InfoQ: Introduction to JBoss Seam

InfoQ: Introduction to JBoss Seam: "JBoss Seam is a 'lightweight framework for Java EE 5.0'. What does that mean? Isn't Java EE (Enterprise Edition) 5.0 itself a collection of 'frameworks'? Why do you need another one that is outside of the official specification? Well, we view Seam as the 'missing framework' that should have been included in Java EE 5.0. It sits on top of Java EE 5.0 frameworks to provide a consistent and easy-to-understand programming model for all components in an enterprise web application. It also makes stateful applications and business process-driven applications a breeze to develop. In another words, Seam is all about developer productivity and application scalability."
