Java EE 8 Development with Eclipse - Third Edition

Overview of this book

Java EE is one of the most popular tools for enterprise application design and development. With recent changes to Java EE 8 specifications, Java EE application development has become a lot simpler with the new specifications, some of which compete with the existing specifications. This guide provides a complete overview of developing highly performant, robust and secure enterprise applications with Java EE with Eclipse. The book begins by exploring different Java EE technologies and how to use them (JSP, JSF, JPA, JDBC, EJB, and more), along with suitable technologies for different scenarios. You will learn how to set up the development environment for Java EE applications and understand Java EE specifications in detail, with an emphasis on examples. The book takes you through deployment of an application in Tomcat, GlassFish Servers, and also in the cloud. It goes beyond the basics and covers topics like debugging, testing, deployment, and securing your Java EE applications. You'll also get to know techniques to develop cloud-ready microservices in Java EE.

Creating JMS application using JSF and CDI beans


In this section, we will see how to create a JMS application using JSF and Component Dependency Injection (CDI) beans. With CDI beans, we can reduce the code that we wrote using JMS APIs, because we can use annotations to inject objects such as the JMS connection factory, queue, and topic. Once we obtain references to these objects, the steps to send or receive data are the same as those discussed in the previous section. Therefore, our examples in this section do not list the entire code. For the complete source code, download the source code for this chapter.

To prepare our project for using JSF, we need to create web.xml and add the JSF servlet definition and mapping in it. Right-click on the project and select the Java EE Tools | Generate Deployment Descriptor Stub option. This creates web.xml in the WebContent/WEB-INF folder. Add the following servlet definition and mapping (within the web-app tag) in web.xml:

  <servlet>
