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.
