Expert One-on-One J2EE Design and Development

Summary

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.

What you will learn from this book

• When to use a distributed architecture
• When and how to use EJB
• How to develop an efficient data access strategy
• How to design a clean and maintainable web interface
• How to design J2EE applications for performance

"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.

摘要

在實際應用中，使用J2EE的結果往往令人失望 - 應用程序通常速度緩慢，過於複雜，並且開發時間過長。我認為問題不在於J2EE本身，而在於它經常被使用不當。許多J2EE出版物提倡的方法在理論上可能很好，但在實際中往往失敗，或者沒有提供真正的商業價值。

在這本書中，我提供了一個實用的指南，讓您可以在實際應用中使用J2EE。我借鑒了設計成功的高容量J2EE應用程序和挽救失敗項目的經驗，以及對J2EE規範的深入了解。

我將幫助您解決J2EE中的常見問題，避免在J2EE項目中犯下昂貴的錯誤。我將引導您通過J2EE服務和API的複雜性，使您能夠按時按預算構建最簡單的解決方案。我采取實用、務實的方法，對J2EE的正統觀點提出質疑，如果在實踐中未能產生結果，則建議有效的、經過驗證的方法。

您將從本書中學到什麼

• 何時使用分佈式架構
  


• 何時以及如何使用EJB
  


• 如何開發高效的數據訪問策略
  


• 如何設計乾淨且易於維護的網頁界面
  


• 如何為性能設計J2EE應用程序

“我只希望在我剛開始進行企業級Java開發時，這本書已經存在。這本書展示了J2EE的好處和陷阱，以及如何最好地避免它們。” - Andrew J. Smith，Java架構師

“Rod的經驗的深度和廣度令人印象深刻！通過閱讀這本書，J2EE開發人員可以避免Rod學到的許多艱難教訓。” - Todd Lauinger，軟件構建專家，Best Buy，Inc.
