Rails application not starting - ruby-on-rails

Question

I have a new application that is giving me errors when I do
rails server
Here is the error:
/home/agenadinik/.rvm/gems/ruby-1.9.2-p180/gems/railties-3.0.7/lib/rails/script_rails_loader.rb:11: warning: Insecure world writable dir /home/agenadinik in PATH, mode 040777

It seems to be complaining about my config.ru file. Here it is:
# This file is used by Rack-based servers to start the application.
require ::File.expand_path('../config/environment', __FILE__)
run Udfr::Application
Here is my environment.rb file:
# Load the rails application
require File.join(File.dirname(__FILE__), 'boot')
require File.expand_path('../application', __FILE__)
if RUBY_PLATFORM =~ /java/
require 'rubygems'
RAILS_CONNECTION_ADAPTERS = %w(jdbc)
end
# Initialize the rails application
Rails::Initializer.run do |config|
Udfr::Application.initialize!
I changed that file according to these instructions:

Any idea what the problem is?

Answer 1

The instructions you followed are for Rails 2 and will not work with your Rails 3 app.
The updated instructions for getting Ruby on Rails to work on jruby are to edit your gemfile and place your gem requirements there.
In Gemfile:
if defined?(JRUBY_VERSION)
gem 'activerecord-jdbc-adapter'
end
Then run bundle.
