Running Old Rails App

Thanks for the reply...Environment.rb look like this .... but version is not mentioned
<code>

# Be sure to restart your server when you modify this file

# Specifies gem version of Rails to use when vendor/rails is not present
#RAILS_GEM_VERSION = '2.3.4' unless defined? RAILS_GEM_VERSION

# Bootstrap the Rails environment, frameworks, and default configuration
require File.join(File.dirname(__FILE__), 'boot')

Rails::Initializer.run do |config|
  # Settings in config/environments/* take precedence over those specified here.
  # Application configuration should go into files in config/initializers
  # -- all .rb files in that directory are automatically loaded.

  # Add additional load paths for your own custom dirs
  # config.load_paths += %W( #{RAILS_ROOT}/extras )

  # Specify gems that this application depends on and have them installed with rake gems:install
  # config.gem "bj"
  # config.gem "hpricot", :version => '0.6', :source => "http://code.whytheluckystiff.net"
  # config.gem "sqlite3-ruby", :lib => "sqlite3"
  # config.gem "aws-s3", :lib => "aws/s3"

  # Only load the plugins named here, in the order given (default is alphabetical).
  # :all can be used as a placeholder for all plugins not explicitly named
  # config.plugins = [ :exception_notification, :ssl_requirement, :all ]

  # Skip frameworks you're not going to use. To use Rails without a database,
  # you must remove the Active Record framework.
  # config.frameworks -= [ :active_record, :active_resource, :action_mailer ]

  # Activate observers that should always be running
  # config.active_record.observers = :cacher, :garbage_collector, :forum_observer

  # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
  # Run "rake -D time" for a list of tasks for finding time zone names.
  #config.time_zone = 'UTC'

  # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
  # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}')]
  # config.i18n.default_locale = :de
end

According to your environment.rb file your app uses 2.3.4 version:

RAILS_GEM_VERSION = '2.3.4' unless defined? RAILS_GEM_VERSION

And you hav 2.3.10. So to be able to run the app, you should either to install the exact rails version used by it (2.3.4 in your case) or try to modify it to yours one (instead of 2.3.4 type in 2.3.10).
After you get your environmeent set up, just run migration as I explained earlier.
If everything is OK, you can run the server:

$ script/server
#or on Windows
c:/your_app_folder/> ruby script/server

You can find all the details at Rails 2.3.11 Guides
And the correct tags to post your code snippest is

code and /code surrounded with brackets.

Rails is not difficult at all compared with Java for example. The problem is that there is a GREAT difference between rails 2.3* and 3.0 versions done in project structure and how the things are linked together.
- Try first to configure your environment to use Rails 2.3.* version as I explained earlier (install all minimal needed gems to create a Rails application)
- Check if everything works fine by creating a simple RoR project using the same DB adapter as you project does.
- Then try step by step to identify your project configuration problem.

As you know, there is a gem runtime dependency, so try to check it for every gem used by your project by going to http://www.rubygems.org and finding the needed gem. Every time, once a gem found, you can see its runtime dependencies; So just try to install them.
Sure it is enough tedious. I agree that it was more difficult at that time to manage gems used by a project; Now thanks to bundler it is more easy. like with Maven tool in Java world.
