Does heroku support jruby. I am trying to implement a Rails 3.2.3 app using jruby on heroku but I get following error
2012-04-03T20:21:02+00:00 app[web.1]: /app/vendor/bundle/ruby/1.9.1/gems/activesupport-3.2.3/lib/active_support/dependencies.rb:251:in `require': Please install the postgresql adapter: `gem install activerecord-postgresql-adapter` (no such file to load -- java) (LoadError)
how do i solve this problem?
here is my
source 'https://rubygems.org' gem 'rails', '3.2.3' # Bundle edge Rails instead: # gem 'rails', :git => 'git://github.com/rails/rails.git' gem 'activerecord-jdbcmysql-adapter' gem 'activerecord-jdbcpostgresql-adapter' gem 'devise' gem 'jruby-openssl' gem 'json' # Gems used only for assets and not required # in production environments by default. group :assets do gem 'sass-rails', '~> 3.2.3' gem 'coffee-rails', '~> 3.2.1' # See https://github.com/sstephenson/execjs#readme for more supported runtimes gem 'therubyrhino' gem 'uglifier', '>= 1.0.3' end gem 'jquery-rails'
I've been looking into this a bit as well, and found this link to be helpful https://github.com/jkutner/jruby-trinidad-heroku
It shows how to get a rack app running on trindad/jruby git clone git://github.com/jkutner/jruby-trinidad-heroku.git BUNDLER_GEMFILE=Jemfile bundle gem install heroku heroku create --stack cedar --buildpack http://github.com/heroku/heroku-buildpack-java git push heroku master
I realize you are trying to do rails, not rack, but I think this would be a good starting place. If you can get this to work, then you can try to bring in just rails (no db), and slowly build it up.
Unless someone has a more complete example of Rails on jRuby on heroku.
Heroku supports build pack so that we can run most of languages. You can use JRuby build pack to install your app: http://carlhoerberg.github.com/blog/2012/03/29/run-jruby-on-heroku/
