1400 registrations, 112 sessions, free pizza, a barbecue on Saturday night, raffles and lot more – that is Silicon Valley Code Camp. Jitu, Jiandong, Jacob, and I presented on GlassFish at Silicon Valley Code Camp over the weekend. The event had higher attendance (close to 500) than last year and certainly is a great networking event for the local community.

The venue at Foothill College is literally in foot of the hills and the campus is beautiful. The barebecue reception in the evening was certainly a pleasant relief to the attendees who did not get a pizza slice at lunch

If you could not attend any of our sessions hen you can read through the slides for GlassFish: The Best Open Source Application Server and Rails powered by GlassFish. The demos shown in the talk are available at:

• Develop/Run/Debug Rails application using NetBeans and GlassFish
• Rapid Deployment Technology for Web application using NetBeans and GlassFish
• Tic Tac Toe using Rails and GlassFish
• Embeddable GlassFish in Action
• Deploying OSGi bundles in GlassFish

Feel free to send any comments to users@glassfish.dev.java.net.

GlassFish v3 Prelude is now available. It allows Rails applications to be deployed natively using JRuby and without the need of any WAR packaging or Servlet container. An integrated NetBeans tooling provides a comprehensive development and deployment platform for all your Rails applications. And you can even purchase enterprise support as well!

This screencast shows how you can create a simple Rails application using NetBeans IDE, deploy it directly on GlassFish v3 and then debug it.

Typo, Redmine, Substruct, and Mephisto are some of the applications I’ve tried deploying on GlassFish. Have you tried deploying your Rails app on GlassFish ?

File Rails/GlassFish related bugs here using “jruby” sub-component and ask your questions on webtier@glassfish.dev.java.net.

This blog shows how to get started with Edge Rails (2.2, almost there) using JRuby. The blog uses JRuby 1.1.5 and GlassFish v3 Prelude b28c to deploy a simple Rails app.

1. Download and unzip JRuby 1.1.5.
2. JRuby 1.1.5 comes with “rake 0.8.3″. However if you are using JRuby 1.1.4, then you need to update “rake” version to 0.8.3 as:
   

   ~/tools/jruby-1.1.4 >bin/jruby -S gem update rake JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Updating installed gems Updating rake Successfully installed rake-0.8.3 Gems updated: rake

3. Install Edge Rails as:
   

   ~/tools/jruby-1.1.5 >bin/jruby -S gem install rails -s http://gems.rubyonrails.org -v 2.2.0 JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Successfully installed activesupport-2.2.0 Successfully installed activerecord-2.2.0 Successfully installed actionpack-2.2.0 Successfully installed actionmailer-2.2.0 Successfully installed activeresource-2.2.0 Successfully installed rails-2.2.0 6 gems installed Installing ri documentation for activesupport-2.2.0… Installing ri documentation for activerecord-2.2.0… Installing ri documentation for actionpack-2.2.0… Installing ri documentation for actionmailer-2.2.0… Installing ri documentation for activeresource-2.2.0… Installing RDoc documentation for activesupport-2.2.0… Installing RDoc documentation for activerecord-2.2.0… Installing RDoc documentation for actionpack-2.2.0… Installing RDoc documentation for actionmailer-2.2.0… Installing RDoc documentation for activeresource-2.2.0…

4. Create a new app as:
   

   ~/samples/jruby/edge >~/tools/jruby-1.1.5/bin/jruby -S rails helloworld -d mysql JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL       create         create  app/controllers       create  app/helpers . . .       create  log/server.log       create  log/production.log       create  log/development.log       create  log/test.log

5. Edge Rails do not ship with any(?, atleast MySQL) pure-Ruby database drivers and throws the following error if a database related operation is performed:
   

   ~/samples/jruby/helloworld >~/tools/jruby-1.1.5/bin/jruby -S rake db:create (in /Users/arungupta/samples/jruby/helloworld) !!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql. rake aborted! no such file to load — mysql (See full trace by running task with –trace)

   I find it weird that a database-backed framework does not ship database drivers. Anyway, lets install MySQL JDBC ActiveRecord adapter as:

