So you’ve written a Rails app and you want to show it off to your boss at work because you know that it will impress them. Problem is that your company only uses Java and won’t consider it for their production environment if it can’t be deployed under a JVM. Let’s go:
- Install JRuby
- Install the required gems for Ruby on Rails to work with JRuby
jgem install mongrel activerecord-jdbcsqlite3-adapter rails
- Install the gems particular to your application
jruby -S rake gems:install
- Update your database.yml file, prefixing your adapter with jdbc
- Start your JVM
- Sit back and wait for promotion
- Some notes on whats going on above:
Detailed installation instructions for JRuby can be found on their wiki.
jruby -S rake command is very important as the -S switch ensures that the rake command is sourced from the JRuby home, not the system path which would contain a native Ruby install
ActiveRecord-JDBC can handle most any database you can think of in a corporate environment.
If you wish to use another database, there are some gems already pre-packaged, more details on the github page.
