Rails for J2EE Developer - Ruby for Java Developer

I think it' necessary to compare the right things together:

Ruby is a programming language; Rails (or better: Ruby on Rails - RoR, don't forget there's also Groovy on Rails - Grails) is a complete web framework including it's own persistency layer.

We absolutely agree. The title is just meant to draw in folks who consider themselves "Java programmers". In the book, we explicitly compare the Rails stack to the major players in the Java world: ActiveRecord to Hibernate, ActionController and ActionPack to Struts, etc.

I guess you also mention Rails concepts like "Convention over configuration" and the DRY principle?

Yes, and we're quite careful to distinguish between:

  • things that are specific to Rails
  • things that are specific to Ruby
  • things that are just good ideas and are made easier in Ruby/Rails
  • things that are good ideas and are hard to do in Ruby/Rails
