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 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

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
