The Java EE 5 Tutorial, 3/e
暫譯: Java EE 5 教學手冊 (第三版)

Description

The Java EE 5 Tutorial is an introduction to programming server-side Java applications. This book takes a task-oriented, example-driven approach to show you how to build applications for the Java EE 5 platform. This book also describes the features and functionalities available with NetBeans 5.5.

 

What's new in this edition? The author team have updated the existing chapters to reflect the changes to JSP, EJB, Servlets, and more. Also, the authors have added new chapters on the Sun Java System Application Server 9 as a deployment environment for server-side technologies. The web-tier technology chapters cover the components used in developing the presentation layer of a Java EE 5 or stand-alone web application. The web services technology chapters cover the APIs used in developing standard web services. The Enterprise JavaBeans (EJB) technology chapters cover the components used in developing the business logic of a Java EE 5 application. The Persistence technology chapters cover the Java Persistence API, which is used for accessing databases from Java EE applications. The platform services chapters cover the system services used by all the Java EE 5 component technologies
