Announcing GlassFish Gem for Rails

Filed under: web2.0 — arungupta @ 12:02 am

Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic.

Jerome has been working on GlassFish gem for Rails. Read the interesting discussion on dev@glassfish. This blog announces a technology preview of this gem and describes the steps to try it out.

Download GlassFish Gem from here.
If you already have JRuby on Rails configured, then skip this step. Otherwise you need to install JRuby on Rails.
1. Download and Unzip JRuby 1.0.1 from here (lets say JRUBY_HOME).
2. In JRUBY_HOME\bin directory, install Rails plugin using the following command:
  
  jruby -S gem install rails -y --no-rdoc --no-ri
  
  The output of the command looks like:
  
  Bulk updating Gem source index for: http://gems.rubyforge.org Successfully installed rails-1.2.3 Successfully installed activesupport-1.4.2 Successfully installed activerecord-1.15.3 Successfully installed actionpack-1.13.3 Successfully installed actionmailer-1.3.3 Successfully installed actionwebservice-1.2.3
Some platform specific changes listed below are required due to bugs in JRuby 1.0.1.
1. Only on Windows
  1. Edit "JRUBY_HOME\bin\_jrubyvars.bat" and replace
    
    for /r "%JRUBY_HOME%\lib" %%i in (*.jar) do @call "%~dp0_jrubysetcp" %%i
    
    with
    
    for %%i in ("%JRUBY_HOME%\lib"\*.jar) do @call "%~dp0_jrubysetcp" %%i
    
    This change is required because "/r" switch causes the entire tree of the directory to be parsed instead of just including the JARs in JRUBY_HOME/lib directory. More details here. This is filed as bug #1347.
  2. The value of CLASSPATH environment variable increases exponentially with each execution of the gem. Then you start seeing the following error in your command shell:
    The input line is too long. :gotCP was unexpected at this time.
    
    This is a filed as bug #1350. A workaround is to start a new shell when you start seeing the error.
2. Only on Macintosh: "JRUBY_HOME\bin\glassfish_rails" script executable permissions need to be set explicitly. This is filed as bug #1348.
Install the GlassFish gem using the command:

c:\Downloads>\jruby-1.0.1\bin\gem install glassfish-gem-10.0-SNAPSHOT.gem

The output of the command looks like:

Successfully installed GlassFish, version 10.0.0

Notice, you need to invoke this command from the directory where the gem was downloaded.
Create a new rails app using the following command:

%JRUBY_HOME%\bin\jruby -S rails hello

The output of the command looks like:

create create app/controllers create app/helpers create app/models create app/views/layouts create config/environments create components create db create doc create lib create lib/tasks create log create public/images create public/javascripts create public/stylesheets create script/performance create script/process create test/fixtures create test/functional create test/integration create test/mocks/development create test/mocks/test create test/unit create vendor create vendor/plugins create tmp/sessions create tmp/sockets create tmp/cache create tmp/pids create Rakefile create README create app/controllers/application.rb create app/helpers/application_helper.rb create test/test_helper.rb create config/database.yml create config/routes.rb create public/.htaccess create config/boot.rb create config/environment.rb create config/environments/production.rb create config/environments/development.rb create config/environments/test.rb create script/about create script/breakpointer create script/console create script/destroy create script/generate create script/performance/benchmarker create script/performance/profiler create script/process/reaper create script/process/spawner create script/process/inspector create script/runner create script/server create script/plugin create public/dispatch.rb create public/dispatch.cgi create public/dispatch.fcgi create public/404.html create public/500.html create public/index.html create public/favicon.ico create public/robots.txt create public/images/rails.png create public/javascripts/prototype.js create public/javascripts/effects.js create public/javascripts/dragdrop.js create public/javascripts/controls.js create public/javascripts/application.js create doc/README_FOR_APP create log/server.log create log/production.log create log/development.log create log/test.log
Start GlassFish for this newly created app using the following command:

%JRUBY_HOME%\bin\jruby -S glassfish_rails hello
You need to invoke the command from outside the application directory instead of the natural way (script\server start). This will be fixed in the future builds. The output of the command looks like:
Sep 13, 2007 1:32:42 PM com.sun.enterprise.v3.services.impl.GrizzlyAdapter postConstruct INFO: Listening on port 8080 Sep 13, 2007 1:32:42 PM com.sun.enterprise.v3.services.impl.DeploymentService postConstruct INFO: Supported containers : jruby,web,php,phobos Sep 13, 2007 1:32:43 PM com.sun.grizzly.standalone.StaticResourcesAdapter <init> INFO: New Servicing page from: C:\workarea\samples\rails\hello\public C:/jruby-1.0.1/lib/ruby/gems/1.8/gems/actionmailer-1.3.3/lib/action_mail er.rb:49 warning: already initialized constant MAX_LINE_LEN Sep 13, 2007 1:32:51 PM com.sun.enterprise.v3.server.AppServerStartup run INFO: Glassfish v3 started in 8996 ms
Now you can view the default GlassFish web page at "http://localhost:8080".

