Ruby Vs J2EE

Aaron Rustad wrote a pretty good white paper comparing Ruby on Rails with J2EE framework. Those who care to follow programmer productivity metrics and enterprise frameworks will do themselves a favor by reading this.

Ruby's claim of being 10 times more productive than other framework may be better left for performance  debates but there is no doubt about it's capability to provide  faster development cycle and simplicity. Some popular apps written with Rails include Basecamp, 43Things,  and I am sure there are many more in the works right now.
