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>

Event notification application


The Twitter-based application is the first sample application that will demonstrate a HTML5-based application developed on top of Server-sent Events, JAX-RS 2.0 API, Asynchronous Servlet, and the Twitter Search API together, to dynamically update a page with more search results periodically.

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, an open source reference implementation of the Java EE 7 specification.

Note

Apache Maven is a build management tool. More information about Maven can be found at http://maven.apache.org and more information about GlassFish can be found at https://glassfish.java.net/

The project's layout

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