This verifies the basic installation of the GlassFish gem. Lets add a simple controller to our application.

Add a controller to the application by changing to the directory "hello" and giving the command:

jruby script\generate controller say hello
The output of the command looks like:

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
In hello\app\views\say directory, edit "hello.rhtml" such that it looks like:
<h1>Say#hello</h1> <p>Find me in app/views/say/hello.rhtml</p> <%= @hello_string %>
In hello\a pp\controllers directory, edit "say_controller.rb" such that it looks like:
class SayController < ApplicationController def hello @hello_string = "Hello from Controller!" end end
The page is now accessible at "http://localhost:8080/hello/say/hello".

This is hosted using GlassFish. Of course, the same application can be deployed on WEBrick by giving the command:

jruby script\server webrick start

Try your applications on GlasFish gem and let us know by leaving a comment on this blog or sending an email to users@glassfish or posting to GlassFish forum.

You can also download GlassFish V3 standalone builds from here. The instructions to deploy a Rails application on GlassFish V3 are available here and on V2 here.

I tried again and don’t see this error with a simple hello application. I’m using JRuby 1.0.1 and Rails 1.2.3. Here is what I see …

where hello is application name… i get standard index.html from public directory. But ! I don’t get css, js, and any images, and i have this errors on glassfish_rails. When i see clear page without rails logo.

Comment by Andrzej — October 5, 2007 @ 1:11 pm
What is your environment ? I’m running on Windows Vista and JDK 1.5.0_011. I’m certainly interested in reproducing this error and then I can debug it.

Comment by Arun Gupta — October 5, 2007 @ 1:32 pm
Again I can only repeat – I have exactly the same as Adrzey does
I’ve tried to google around about this error and found this link to source file

http://fisheye5.cenqua.com/browse/~raw,r=1.1.2.4/glassfish/appserv-core/src/java/com/sun/enterprise/v3/server/GrizzlyAdapter.java

found the place in the source about "No adapter registered for…"

// TODO : a better job at error reporting
Utils.getDefaultLogger().info("No adapter registered for : " + req.requestURI().toString());

and it seems that this GrizzliAdapter can’t find resource files. But why?

Maybe I have to correctly setup this `docRoot’ variable?

Charles Nutter wrote in his post
http://headius.blogspot.com/2007/09/end-is-near-for-mongrel.html
about settings
ActionController::AbstractRequest.relative_url_root = "/<app name>/"
ActionController::CgiRequest.relative_url_root = "/<app name>/"
in environment.rb
I tried it but with no success

I have tried on Linux an Windows XP machines. On XP one I had even worse result.

JDK 1.6_01 sorry for I don’t remember the exact minor numbers in jdk version. That was at my office and now I’m already at home.

Comment by Nick — October 5, 2007 @ 1:43 pm
The behavior that "Andrzej" and "Nick" have mentioned can be observed if the URL is specified as :
http://localhost:8080/hello

As Nick mentioned the sample page would be displayed correctly but any gifs do not appear and one would see the following error on the console :
Oct 11, 2007 11:54:13 AM com.sun.enterprise.v3.services.impl.GrizzlyAdapter service
INFO: No adapter registered for : /javascripts/prototype.js
Oct 11, 2007 11:54:13 AM com.sun.enterprise.v3.services.impl.GrizzlyAdapter service
INFO: No adapter registered for : /javascripts/effects.js
Oct 11, 2007 11:54:13 AM com.sun.enterprise.v3.services.impl.GrizzlyAdapter service
INFO: No adapter registered for : /images/rails.png

I have observed this on both Mac and Solaris x86 platforms. But things work correctly if the URL is specified as http://localhost:8080/hello/

So it looks like if one misses out the last slash, somehow there is an issue in getting to the resources.

Need to investigate further why this is happening.

Comment by Pramod Gopinath — October 11, 2007 @ 11:58 am
Arun, I just tested out the Glassfish gem on several Rails applications: Beast, Mephisto, etc and they all exhibited the same problem on OSX with Firefox. Glassfish appears to serve CSS files as Content-type: text/plain which leads to unstyled HTML pages in Firefox. When I use Mongrel with the exact same codebase, the CSS is served as text/css and Firefox renders the pages perfectly. Is this a known issue?

Comment by Mike Perham — October 14, 2007 @ 3:33 pm
As I had reported earlier there is a difference in behavior between http://localhost:8080/hello (does not load images,javascript.. correctly) and http://localhost:8080/hello/ (works correctly)

In glassfish V2 the URl of http://localhost:8080/hello is redirected to http://localhost:8080/hello/

So this is obviously a bug in the grizzly code. Have filed an issue against the web container.

Comment by Pramod Gopinath — October 16, 2007 @ 4:54 pm
Bug, bug … bug!

Many simple problems is in Glassfish V3, but how to posssible is add "future" bug in V3, when in V2 is OK? Who write and develope V3 not using V2 source code as base ? Maybe not use http units test

Ok, I waiting for new GEM with bugfixed version of Glassfish
