The J2EE™ Tutorial, Second Edition, is the complete guide to all major components of the Java 2 Platform, Enterprise Edition (J2EE) version 1.4. Written by members of the J2EE platform team at Sun Microsystems, this is the task-oriented and example-driven book that will have new and intermediate Java programmers building J2EE applications right away.

The first chapters introduce the J2EE 1.4 platform architecture and APIs, the Sun Java System Application Server Platform Edition 8, and the basics of working with XML and Web applications. The greater part of the book is devoted to describing and demonstrating the Java XML, Web-tier, and Enterprise JavaBeans technologies and platform services. Extensive examples and case studies show you how to put these technologies to work in the real world.

The technologies and services detailed include:

Java API for XML Processing (JAXP)
Java API for XML-Based RPC (JAX-RPC)
SOAP with Attachments API for Java (SAAJ)
Java API for XML Registries (JAXR)
Java Servlet
JavaServer Pages (JSP)
JSP Standard Tag Library (JSTL)
JavaServer Faces
Internationalization and localization
Enterprise JavaBeans (EJB)
Transactions
Resource connections
Security
Java Message Service API (JMS API)

The J2EE™ Tutorial, Second Edition, will give you a head start in developing and deploying J2EE applications.

The accompanying CD-ROM includes the tutorial examples (binary and source code) and the J2EE Software Development Kit, Enterprise Edition 1.4 (J2EE 1.4 SDK), which contains the Sun Java System Application Server Platform Edition 8, Java 2 Software Development Kit (J2SE SDK), and BluePrints sample applications.
