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>

The library application


The library application is a simple, self-contained, real-life-based application that demonstrates HTML5 technologies such as WebSockets and shows how to use JAX-RS verbs, how to write data using JSON-P API, and how to take advantage of the asynchronous aspect of processing the resources. To stay on track the application contains the components that describe the preceding technologies using a simple GUI and does not have fancy dialog boxes or very complicated business logic.

How the application is deployed

The build system used for the sample application is Maven and the sample can be deployed in any Java EE 7-compatible application server, notably GlassFish v4.0, which is an open source reference implementation of Java EE specification.

The project's layout

The project's directory layout follows the standard Maven structure, which is briefly explained in the following table:
