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.

Summary


EJBs are ideal for writing business logic in web applications. They can act as the perfect bridge between web interface components such as JSF, servlet, or JSP and data access objects such as JDO. EJBs can be distributed across multiple JEE application servers (this could improve application scalability), and their life cycle is managed by the container. EJBs can be easily injected into managed objects or can be looked up using JNDI.

Eclipse JEE makes creating and consuming EJBs very easy. Just like we saw how Tomcat can be configured and managed within Eclipse, JEE application servers, such as GlassFish, can also be managed from within Eclipse.

In the next chapter, we will learn how to create web applications using Spring MVC. Although Spring is not part of JEE, it is a popular framework to implement the MVC pattern in JEE web applications. Spring can also work with many of the JEE specifications.
