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.

Putting it all together

The example that will allow us to put together most of the APIs already studied since the first chapter, is an online preregistration site. In this example, we will not write any code. We limit ourselves to the presentation of an analysis of a problem that will help you understand how to use each of the pieces of code that are used to illustrate points in this book, in order to make a quality application based on the latest functionality of Java EE 7.

Presenting the project

The virtual enterprise software technology has received from a private university the order for creating an application to manage the preregistration of students online (candidate registration, validation of applications, and notifications of different candidates) and provide a real-time chat room for connected students. Furthermore, for statistical purposes, the system will allow the ministry of education access to certain information from a heterogeneous application.

The system called ONPRINS must...
