Rails 2.1 on GlassFish - it works!

Posted by arungupta on June 19, 2008 at 6:44 AM PDT

Rails 2.1 was href="http://weblog.rubyonrails.org/2008/6/1/rails-2-1-time-zones-dirty-caching-gem-dependencies-caching-etc">released
earlier this month. GlassFish
provides a complete href="http://developers.sun.com/appserver/reference/techart/rails_gf/">development/deployment
environment for Rails applications. Some of the main reasons
for using GlassFish (instead of WEBrick or Mongrel)
are:

Identical Development and Deployment environment
Multiple Applications can be deployed on one Container
Multiple requests can be handled by a single application
(with no extra configuration)
Out-of-the-box Clustering, Load Balancing and High
Availability
Database connection pooling
Co-hosting Rails and Java EE applications

More details are available in href="http://developers.sun.com/appserver/reference/techart/rails_gf/">Rails
powered by the GlassFish Application Server. This blog
provides detailed instructions to get started with Rails 2.1
on GlassFish.

Install Rails 2.1 in a href="http://dist.codehaus.org/jruby/jruby-bin-1.1.2.zip">JRuby

Edit line 44 of "config/environment.rb" to change the
default timezone from "UTC" to "Pacific Time (US & Canada)".
The updated line looks like:

cellpadding="2" cellspacing="2">

config.time_zone = 'Pacific Time (US & Canada)'
Creating a new scaffold entry shows the following screen:

src="http://blogs.sun.com/arungupta/resource/ror/rails21-v3-tp2-new-runner.png">

Notice how default timezone is selected using href="http://blogs.sun.com/arungupta/resource/ror/rails21-v3-tp2-new-runner.png">Rails
2.1 Time Zone Support. After creating couple of entries (as
described in href="http://blogs.sun.com/arungupta/entry/totd_28_getting_started_with">TOTD
#28), the page at "http://localhost:8080/runner/distances"
looks
like:

src="http://blogs.sun.com/arungupta/resource/ror/rails21-v3-tp2-runner-entries.png">

Notice how "-0700" is shown which is the offset for US Pacific Time
during daylight savings.

The same application can also be easily deployed on href="http://rubyforge.org/projects/glassfishgem/">GlassFish
v3 Gem.
Let's see how:
