RubyMine does not have any support for Java and does not recognize Java classes - JRuby is only supported as a target platform for running regular Ruby code. Full Java/Ruby interoperability is supported in IntelliJ IDEA with the Ruby plugin.

Getting Started with Rails


rails new blog
cd blog
rake db:create
rake -T
rails server
rails generate controller home index
del public\index.html
edit config\routes.rb
    root :to => "home#index"

Same Chinese error message... "Learn Mandarin" now on my todo list...

echo "export PATH=/var/lib/gems/1.8/bin:$PATH" >> .bashrc
mkdir www; cd www 
rails new blog
cd blog
sudo apt-get install libsqlite3-dev
sudo gem install sqlite3-ruby
sudo gem install uglifier
