What started 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 application servers in features and quality Java. You can change the services to make J2EE to work the way you want, or even throw J2EE myself fully. After more than a million downloads, many JBoss users are no longer trying to get out on internal test boxes, but rolled out on production machines:. JBoss A Developer's Notebook takes you on a complete tour of JBoss in a very unique way: rather than a long discussion, you will find code - lots of code. That includes exploring the many server configurations: from bare features for simple applications, for lightweight J2EE configuration, to everything JBoss has in store-including Hibernate and Tomcat. JBoss: A Developer's Notebook also introduces the management console, web services messaging features, enhanced monitoring capabilities, and shows you how to improve performance.
