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 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 app/helpers/application_helper.rb
    create test/test_helper.rb
    create config/database.yml

    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

  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"

  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:

    <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
    => Ctrl-C to shutdown server; call with --help for options
    [2007-11-07 17:22:01] INFO WEBrick 1.3.1
    [2007-11-07 17:22:01] INFO ruby 1.8.5 (2007-11-01) [java]
    [2007-11-07 17:22:01] INFO WEBrick::HTTPServer#start: pid=11245030 port=3000 - - [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
    Nov 8, 2007 2:39:07 PM com.sun.enterprise.v3.services.impl.GrizzlyAdapter postConstruct

[Trackback] 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...
