内容简介

Get up to speed on the principal technologies in the Java Platform, Enterprise Edition 7, and learn how the latest version embraces HTML5, focuses on higher productivity, and provides functionality to meet enterprise demands. Written by Arun Gupta, a key member of the Java EE team, this book provides a chapter-by-chapter survey of several Java EE 7 specifications, including WebSockets, Batch Processing, RESTful Web Services, and Java Message Service.

You’ll also get self-paced instructions for building an end-to-end application with many of the technologies described in the book, which will help you understand the design patterns vital to Java EE development.

Understand the key components of the Java EE platform, with easy-to-understand explanations and extensive code samples

Examine all the new components that have been added to Java EE 7 platform, such as WebSockets, JSON, Batch, and Concurrency

Learn about RESTful Web Services, SOAP XML-based messaging protocol, and Java Message Service

Explore Enterprise JavaBeans, Contexts and Dependency Injection, and the Java Persistence API

Discover how different components were updated from Java EE 6 to Java EE 7
