Rails GlassFish Gem 0.3.1 now available

Filed under: web2.0 — arungupta @ 5:00 am

Vivek released 0.3.0 version of GlassFish Gem for Rails (a total of 11 issues fixed and resolved – RubyForge & GlassFish Issue Tracker) earlier. But that caused a regression on #4228. And so matching the agility expected by Rails developers, he quickly released 0.3.1. And a wee bit smaller too – 2.68MB for 0.3.1 instead of 2.69MB for 0.3.0.

If you have an existing version of the gem, then you just need to update it:

~/testbed/jruby-1.1 >bin/jruby -S gem update glassfish -r
JRuby limited openssl loaded. gem install jruby-openssl for full support.
http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL
Updating installed gems…
Bulk updating Gem source index for: http://gems.rubyforge.org
Attempting remote update of glassfish
Successfully installed glassfish-0.3.1-universal-java
1 gem installed
Gems updated: glassfish

If the gem has never been installed, then you install it as:

~/testbed/jruby-1.1.2 >bin/jruby -S gem install glassfish
JRuby limited openssl loaded. gem install jruby-openssl for full support.
http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL
Successfully installed glassfish-0.3.1-universal-java
1 gem installed

And make sure next time you have to update the gem instead of installing from scratch ;) For that, just install the gem this time and let us know your feedback on GlassFish Webtier Forum or Webtier Alias. If any of your Rails application do not work then please file bugs at GlassFish Issue Tracker (“V3″ as “Found in Version:” and “jruby” as “Subcomponent:”).

The gem installation may require to set “JAVA_MEM=-Xmx800m” because of the growing memory requirements. Otherwise you may get “Exception in thread “main” java.lang.OutOfMemoryError: Java heap space“.

Try a simple scaffold application to see the output as shown below:

The startup output in the gem console (output from GlassFish) is:

Redmine seems to have issues with Rails 2.1. I’ll play with some other applications later. But have you tried deploying your Rails application on GlassFish gem ? As mentioned above, let us know your feedback on GlassFish Webtier Forum or Webtier Alias and file bugs on GlassFish Issue Tracker.

Details about previous versions are available at 0.2.0, 0.1.2, 0.1.1, 0.1.0.

  1. [Trackback] Substruct is an open-source E-Commerce project written using Ruby-on-Rails framework. It provides a simple e-commerce platform, content management system and customer response system – all in one. I found out about this application from Sang "Passion"…

  2. [Trackback] The default database for Rails 2.0.x application is SQLite3. This database is bundled with Mac OSX Leopard and so makes it really easy to get started with Ruby-on-Rails. But it requires couple of additional steps if you are using JRuby….

  3. Thanks for your detailed tips.

    I installed jruby-1.1.3 and glassfish 0.3.1 (sorry – I had to install from scratch :) and my micro example worked fine.

    So I tried to launch my own (somewhat bigger) project with jruby and glassfish (11 models, 13 controllers, 3 plugins [attachment_fu, open_id_authentication, restful-authentication]) – and with just a minor glitch – it worked.

    I noticed that I have to change my database config to:
    development:
    adapter: jdbcsqlite3
    database: projecttracker/db/development.sqlite3
    timeout: 5000

    And that was it.

    2 questions:
    a) Is there a way to detect the glassfish environment in ruby/rails -> so that I could dynamically add the additional path to the development.sqlite3 file? (Not needed for standalone DBs :)
    b) Is there a way to package my application into a WAR file and deploy only this WAR file on a glassfish (v3) server?

    Comment by Rene A. — July 27, 2008 @ 12:07 pm

  4. Rene,

    I believe a) happens only for SQLite3. Can you file an RFE at:

    https://glassfish.dev.java.net/issues/enter_bug.cgi?issue_type=ENHANCEMENT

    using "jruby" sub-component ?

    Yes, Rails application can be easily bundled into a WAR file as described at:

    http://blogs.sun.com/arungupta/entry/war_based_packaging_and_deployment

    In fact this is a very popular option that s used for deployment.

  5. Hi Arun,

    firstly: many thanks for your efforts in providing a stable deployment solution for the JRuby on Rails environment: your job is already great and will be surely better in future releases!

    Said that, i have migrated from glassfish gem 0.2 to 0.3 and noticed that the AS also log response return messages into the views of my application.

    This does not happens always, but when it does affects both normal HTTP requests and Ajax requests (for example i see the response status into the in-place-editor fields).

    A logging string example:
    HTTP/1.1 200 OK Content-Type: text/html; charset=iso-8859-1 Transfer-Encoding: chunked Date: Tue, 29 Jul 2008 07:34:43 GMT

    Any idea on how to remove this logging?

    Thank you again and greetings.
    Michele
