Rails - Jun 2006 - Good Howto for web service/API with Rails 1.1?

Hi,

does anyone know a good howto for web services with rails 1.1? I
wanted to do it with the new REST web-service support as in
http://72.14.221.104/search?q=cache:AEshEfiLu2wJ:www.jamis.jamisbuck.org/articles/2006/03/27/web-services-rails-style+rails+api&hl=de&gl=de&ct=clnk&cd=57
but I don''t find a good tutorial :(

Thanks,
Beate
