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


Good support for debugging from language runtime and IDE can considerably reduce the time spent in debugging. Java runtime and Eclipse provide excellent support for debugging local and remote applications. To debug a remote application, launch it with debug parameters for JVM and connect the Eclipse debugger to it. You can then debug the remote application just as you would debug the local one, that is, set breakpoints, perform step operations, and inspect variables. You can also change variable values in the application when its execution is suspended.

In the next chapter, we will see how to develop JEE applications using EJBs and use the GlassFish server. Although this chapter explained the debugging of JEE applications deployed in Tomcat, you can use the same techniques in the GlassFish server.
