Скачать Expert One-on-One J2EE Design and Development – Rod Johnson



The results of using J2EE in practice are often disappointing — applications are often slow, unduly complex, and take too long to develop. I believe that the problem lies not in J2EE itself, but in that it is often used badly. Many J2EE publications advocate approaches that, while fine in theory, often fail in reality, or deliver no real business value.

In this book I offer a real-world, how-to guide so that you can make J2EE work in practice. I draw on my experience of designing successful high-volume J2EE applications and salvaging failing projects, as well as intimate knowledge of the J2EE specifications.

I’ll help you to solve common problems with J2EE and avoid the expensive mistakes often made in J2EE projects. I will guide you through the complexity of the J2EE services and APIs to enable you to build the simplest possible solution, on time and on budget. I take a practical, pragmatic approach, questioning J2EE orthodoxy where it has failed to deliver results in practice and instead suggesting effective, proven approaches.

«I just wish this book had been around earlier when I was starting enterprise Java development. This book shows the benefits and pitfalls of J2EE and how best to avoid them.»
—Andrew J. Smith, Java Architect

«Rod’s depth and breadth of experience is quite impressive! J2EE developers can avoid many of the hard lessons Rod learned by reading this book.»
—Todd Lauinger, Software Construction Fellow, Best Buy, Inc.

It does not just discuss technology, but stress its practical application. The book is driven from the need to solve common tasks, rather than by the elements of J2EE.

It discuss risks in J2EE development
It takes the reader through the entire design, development and build process of a non-trivial application. This wouldn’t be compressed into one or two chapters, like the Java Pet Store, but would be a realistic example comparable to the complexity of applications readers would need to build
At each point in the design, alternative choices would be discussed. This would be important both where there’s a real problem with the obvious alternative, and where the obvious alternatives are perhaps equally valid
It emphasizes the use of OO design and design patterns in J2EE, without becoming a theoretical book —This text refers to an out of print or unavailable edition of this title.
