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.

Chapter 4. Learning Context Dependency Injection

Chapter 3, Beginning Java EE 6 – EJBs, was a challenging chapter, since we had to cover lots of ground, including Java Enterprise enhancements and Maven-specific configuration. If you are still a Maven non-believer, in this chapter, we will give you one more chance to embrace this amazing framework.

This chapter discusses Contexts and Dependency Injection (CDI), which is a new addition to the Java EE specification as of Java EE 6. It provides several benefits that were missing to Java EE developers, such as allowing any JavaBean to be used as a JSF managed bean, including stateless and stateful session beans.

Some of the topics covered in this chapter include:

  • What is Context Dependency Injection and how it relates to EJB

  • How to rewrite our Ticket Booking example to use CDI and Java Server Faces technology

  • How to run the project using Maven

This chapter assumes familiarity with Java Server Faces (JSF), which will be used to provide a graphical...
