You can run Padrino (0.9.29 / 0.10.3 is tested) on JRuby 1.6.4.
You can easily install Padrino on jruby when you use rvm :
$ rvm use --create jruby-1.6.4@padrino
$ gem install padrino
Create Padrino project just as you do when using MRI or REE:
$ padrino g project jrack-test
cd ./jrack-test
and you should edit Gemfile
:
# JRuby deployment requirements
# please add these lines...
gem 'jruby-openssl'
gem 'jruby-rack'
gem 'warbler'
Now you can go:
$ bundle
Then, create the test controller:
padrino gen controller index get:index get:hello get:show_path
A controller sample is here:
# index.rb
JrackTest.controllers :index do
get :index do
"Hello, JPadrino!"
end
get :hello, :map => '/:id' do
"Hello, #{params[:id]}!"
end
get :show_path, :map => '/show-path/*urls' do
"You accessed: #{params[:urls].inspect}"
end
end
Then run:
padrino start
To run JRuby on 1.9 compat mode:
alias padrino='jruby --1.9 -S padrino'
padrino start
You can access localhost:3000
as you run padrino on MRI…
Now you should have installed warbler
gem, so you can:
warble config
Edit config/warble.rb
if you want to apply some customizations. You can access JRuby-Rack official README and Warbler rdoc.
For example, if you want to deploy the app to server root directory, just add to config/warble.rb
:
config.jar_name = "ROOT"
Deploying with JRuby on 1.9 compat mode:
config.webxml.jruby.compat.version = "1.9"
If you are ready, run:
warble war
You would get jrack-test.war
(the same name as your project diresctory name), and you can deploy this war file to tomcat! I tested on tomcat 6.0.20, and it works well with quick response.
