Building RESTful Web Services with Java EE 8

By: Mario-Leander Reimer

Overview of this book

Java Enterprise Edition is one of the leading application programming platforms for enterprise Java development. With Java EE 8 finally released and the first application servers now available, it is time to take a closer look at how to develop modern and lightweight web services with the latest API additions and improvements. Building RESTful Web Services with Java EE 8 is a comprehensive guide that will show you how to develop state-of-the-art RESTful web services with the latest Java EE 8 APIs. You will begin with an overview of Java EE 8 and the latest API additions and improvements. You will then delve into the details of implementing synchronous RESTful web services and clients with JAX-RS. Next up, you will learn about the specifics of data binding and content marshalling using the JSON-B 1.0 and JSON-P 1.1 APIs. This book also guides you in leveraging the power of asynchronous APIs on the server and client side, and you will learn to use server-sent events (SSEs) for push communication. The final section covers advanced web service topics such as validation, JWT security, and diagnosability. By the end of this book, you will have implemented several working web services and have a thorough understanding of the Java EE 8 APIs required for lightweight web service development.

Using Server-Sent Events (SSEs)

In this chapter, we're going to take a look at Server-Sent Events (SSE). We will have a look at the characteristics of some usage scenarios, and then we'll be implementing and sending simple SSEs on the server side using JAX-RS. Next up, we'll be implementing SSEs on the client-side using JAX-RS engine HTML and finally, we will have a look at sending and receiving server-sent broadcast events to implement something like a simple HTML chat client.

This chapter includes the following sections:

  • What are SSEs?
  • Implementing SSE on the server-side
  • Implementing SSE REST clients
  • Implementing and sending SSE broadcasts
