Book Overview

With the release of the Java 2 Platform, Enterprise Edition (J2EE), Sun Microsystems have firmly established Java as a truly viable technology for distributed and enterprise development. This book is about how to develop server-side Java applications based on the J2EE specification, and the practical aspects of real-world design using the J2EE technologies.

This book demonstrates how the J2EE architecture allows you, the developer, to concentrate on writing the key logic for your business component. Through comprehensive coverage of the servlet, JavaServer Pages and Enterprise JavaBeans technologies, this book demonstrates how to design and construct secure and scalable Java n-tier applications. You'll see how JSP pages allow you to separate business and presentation logic, how EJBs can be used to model your data, and how to integrate with other systems using CORBA, XML and the Java Messaging Service.

Who is this book for?

This book is for professional Java developers who want to employ Java as the platform for their distributed, enterprise applications. It provides a comprehensive guide to the J2EE APIs implemented by J2EE licensed application servers.

Knowledge of the Java programming language is required, and familiarity with the fundamentals of distributed development would be useful.
