Java EE 8 Application Development

Overview of this book

Java EE is an Enterprise Java standard. Applications written to comply with the Java EE specification do not tie developers to a specific vendor; instead they can be deployed to any Java EE compliant application server. With this book, you’ll get all the tools and techniques you need to build robust and scalable applications in Java EE 8. This book covers all the major Java EE 8 APIs including JSF 2.3, Enterprise JavaBeans (EJB) 3.2, Contexts and Dependency Injection (CDI) 2.0, the Java API for WebSockets, JAX-RS 2.1, Servlet 4.0, and more. The book begins by introducing you to Java EE 8 application development and goes on to cover all the major Java EE 8 APIs. It goes beyond the basics to develop Java EE applications that can be deployed to any Java EE 8 compliant application server. It also introduces advanced topics such as JSON-P and JSON-B, the Java APIs for JSON processing, and the Java API for JSON binding. These topics dive deep, explaining how the two APIs (the Model API and the Streaming API) are used to process JSON data. Moving on, we cover additional Java EE APIs, such as the Java API for Websocket and the Java Message Service (JMS), which allows loosely coupled, asynchronous communication. Further on, you’ll discover ways to secure Java EE applications by taking advantage of the new Java EE Security API. Finally, you’ll learn more about the RESTful web service development using the latest JAX-RS 2.1 specification. You’ll also get to know techniques to develop cloud-ready microservices in Java EE.

Preface

Java EE, J2EE, and the Spring framework


Java EE was introduced back in 2006; the first version of Java EE was Java EE 5. Java EE replaced J2EE; the last version of J2EE was J2EE 1.4, released back in 2003. Even though J2EE can be considered a dead technology, replaced by Java EE over 11 years ago, the term J2EE refuses to die. Many individuals to this day still refer to Java EE as J2EE; many companies advertise on their websites and job boards that they are looking for "J2EE developers", seemingly unaware that they are referring to a technology that has been dead for several years. The correct term is and has been for a long time, Java EE.

Additionally, the term J2EE has become a "catch-all" term for any server-side Java technology; frequently Spring applications are referred to as J2EE applications. Spring is not, and has never been, J2EE; as a matter of fact, Spring was created by Rod Johnson as an alternative to J2EE back in 2002. Just like with Java EE, Spring applications are frequently erroneously referred to as J2EE applications.
