I've create an app on my local MAC MINI machine in Rails 2.2.2 with Webrick it works

Now I want upload the app on Heroku

$ heroku create myapponline --stack cedar

ok, and after I check if I exist the app on heroku

$ git remote -v

> heroku    git@heroku.com:myapponline.git (fetch)
> heroku    git@heroku.com:myapponline.git (push)

Great!

but when I want upload the app

$ git push heroku master

> Counting objects: 124, done. Delta compression using up to 4 threads.

> 
> To git@heroku.com:myapponline.git  ! [remote rejected] master ->
> master (pre-receive hook declined) error: failed to push some refs to
> 'git@heroku.com:myapponline.git'

NOTE when I digit $ git status all files are in the master branch

thank you in advance,

Rails 2.2 is pre-Rack and pre-Bundler, so the normal Rails buildpack won't help you. It's possible, but honestly, you really need to upgrade. There are security implications with running old Rails versions (including 2.2.2 instead of 2.2.3), not to mention the fact that tying yourself to an ancient framework means it'll be difficult to take advantage of the last three years of work in the Ruby ecosystem.

If, after all that, you still have to do this for some reason, fine. You'll need to make your own Procfile spinning up your web server of choice (Webrick? yuck!) on the Heroku-specified port. You'll also need some way of getting all your gems into the slug, either by making a custom buildpack or by hacking Bundler into Ruby 2.2.

And yes, all of that require more Ruby knowledge than upgrading to a reasonable version of Rails.
