Programming Jakarta Struts, 2/e
暫譯: 編程 Jakarta Struts, 第二版

Description:

While the look and feel of an enterprise web application is certainly important, developers usually find themselves spending far too much time on the front-end presentation before they can get to coding the good stuff--the business logic at the heart of the program. Jakarta Struts addresses this issue by combining Java Servlets, Java ServerPages (JSP), custom tags, and messaging resources (like Java Message Service) into a unified, re-usable framework. The result is a cooperative, synergistic platform that's efficient and suitable for independent developers, large development teams, and everyone in between.

The Struts Framework has become a highly popular open source project, but there's still woefully little documentation on the technology. What does exist is far too basic and lacks critical information for developers like you writing today's complex web applications.

The revised and expanded Programming Jakarta Struts, 2nd Edition covers everything the successful earlier edition did--including an overview of the concepts involved in writing web applications; installation and configuration instructions for getting Struts up and running; a thorough discussion of how Struts implements the Model-View-Controller (MVC) design paradigm (known as the Model 2 approach) and how to interface with that pattern in your own applications; Logging, Validation, and Exception Handling with Struts; using Tiles; writing internationalization and localization code using Struts; and practical, real-world best practices for web applications--as well as plenty more: now fully up to date with Struts 1.1, this edition covers the latest material on tag libraries and the new JavaServerFaces (JSF) APIs and even includes all-new chapters on JSF, JSTL/EL, and security.

With each enterprise system he s developed, author Chuck Cavaness has spent many grueling hours learning invaluable lessons about Struts and figuring out the dos and the don'ts of building web applications. He saves you time and headaches by sharing that invaluable real-world experience here, with his realistic, practical, here's how to do it approach to using the Struts Framework to its fullest potential.
