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.

A brief history of Java EE

Formerly called J2EE, the first version of Java EE platform was officially released in December 1999 with 10 specifications. Among these specifications, there were Servlets and JavaServer Pages (JSP) for data presentation, Enterprise JavaBeans (EJB) for the management of persistent data, remote access to business services through RMI-IIOP (Remote Method Invocation over Internet Inter-ORB Protocol), and the JMS (Java Message Service) specification, which was used to send messages.

Despite efforts and many contributions, early versions of Java EE were too complex and difficult to implement. This led to much criticism and caused the rise of competing frameworks such as Spring Framework.

Having drawn lessons from its previous failures, the platform has considerably evolved over time until the production of Java EE 5, which permitted the platform to regain its lost esteem. From this version, Java EE continues to provide easier, richer, and more powerful versions of the platform.

The preceding diagram gives an overview of the important changes made to Java EE platform since the release of the first version in December 1999. This diagram highlights the release dates, updates, and major improvements in each version. It also allows us to have an idea about the central theme behind each version.
