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.

Chapter 1. What's New in Java EE 7

Because of their use, distributed applications require some non functional services such as remote access, security, transaction management, concurrency, and robustness, among others. Unless you have APIs that offer these types of services, you need to implement them all from scratch and therefore, increase the number of bugs, reduce software quality, and increase production costs and time. The Java EE platform was set up to save the developer from these concerns. It is made up of a set of APIs that facilitate the development and deployment of distributed, robust, scalable, and interoperable applications.

Since its first release in 1999, the Java EE platform has evolved over time by offering a newer, richer, and simpler version than the previous one. In order for you to have an overview of the improvements in Java EE 7, this chapter addresses the following topics:

  • A brief history of Java EE

  • The main goals of Java EE 7

  • Novelties of Java EE 7
