Ruby on Rails vs. Struts
Brian McCallister has put together a nice tutorial titled "Rails for Struts-ters (Part 1)". In it, he compares a Struts Action to a Rails ActionController (I think that's the right link).
After looking at the various introductory tutorials for RubyOnRails, a lot of people seem to come away thinking it is a simple CRUD framework -- mostly because of Scaffolding. A common theme seems to be, "well, it looks fast for slapping together a prototype, but when you need control, you it ain't there." I can see why people think that way, after watching the 10-minute video, and the reading the ONLamp tutorial. So here is a stab at a guided tour, using Struts as a point of reference.
Good stuff Brian - can't wait for the next tutorial.
