Advanced Java EE Development with WildFly

By: Deepak Vohra

Overview of this book

<p>This book starts with an introduction to EJB 3 and how to set up the environment, including the configuration of a MySQL database for use with WildFly. We will then develop object-relational mapping with Hibernate 4, build and package the application with Maven, and then deploy it in&nbsp;WildFly 8.1, followed by a demonstration of the use of Facelets in a web application.</p> <p>Moving on from that, we will create an Ajax application in the Eclipse IDE, compile and package it using Maven, and run the web application on WildFly 8.1 with a MySQL database. In the final leg of this book, we will discuss support for generating and parsing JSON with WildFly 8.1.</p>

Chapter 1. Getting Started with EJB 3.x

The objective of the EJB 3.x specification is to simplify its development by improving the EJB architecture. This simplification is achieved by providing metadata annotations to replace XML configuration. It also provides default configuration values by making entity and session beans POJOs (Plain Old Java Objects) and by making component and home interfaces redundant. The EJB 2.x entity beans is replaced with EJB 3.x entities. EJB 3.0 also introduced the Java Persistence API (JPA) for object-relational mapping of Java objects.

WildFly 8.x supports EJB 3.2 and the JPA 2.1 specifications from Java EE 7. While EJB 3.2 is supported, the sample application in this chapter does not make use of the new features of EJB 3.2 (such as the new TimerService API and the ability to disable passivation of stateful session beans). The sample application is based on Java EE 6 and EJB 3.1. The configuration of EJB 3.x with Java EE 7 is also discussed, and the sample application can be used or modified to run on a Java EE 7 project. We have used a Hibernate 4.3 persistence provider. Unlike some of the other persistence providers, the Hibernate persistence provider supports automatic generation of relational database tables, including the joining of tables.

In this chapter, we will create an EJB 3.x project and build and deploy this project to WildFly 8.1 using Maven. This chapter has the following sections:

  • Setting up the environment

  • Creating a WildFly runtime

  • Creating a Java EE project

  • Configuring a data source with MySQL database

  • Creating entities

  • Creating a JPA persistence configuration file

  • Creating a Session Bean Facade

  • Creating a JSP client

  • Configuring the jboss-ejb3-ejb subproject

  • Configuring the jboss-ejb3-web subproject

  • Configuring the jboss-ejb3-ear subproject

  • Deploying the EAR Module

  • Running the JSP Client

  • Configuring a Java EE 7 Maven Project
