Rails 2.1 on GlassFish - it works!

Ads by DZone

Rails 2.1 was released earlier this month. GlassFish provides a complete 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 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 JRuby 1.1.2 installation:

~/testbed/rails21/jruby-1.1.2 >bin/jruby -S gem install rails --no-ri --no-rdoc

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

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

Notice how default timezone is selected using Rails 2.1 Time Zone Support. After creating couple of entries (as described in TOTD #28), the page at "http://localhost:8080/runner/distances" looks like:

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 GlassFish v3 Gem. Let's see how:

Let us know on GlassFish Webtier Forum or Webtier Alias if you tried any of your Rails application on GlassFish. Please file bugs at GlassFish Issue Tracker ("V3" as "Found in Version:" and "jruby" as "Subcomponent:") if your app is not working.
