Java EE 8 Development with Eclipse - Third Edition

By: Ram Kulkarni

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.

JavaServer Faces


When working with JSP, we saw that it is not a good idea to mix scriptlets with the HTML markup. We solved this problem by using JavaBean. JavaServer Faces takes this design further. In addition to supporting JavaBeans, JSF provides built-in tags for HTML user controls, which are context aware, can perform validation, and can preserve the state between requests. We will now create the login application using JSF:

  1. Create a dynamic web application in Eclipse; let's name it LoginJSFApp. In the last page of the wizard, make sure that you check the Generate web.xml deployment descriptor box.
  2. Download JSF libraries from https://maven.java.net/content/repositories/releases/org/glassfish/javax.faces/2.2.9/javax.faces-2.2.9.jar and copy them to the WEB-INF/lib folder in your project.
  3. JSF follows the MVC pattern. In the MVC pattern, the code to generate user interface (view) is separate from the container of the data (model). The controller acts as the interface between the view and...
