Java EE 7 First Look

Overview of this book

For several years, the development of robust, scalable, and secured applications was a headache for software companies. They had to use proprietary solutions with non-standard methods. With Java EE, many of these solutions have been standardized, simplified, adapted to the needs of the developer, and made freely available to the community. Thus, it is now possible to develop truly robust, secure, and scalable applications at a lower cost using tools such as: Eclipse, NetBeans, and GlassFish.Java EE 7 First Look is a practical guide which, through the creation of an online pre-registration website, will introduce you to the novelties of Java EE 7 and give you ideas for utilizing them.Giving you an insight on new features introduced in Java EE 7, this book begins with the objectives of Java EE 7 and then covers the new specifications added in Java EE 7. Next, you will move on to the improvements made in APIs and EJBs and how to work with them. You will also learn how to ensure that the quality of data is maintained that has been manipulated by your application and gives you the opportunity to put a small part of AOP (Aspect Oriented Programming) in action.Finally, the book will give you some ideas to realize n-tier applications using the Java EE platform and will also provide some guidance for the integration of your Java EE application to heterogeneous systems with which your application will interact.After reading Java EE 7 First Look, you'll have a good idea about the changes brought in by Java EE 7, as well as how to make the best use of these to build a large-scale application.

The Java API for JSON Processing 1.0 was developed under JSR 353. This section gives you only an overview of the API. The complete document specification (for more information) can be downloaded from

What is JSON?

JavaScript Object Notation (JSON) is a lightweight data-interchange text format. It is based on a subset of JavaScript, but it is completely language independent. JSON format is often used for data exchanges between web client and web server or web service. But, it can be used whenever you need to store or transmit relatively small amounts of data that can easily be represented as a combination of name-value pairs.

JSON is built on two structures, which are: a collection of name-value pairs and an ordered list of values. These structures are made from three data types: object, array, and value.


An object is an unordered set of name:value pairs within braces ({}). After each name...
