JBoss: A Developer's Notebook

There's nothing ordinary about JBoss. What began as an open source EJB container project six years ago has become a fully certified J2EE 1.4 application server with the largest market share, competitive with proprietary Java application servers in features and quality. And with its dynamic architecture, JBoss isn't just a J2EE server. You can alter the services to make J2EE work the way you want, or even throw J2EE away completely.