   ~/tools/jruby-1.1.5 >bin/jruby -S gem install activerecord-jdbcmysql-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-mysql-5.0.4 Successfully installed activerecord-jdbcmysql-adapter-0.8.2 3 gems installed Installing ri documentation for activerecord-jdbc-adapter-0.8.2… Installing ri documentation for jdbc-mysql-5.0.4… Installing ri documentation for activerecord-jdbcmysql-adapter-0.8.2… Installing RDoc documentation for activerecord-jdbc-adapter-0.8.2… Installing RDoc documentation for jdbc-mysql-5.0.4… Installing RDoc documentation for activerecord-jdbcmysql-adapter-0.8.2…

   More details on configuring this adapter here.

6. Create a simple scaffold:
   

   ~/samples/jruby/edge/helloworld >~/tools/jruby-1.1.5/bin/jruby script/generate scaffold runner distance:float time: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&nb sp;   db/migrate       create    db/migrate/20081103190813_create_runners.rb ~/samples/jruby/edge/helloworld >~/tools/jruby-1.1.5/bin/jruby -S rake db:create (in /Users/arungupta/samples/jruby/edge/helloworld) ~/samples/jruby/edge/helloworld >~/tools/edge/jruby-1.1.5/bin/jruby -S rake db:migrate (in /Users/arungupta/samples/jruby/edge/helloworld) ==  CreateRunners: migrating ================================================== — create_table(:runners)    -> 0.0068s    -> 0 rows ==  CreateRunners: migrated (0.0077s) =========================================

   Some words here.

7. Change “config/database.yml” to use the JDBC adapter. Change:
   

   development:   adapter: mysql   encoding: utf8   database: helloworld_development   pool: 5   username: root   password:   socket: /tmp/mysql.sock

   to

   development:   adapter: jdbcmysql   encoding: utf8   database: helloworld_development   pool: 5   username: root   password:   socket: /tmp/mysql.sock

   The change is highlighted in bold letters.

8. Download GlassFish v3 Prelude 28c, unzip and start it as:
   

   ~/tools/glassfish/v3/28c/glassfishv3-prelude/glassfish >java -Xmx512m -DJRUBY_HOME=/Users/arungupta/tools/jruby-1.1.5/ -jar modules/glassfish.jar

9. Finally deploy the application as:
   

   ~/samples/jruby/edge >~/tools/glassfish/v3/28c/glassfishv3-prelude/glassfish/bin/asadmin deploy helloworld Command deploy executed successfully.

And now the scaffold is accessible at “http://localhost:8080/helloworld/runners”.

This application does not show any of the cool features (thread-safe, i18n, pooled datbase connections, …) coming up in Rails 2.2. But at least it clearly explains how to get started if you want to develop and run a Rails 2.2 application using JRuby.

Subsequent blogs will provide more information about performance advantages, multi threading, connection pooling and other benefits offered by GlassFish for Rails applications.

Wordle is pretty cool Applet (yeaaaah, still new ones are being developed that creates a word cloud from any RSS feed. I blog at blogs.sun.com and weblogs.java.net and most of the content is GlassFish-focused. Here are some wordles generated from my two feeds:

Once a wordle is generated, it can configured for different layout, font and color. Here are some more from “Miles to go” …

The corresponding tag cloud from the blog is given below:

The generated wordles do not seem to match the tag cloud (which is certainly more authoritative). For example, “NetBeans” is shown with much lesser intensity than “latitude” and “longitude”.

Anyway as evident from the wordles and tagcloud, GlassFish stands out very well – just like the product itself

And then couple of wordles from weblogs.java.net …

Here as well, This wordle is confusing because out of 517 blog entries, I’d guess 70-80% have GlassFish mentioned there. Even then “Mojarra” (JSF implementation from GlassFish community) is highlighted much more than GlassFish. Is that a bug ?

Wordles can be generated from random text or deli.icio.us tags as well. You can even see the word count and here is a sample:

But not sure how it generates them cause I’ve used the word “GlassFish” way more than 13 times just in subject!

Anyway, create your own and have fun!

Check out Alexis’s wordles as well.
