Typo is an open-source Blogging Engine written using Ruby-on-Rails framework. It provides a lean engine that makes blogging easy. It's main attribtues are ease of use, usability, beauty and excellent support of web standards.

I found out about this application from Sang "Passion" Shin's Lab 5543 (part of FREE 20-week course on Ruby-on-Rails started on Jul 15, 2008). But instead of using standard WEBrick/Mongrel deployment, I describe the steps to deploy this application using GlassFish v3 that supports native deployment of Rails applications. 

1. Typo can be installed as Gem or from Sources. Installing as gem gives the following error:
   
   

   JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL Building native extensions.  This could take a while... /Users/arungupta/tools/rails20/jruby-1.1.3/lib/ruby/1.8/mkmf.rb:7: JRuby does not support native extensions. Check wiki.jruby.org for alternatives. (NotImplementedError)         from /Users/arungupta/tools/rails20/jruby-1.1.3/lib/ruby/1.8/mkmf.rb:1:in `require'         from extconf.rb:1 ERROR:  Error installing typo:         ERROR: Failed to build gem native extension. /Users/arungupta/tools/rails20/jruby-1.1.3/bin/jruby extconf.rb install typo Gem files will remain installed in /Users/arungupta/tools/rails20/jruby-1.1.3/lib/ruby/gems/1.8/gems/mysql-2.7 for inspection. Results logged to /Users/arungupta/tools/rails20/jruby-1.1.3/lib/ruby/gems/1.8/gems/mysql-2.7/gem_make.out

   
   This is discussed here. In the meanwhile, download and unzip Typo 5.1.2 as:
   
   

   ~/samples/jruby >unzip ~/Downloads/typo-5.1.2.zip Archive:  /Users/arungupta/Downloads/typo-5.1.2.zip    creating: typo-5.1.2/    creating: typo-5.1.2/app/    creating: typo-5.1.2/app/apis/    . . .   inflating: typo-5.1.2/vendor/uuidtools/lib/uuidtools.rb    inflating: typo-5.1.2/vendor/uuidtools/rakefile    inflating: typo-5.1.2/vendor/uuidtools/README

2. Create the database:
   
   

   ~/samples/jruby >sudo mysqladmin create typo_dev

   
   Typo 5.1.x works with Rails 2.0.x only and so migrate as shown below:
   
   

   ~/samples/jruby/typo-5.1.2 >~/tools/rails20/jruby-1.1.3/bin/jruby -S rake db:migrate (in /Users/arungupta/samples/jruby/typo-5.1.2) == 1 InitialSchema: migrating ================================================= -- create_table(:users)    -> 0.0377s -- create_table(:articles)    -> 0.0189s -- add_index(:articles, :permalink)    -> 0.0094s -- create_table(:categories)    -> 0.0069s  . . . == 69 AddModulesToProfile: migrating ========================================== -- add_column(:profiles, :modules, :text)    -> 0.0072s == 69 AddModulesToProfile: migrated (0.0454s) ================================= == 70 AddUsersToNonAdmins: migrating ========================================== == 70 AddUsersToNonAdmins: migrated (0.0488s) =================================


Typo 5.2 (scheduled in 3 days) will work with Rails 2.1.

3. Download GlassFish (nightly, promoted or build-your-own) and install by unzipping. I tried the nightly of 8/24 as:
   
   

   ~/tools/glassfish/v3/8-24 >unzip ~/Downloads/glassfish-snapshot-v3-prelude-08_24_2008.zip Archive:  /Users/arungupta/Downloads/glassfish-snapshot-v3-prelude-08_24_2008.zip    creating: glassfish/    creating: glassfish/docs/    creating: glassfish/docs/css/    creating: glassfish/docs/graphics/ . . .   inflating: glassfish/lib/templates/login.conf    inflating: glassfish/lib/templates/profile.properties    inflating: glassfish/lib/templates/server.policy

4. Start GlassFish as:
   
   

   ~/tools/glassfish/v3/8-24/glassfish >java -DJRUBY_HOME=/Users/arungupta/tools/rails20/jruby-1.1.3 -jar modules/glassfish-10.0-SNAPSHOT.jar Aug 26, 2008 5:56:10 PM com.sun.enterprise.glassfish.bootstrap.ASMain main INFO: Launching GlassFish on Apache Felix OSGi platform Welcome to Felix. ================= Aug 26, 2008 5:56:11 PM HK2Main start INFO: contextRootDir = /Users/arungupta/tools/glassfish/v3/8-24/glassfish/modules Aug 26, 2008 5:56:11 PM OSGiFactoryImpl initialize . . . INFO: APIClassLoader = Class Loader for Bundle [GlassFish-Application-Common-Module [66] ] Aug 26, 2008 5:56:13 PM CommonClassLoaderManager Skipping creation of CommonClassLoader as there are no libraries available INFO: urls = [] Aug 26, 2008 5:56:13 PM com.sun.enterprise.v3.server.AppServerStartup run INFO: Glassfish v3 started in 2176 ms

5. And deploy Typo as:
   
   

   ~/samples/jruby >~/tools/glassfish/v3/8-24/glassfish/bin/asadmin deploy typo-5.1.2 Command deploy executed successfully.

The application is available at "http://localhost:8080/typo-5.1.2" and some of the screenshots follow:

















Also check out Redmine, Substruct and Mephisto on GlassFish v3. There are some performance issues when running Typo on GlassFish and this is tracked at Issue #5662.

If your Rails application does not work on the gem, file bugs here with "jruby" as "subcomponent" (default version is "v3").
