         with
         
         for %%i in ("%JRUBY_HOME%\lib"\*.jar) do @call "%~dp0_jrubysetcp" %%i
         
         This change is required because "/r" switch causes the entire tree of the directory to be parsed instead of just including the JARs in JRUBY_HOME/lib directory. More details here. This is filed as bug #1347.
      2. The value of CLASSPATH environment variable increases exponentially with each execution of the gem. Then you start seeing the following error in your command shell:
         
         The input line is too long.
:gotCP
was unexpected at this time.
         
         This is a filed as bug #1350. A workaround is to start a new shell when you start seeing the error.

   2. Only on Macintosh: "JRUBY_HOME\bin\glassfish_rails" script executable permissions need to be set explicitly. This is filed as bug #1348.

4. Install the GlassFish gem using the command:
   
   c:\Downloads>\jruby-1.0.1\bin\gem install glassfish-gem-10.0-SNAPSHOT.gem
   
   The output of the command looks like:
   
   Successfully installed GlassFish, version 10.0.0
   
   Notice, you need to invoke this command from the directory where the gem was downloaded.

5. Create a new rails app using the following command:
   
   %JRUBY_HOME%\bin\jruby -S rails hello
   
   The output of the command looks like:
   
   create
create app/controllers
create app/helpers
create app/models
create app/views/layouts
create config/environments
create components
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/mocks/development
create test/mocks/test
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 public/.htaccess
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/breakpointer
create script/console
create script/destroy
create script/generate
create script/performance/benchmarker
create script/performance/profiler
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/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

6. Start GlassFish for this newly created app using the following command:
   
   %JRUBY_HOME%\bin\jruby -S glassfish_rails hello

   You need to invoke the command from outside the application directory instead of the natural way (script\server start). This will be fixed in the future builds. The output of the command looks like:
   
Sep 13, 2007 1:32:42 PM com.sun.enterprise.v3.services.impl.GrizzlyAdapter postConstruct
INFO: Listening on port 8080
Sep 13, 2007 1:32:42 PM com.sun.enterprise.v3.services.impl.DeploymentService postConstruct
INFO: Supported containers : jruby,web,php,phobos
Sep 13, 2007 1:32:43 PM com.sun.grizzly.standalone.StaticResourcesAdapter <init>
INFO: New Servicing page from: C:\workarea\samples\rails\hello\public
C:/jruby-1.0.1/lib/ruby/gems/1.8/gems/actionmailer-1.3.3/lib/action_mail
er.rb:49 warning: already initialized constant MAX_LINE_LEN
Sep 13, 2007 1:32:51 PM com.sun.enterprise.v3.server.AppServerStartup run
INFO: Glassfish v3 started in 8996 ms

7. Now you can view the default GlassFish web page at "http://localhost:8080".

This verifies the basic installation of the GlassFish gem. Lets add a simple controller to our application.

1. Add a controller to the application by changing to the directory "hello" and giving the command:
   
   jruby script\generate controller say hello

   The output of the command looks like:

   exists app/controllers/
exists app/helpers/
create app/views/say
exists test/functional/
create app/controllers/say_controller.rb
create test/functional/say_controller_test.rb
create app/helpers/say_helper.rb
create app/views/say/hello.rhtml

2. In hello\app\views\say directory, edit "hello.rhtml" such that it looks like:
   
   <h1>Say#hello</h1>
<p>Find me in app/views/say/hello.rhtml</p>
<%= @hello_string %>
3. In hello\app\controllers directory, edit "say_controller.rb" such that it looks like:

   class SayController < ApplicationController
  def hello
    @hello_string = "Hello from Controller!"
  end
end

4. The page is now accessible at "http://localhost:8080/hello/say/hello".

This is hosted using GlassFish. Of course, the same application can be deployed on WEBrick by giving the command:

jruby script\server webrick start

Try your applications on GlasFish gem and let us know by leaving a comment on this blog or sending an email to users@glassfish or posting to GlassFish forum.

You can also download GlassFish V3 standalone builds from here. The instructions to deploy a Rails application on GlassFish V3 are available here and on V2 here.
