For the past month, all the Radiant-jRuby installation instructions that I have found did not perform as advised. From what I have determined, the root of the issue was Radiant-jRuby was unable to create cache files.  Thus disabling cache allowed Radiant to function properly with jRuby.

To disable caching, comment the config.middle.use argument in environment.rb file.

# config.middleware.use ::Radiant::Cache

If caching is incredibly important, the Rack::Cache module seems to function without any errors, however I haven’t figure out where the cache files are saved.  To enable caching with Rack just update the config.middleware.use argument in environment.rb file.

config.middleware.use ::Rack::Cache

Here below are the instructions I used to enable Radiant on jRuby and Tomcat based on the Radiant CMS instructions at http://kenai.com/projects/jruby/pages/Radiant_CMS

Obtaining Gems

The command below is under the assumption all the required jdbc mysql adapters have been installed. If not please include activerecord-jdbcmysql-adapter gem.

jruby -S gem install –no-ri –no-rdoc radiant radius rack-cache warbler

Create Project and Configuration

Lets create a Radiant mysql application in a directory.

jruby -S radiant –database=mysql radiantblog

Before the application data is created, the database.yml needs to be configured. Simply update the adapter to “jdbcmysql” instead of “mysql”. Here is what the production configuration would look like.

production:
adapter: jdbcmysql
database: radiant
username: username
password: password
host: localhost

With the database.yml configured, the database can now be bootstrapped.

jruby -S rake production db:bootstrap

Lets run the server to test the app and check it at localhost:3000

jruby -S script/server -e production

Deployment

The only deployment that I utilize is with Tomcat using the warbler gem.  Here is the minimum configurations I used starting off with the command to generate the warbler configuration file

jruby -S warble config

warble.rb configuration:

Warbler::Config.new do |config|
config.dirs = %w(cache config db log public script vendor tmp)
config.gems += ["activerecord-jdbcmysql-adapter", "radiant",
"jruby-openssl", "radius", "rack-cache"]
config.gem_dependencies = true
config.war_name = “ROOT”
end

The reason why the config.war_name is ROOT is to avoid any potential Radiant Routing issues. Next build the war file with the following command.

jruby -S warble war

After running the above command, move the newly created file, ROOT.war, to the Tomcat web directory. The URL, localhost:8080, should now render your newly created Radiant blog.
