Overview of this book

<p>As the technology landscape moves focus towards smaller devices, the need for building scalable, flexible, lightweight, and real-time communications-based applications grows. HTML 5 and Java EE 7 provide a new synthesis of technologies that demonstrate tremendous scope and potential in areas of device independence, asynchronous communication, interoperability, and portability.<br /><br />Developing RESTful Services with JAX-RS 2.0, WebSockets, and JSON is a practical, hands-on guide that provides you with clear and pragmatic information to take advantage of the real power behind HTML5 and Java EE technologies. This book also gives you a good foundation for using them in your applications.<br /><br />Developing RESTful Services with JAX-RS 2.0, WebSockets, and JSON looks at the different HTML5-based Java EE 7 API, and takes a deep dive into the individual areas of technologies to cover basic to advanced concepts, and also provides best practices for each API. You will also learn how to build a REST-based Event Notification Application using the Twitter API, tying all the different technologies together that we will cover. You will also take a look at integrating different Java EE APIs to build a Library Application. If you want to take advantage of using the new HTML5 technologies and Java EE 7 platform, then this is the book for you. You will learn everything you need to know to build portable RESTful Web Services with JAX-RS 2.0, Web Sockets, JSON, and Server-Sent Events.</p>

Summary


In this chapter we looked at advanced topics for WebSockets and Server-sent Events. We demonstrated with code snippets how to use encoders and decoders and how to receive different kinds of data using WebSockets. We also demonstrated a sample that showed how WebSockets will work with SSL so that when working with proxy servers, the communication is encrypted.

We also discussed best practices for implementing Server-sent Events and WebSockets. We learned how to ensure messages are not lost in Server-sent Events by associating IDs with events. We covered the Jersey Client API for Server-sent Events.

In the next chapter, we will cover more advanced topics such as JSON API in Java EE and the aspects of asynchronous programming to improve scalability with respect to various Java EE specifications such as JAX-RS 2.0, EJB and Servlets.
