Owning a copy of Alur, Crupi & Malks "Core J2EE Patterns" myself, I was at first surprised by Seams heretic ways but I then started to realize the many of the patterns are trying to solve problems that really aren't there anymore.

Enjoy your classes, the time for interfaces and factories are when you really have two or more implementations of the same logic etc. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4117475#...
