Overview of this book

JBoss Application Server meets high standards of reliability, efficiency, and robustness, and is used to build powerful and secure Java EE applications. It supports the most important areas of Java Enterprise programming including EJB 3.1, Contexts and Dependency Injection, JAX-WS and JAX-RS web services, the security framework, and more. Getting started with JBoss application server development can be challenging; however, with the right approach and guidance, you can easily master it and this book promises that.Written in an easy-to-read style, this book will take you from the basics of JBoss AS—such as installing core components and plugins—to the skills that will make you a JBoss developer to be reckoned with, covering advanced topics such as developing applications with the JBoss messaging service, JBoss web services, clustered applications, and more.You will learn the necessary steps to install a suitable environment for developing enterprise applications on JBoss AS. You will also learn how to design Enterprise applications using Eclipse, JBoss plugins, and Maven to build and deploy your applications. Readers will learn how to enable distributed communication using JMS. Storing and retrieving objects will be made easier using the Java Persistence API. The core section of the book will take you into the programming arena with tested, real-world examples. The example programs have been carefully crafted to be easy to understand and useful as starting points for your applications. This practical guide will show you how to gain hands-on experience rapidly on Java EE development using JBoss AS with easy-to-understand and practical programming examples.

Data persistence meets a standard


The arrival of an Enterprise Java Persistence standard based on the Plain Old Java Object (POJO) development model fills a substantial gap in the Java EE platform. The previous attempt (the EJB 2.x specification) missed the mark and created the stereotype of EJB entity beans being awkward to develop and too heavy for many applications. Therefore, it never achieved widespread adoption or general approval in many sectors of the industry.

Software developers knew what they wanted, but many could not find it in the existing standards, so they decided to look elsewhere. What they found was proprietary persistence frameworks, both in the commercial and open source domains.

In contrast to EJB 2.x Entity Beans, the EJB 3.0 Java Persistence API (JPA) is a metadata driven POJO technology. That is, to save data held in Java objects into a database, our objects are not required to implement an interface, extend a class, or fit into a framework pattern.
