I am having excellent experience in Java and eclipse, But new to Ruby on Rails, can anyone point to the best resources, or step which i can follow to start with Ruby On Rails development and enviornment setup for windows.
I think Rails Tutorial is a best place for you to start learning, setup environment and development for Ruby on Rails:
Rails Tutorial
Rails Guide and about API
Some videos Rails Cast
Book Rails 3 way
One more thing, I think many Rails developers will not build Rails application on Window.
I have been using it fine. You just have to setup the correct run config to run rails -s

I am new to the rails programming. I was building my first rails application.
In internet I was searched how to run the rails application in rails 2.3.14 version. But I did not get the answer.
I know how to start the server. But I don't know how run the rails application.
Can anyone please explain me how to run the rails application in 2.3.14 version.
You start a server in Rails 2.3 with:
./script/server start
That starts a local server in development mode, browse to http://localhost:3000 to see your application.
You might want to have a look at the other scripts in the scripts folder too, you will find a subset of modern rails commands. Like
./script/console
to open the Rails console.
But I wouldn't recommend to learn Rails with a 2.3 application. 2.3 has many differences to modern Rails 4.2 or 5.0 application.
I just started to learn Ruby on Rails. Now I created a simple project and it worked fine in IDE (Aptana). My question is: How can I deploy it in Glassfish?
Some online articles mentioned JRuby and some Glassfish Gem, but there's no details on how to do it. Do I have to use JRuby and is there a step by step tutorials that tell me how to deploy my rails project in Glassfish?
Thanks.
Yes, you have to use JRuby as Glassfish is a Java EE Application Server.
Here is a tutorial:

I'm beginning to learn Ruby on Rails, I installed the latest ubuntu release on a VMWare machine and started the ruby on rails setup process using the mini-guide in this online book (which was recommended in stack overflow more than once). I'm wondering:
As part of my environment setup process I installed RubyGems and used it to install Rails (which is, if I understand correctly - a gem itself) the first time.
Now, when creating a new project using rails new project_name I later on edit the Gemfile and specify "rails '{version}'", which, from what I understand, installs the Rails gem in the context of the project (after using bundle install)...
Why would I need both of them? I'm kind of confused and would be more than happy if someone could shed some light over this...
Yes, this is a bit confusing.
When you run rails new project_name, you are using whatever rails executable is available in your shell to start a new rails project. To see what version this is, run rails —version. This does not "install the rails gem" — it just generates the tree of files to get you started on a new rails project.
You'll then specify in your Gemfile which version of rails your project will use.
So, be sure to have the latest version of rails available to your shell when you generate your new project, so that you get the newest version of the files it generates.
Is all I need mod_rails and ruby 1.9.2? What is the best resource for production setup of rails.
The first time I deployed a Rails app, I simply read this.
Once this config done, I recommend you learn how to use capistrano.
Trying to follow the "Ruby on Rails 3 Tutorial" and running rails s, getting the following error:
[path]\config.ru:1 in 'require': no such file to load -- fake_app
I've got the location of fake_app.rb in the PATH (which I presume is what rails/rack is trying to find)
Contents of config.ru are the default generated:
require "fake_app"
run Rack::Test::FakeApp
I am running rails 3.0.8 and Windows 7
Thanks for helping this complete novice out!
Did you generate this with rails new [appname] command? A default Rails 3.0 config.ru file should look more like this:
require ::File.expand_path('../config/environment', __FILE__)
run ApplicationName::Application
If all you've done at this point is install Ruby and Rails, I'd re-run the generator to get something that works.
Also, since you're on Windows, I wanted to recommend Rails Installer for your environment installation and setup. It mitigates a lot of the startup pain.
This is probably the tutorial you are speaking of, but I also highly recommend Michael Hartl's Ruby on Rails Tutorial for a solid introduction to Rails 3. The section about generating your first application may be handy in this situation.
