This new (second) edition of the book updates the contents to cover J2EE 1.4. As the title implies this is very much an introductory text which aims to cover the full range of technologies that make up the J2EE platform. While the book assumes little prior knowledge of J2EE, it does assume some knowledge of Java (in other words knowledge of J2SE).
The book opens with a scene setting chapter which surveys the landscape of n-tier development and gives a birds-eye view of what J2EE is and what it's supposed to do. This is followed up with a more detailed view of the different technologies and components (from Enterprise Java Beans to servlets to JSP, from HTTP to XML and more) which are included and finishes with a walk-through of the installation and configuration of Sun's J2EE reference installation. The book is largely structured around a single worked example project, and this is introduced and discussed as well.
