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.

Using messaging services for asynchronous communication

The message service, provided in Java EE by the Java Message Service (JMS) API, is one of the most important and versatile features provided by Java EE environments.

It uses the Producer-Consumer approach, where one peer (the Producer) puts a message into a queue and another peer (the Consumer) reads the message from there.

Both the Producer and Consumer can be different applications, even using different technologies.

This recipe will show you how to build a messaging service using GlassFish 5. Each Java EE server has its own way to set up the service, so if are using some other implementations, you should take a look at its documentation.

On the other hand, the Java EE code generated here will work on any Java EE 8-compatible implementation. Standard for the win!
