JRuby-on-Rails deployed on GlassFish - Success Story
Posted by arungupta on January 29, 2008 at 06:32 AM | Comments (3)
There are several reasons you may deploy JRuby-on-Rails application on GlassFish:
- Java EE is a long tested deployment platform and GlassFish
is Java EE 5 compliant.
- GlassFish "green" deployment model - just create a WAR and
dump it in
autodeploy directory. Typical Rails deployment requires to spawn
multiple Mongrels, front-ended by Apache and then manage them through
Capistrano.
- Java EE and Ruby-on-Rails applications can be easily
integrated in one container. This allows to host JRuby-on-Rails
applications in organization who have already made investment in Java
EE.
- GlassFish comes with out-of-the-box clustering and
high-availability support. Rails applications can certainly benefit
from them.
- GlassFish offers database connection pooling allowing you
to reuse your database connections.
- Last, but not the least, JRuby-on-Rails can leverage the
extensive set of Java libraries.
I'm working on an article that will explain each of these in detail. In
the meanwhile here is a live success story.
mediacast.sun.com
(provides a public place for Sun
employees to store large media files) released their version 2.0 -
completely rewritten using JRuby-on-Rails and deployed on GlassFish.
Igor has good details is his blog.
Here are some excerpts:
Development environment: NetBeans
6, Mercurial
plugin, WEBrick,
GlassFish v2 UR1,
MySQL
Deployment environment: 2 Load-balanced T2000,
Solaris
10, Sun
Java System Application Server 9.1 U1, JDK 6, MySQL
He has explained the pain points and areas of improvements very
clearly. We are aware of the performance problems and already working
on them!
Let us know if you have had success with deploying JRuby-on-Rails
on
GlassFish. Read all GlassFish
success stories.
UPDATE (Feb 8):

Hi Arun. Great job... I've been waiting for Sun to release something on JRoR. We released a JRoR app back in November (at Oracle). Not sure if you've read about it yet -> http://oracleappslab.com/2007/11/21/mix-jruby-on-rails-small-teams-agile-and-its-effects-on-the-world/
This is the year for JRuby on Rails!

I wonder if you could talk specifically about threading.
Once you're in Glassfish, how are multiple simultaneous requests handled?

JRuby/GlassFish process models are explained in detail at:
http://blogs.sun.com/arungupta/entry/ruby_jruby_process_models_explained
For each request received, JRuby runtime is spawned which delegates the request to Rails and then process the response.
