In this book, John Hunt and Chris Loftus take you through the core technologies that make up the Enterprise Edition of the Java 2 platform (J2EE). They cover all the aspects of J2EE that both professionals and students need to know to build multi-tier enterprise applications in Java - the technologies, the design methodology and design patterns. Whether you are a professional or student, this book will help equip you with the skills you need to build enterprise wide applications in Java. Key Topics Includes design issues using J2EE patterns Covers all parts of the enterprise application J2EE Uses an integrated example that spans the chapters to be built up by the reader More accessible and less daunting than a lot of the competition A coherent whole, rather than independent separate chapters (as with some rivals) Features and Benefits Provides an overview of J2EE technologies and their benefits. Discusses architectural design issues using J2EE patterns. Looks at the issues of designing and building multi-tier J2EE applications. Includes fully worked examples, built up throughout the book, which enable you to quickly develop your own multi-tier applications. About the Authors: Dr. John Hunt is Technical Director at JayDeeTechnology Ltd. He runs industrial courses, including server-side Java technologies. He also leads development projects for government and blue chip organisations using Java, J2EE, XML and C#. Chris Loftus is a Teaching Fellow at the Department of Computer Science at the University of Wales, Aberystwyth. He has taught Java-based courses, including J2EE, both in university and industry.

Industry Reviews

From the reviews: "In this single volume ! we are introduced to all the major parts of the J2EE platform. ! the book does provide a wide-ranging introduction to the J2EE platform. That it does so at a reasonably detailed level is a key strength. Entire books have been written about each of the technologies included here, so to have it all in one place makes this a good reference to have around. ! This book provides a very good primer on J2EE." (Pan Pantziarka, Application Development Advisor, Vol. 8 (3), 2004)
