JRuby 1.2.0 RC1 is out for a while!

I typically run a series of tests to ensure that any publicly released version of JRuby works nicely with GlassFish. The main goal of running these tests is to discover any blocking bugs before users do. This particular set of tests are being run little late as RC1 was released on Feb 24th. But I’ll describe all the steps clearly in the next few blog entries so that you can try them out yourself.

JRuby team runs a whole slew of tests before releasing any bits. Similarly we run a bunch of tests before releasing GlassFish Gem. These tests, as mentioned earlier, are only to ensure that the latest release of JRuby works nicely with the latest bits of GlassFish.

The first basic test is to check if a simple Rails application can be run using the latest GlassFish Gem. The steps are described next.

First, lets create a database user and grant privileges required by our application:

~/tools >sudo mysql Welcome to the MySQL monitor.  Commands end with ; or \g. Your MySQL connection id is 30 Server version: 5.1.30 MySQL Community Server (GPL) Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the buffer. mysql> create user duke@localhost identified by ‘glassfish’; Query OK, 0 rows affected (0.00 sec) mysql> grant all on runner_development.* to duke@localhost identified by ’glassfish’; Query OK, 0 rows affected (0.03 sec) mysql> grant all on runner_production.* to duke@localhost identified by ’glassfish’; Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> exit; Bye

The “runner_development” and “runner_production” databases will be created later. And the database are dropped and created fresh for every test run.

Now lets try to create our first Rails application using JRuby and run it using GlassFish gem:

1. Download and unzip JRuby 1.2.0 RC1.
2. Install Rails and GlassFish Gem as:
   

   ~/tools/jruby-1.2.0RC1 >./bin/jruby -S gem install rails glassfish JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Successfully installed activesupport-2.2.2 Successfully installed activerecord-2.2.2 Successfully installed actionpack-2.2.2 Successfully installed actionmailer-2.2.2 Successfully installed activeresource-2.2.2 Successfully installed rails-2.2.2 Successfully installed rack-0.9.1 Successfully installed glassfish-0.9.2-universal-java 8 gems installed Installing ri documentation for activesupport-2.2.2… Installing ri documentation for activerecord-2.2.2… Installing ri documentation for actionpack-2.2.2… Installing ri documentation for actionmailer-2.2.2… Installing ri documentation for activeresource-2.2.2… Installing ri documentation for rack-0.9.1… Installing ri documentation for glassfish-0.9.2-universal-java… Installing RDoc documentation for activesupport-2.2.2… Installing RDoc documentation for activerecord-2.2.2… Installing RDoc documentation for actionpack-2.2.2… Installing RDoc documentation for actionmailer-2.2.2… Installing RDoc documentation for activeresource-2.2.2… Installing RDoc documentation for rack-0.9.1… Installing RDoc documentation for glassfish-0.9.2-universal-java…

3. Create a new app as:
   

   ~/tools/jruby-1.2.0RC1/samples/rails >../../bin/jruby -S rails runner -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

4. Install MySQL JDBC ActiveRecord adapter as:
   

   ~/tools/jruby-1.2.0RC1/samples/rails >../../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-0.9 Successfully installed jdbc-mysql-5.0.4 Successfully installed activerecord-jdbcmysql-adapter-0.9 3 gems installed Installing ri documentation for activerecord-jdbc-adapter-0.9… Installing ri documentation for jdbc-mysql-5.0.4… Installing ri documentation for activerecord-jdbcmysql-adapter-0.9… Installing RDoc documentation for activerecord-jdbc-adapter-0.9… Installing RDoc documentation for jdbc-mysql-5.0.4… Installing RDoc documentation for activerecord-jdbcmysql-adapter-0.9…

   More details on configuring this adapter here.

5. Create a simple scaffold:
   

   ~/tools/jruby-1.2.0RC1/samples/rails/runner >../../../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/       . . .       create    test/fixtures/runners.yml       create    db/migrate       create    db/migrate/20090226171752_create_runners.rb

6. Edit “config/database.yml” to use the JDBC adapter and specify database username/password. Change:
   

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

   to

   development:   adapter: jdbcmysql   encoding: utf8   database: runner_development   pool: 5   username: duke   password: glassfish   socket: /tmp/mysql.sock

   The change is highlighted in bold letters.

7. Create and migrate the database as:
   

   ~/tools/jruby-1.2.0RC1/samples/rails/runner >../../../bin/jruby -S rake db:create (in /Users/arungupta/tools/jruby-1.2.0RC1/samples/rails/runner) ~/tools/jruby-1.2.0RC1/samples/rails/runner >../../../bin/jruby -S rake db:migrate (in /Users/arungupta/tools/jruby-1.2.0RC1/samples/rails/runner) ==  CreateRunners: migrating ================================================== — create_table(:runners)    -> 0.1330s    -> 0 rows ==  CreateRunners: migrated (0.1340s) =========================================

   The default RAILS_ENV is DEVELOPMENT so there is no need to specify any addtional arguments.

8. And then run the application as:
   

   ~/tools/jruby-1.2.0RC1/samples/rails/runner >../../../bin/jruby -S glassfish Feb 26, 2009 10:30:10 AM com.sun.enterprise.glassfish.bootstrap.ASMainStatic start INFO: Cache not present, will revert to less efficient algorithm Feb 26, 2009 10:30:10 AM com.sun.enterprise.glassfish.bootstrap.ASMainStatic findDerbyClient INFO: Cannot find javadb client jar file, jdbc driver not available Feb 26, 2009 10:30:10 AM APIClassLoaderService createAPIClassLoader INFO: APIClassLoader = java.net.URLClassLoader@14a66e3f no resource bundle found for version, using default GlassFish version Feb 26, 2009 10:30:11 AM AppServerStartup run INFO: [Thread[GlassFish Kernel Main Thread,5,main]] started Feb 26, 2009 10:30:11 AM com.sun.enterprise.v3.services.impl.GrizzlyProxy start INFO: Listening on port 3000 Feb 26, 2009 10:30:11 AM com.sun.enterprise.v3.admin.adapter.AdminEndpointDecider setGuiContextRoot INFO: Admin Console Adapter: context root: /_____admingui Feb 26, 2009 10:30:11 AM com.sun.enterprise.v3.admin.adapter.AdminConsoleAdapter setStateMsg INFO: The Admin Console Application is not yet installed.

   After adding few entries, the output at “http://localhost:3000/runners” looks like:

   

   So we are able to create a trivial Rails application and run it using GlassFish Gem, that passes Test#1.

The subsequent blogs will show the remainder of tests.
