Overview of this book

Java EE is a collection of technologies and APIs to support Enterprise Application development. The choice of what to use and when can be dauntingly complex for any developer. This book will help you master this. Packed with easy to follow recipes, this is your guide to becoming productive with Java EE 8. You will begin by seeing the latest features of Java EE 8, including major Java EE 8 APIs and specifications such as JSF 2.3, and CDI 2.0, and what they mean for you. You will use the new features of Java EE 8 to implement web-based services for your client applications. You will then learn to process the Model and Streaming APIs using JSON-P and JSON-B and will learn to use the Java Lambdas support offered in JSON-P. There are more recipes to fine-tune your RESTful development, and you will learn about the Reactive enhancements offered by the JAX-RS 2.1 specification. Later on, you will learn about the role of multithreading in your enterprise applications and how to integrate them for transaction handling. This is followed by implementing microservices with Java EE and the advancements made by Java EE for cloud computing. The final set of recipes shows you how take advantage of the latest security features and authenticate your enterprise application. At the end of the book, the Appendix shows you how knowledge sharing can change your career and your life.

Building Java EE containers using Docker

Since day one, Java EE has been based on containers. If you doubt it, just have a look at this diagram:

Java EE architecture: https://docs.oracle.com/javaee/6/tutorial/doc/bnacj.html

It belongs to Oracle's official documentation for Java EE 6 and, actually, has been much the same architecture since the times of Sun.

If you pay attention, you will notice that there are different containers: a web container, an EJB container, and an application client container. In this architecture, it means that the applications developed with those APIs will rely on many features and services provided by the container.

When we take the Java EE application server and put it inside a Docker container, we are doing the same thing— it is relying on some of the features and services provided by the Docker environment.

This recipe will show you...
