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

The Customer database


Examples in this chapter will use a database called CUSTOMERDB. This database contains tables to track customer and order information for a fictitious store. The database uses JavaDB for its RDBMS, since it comes bundled with GlassFish, but it can be easily adapted to any other RDBMS.

A script is included with this book's code download to create this database and pre-populate some of its tables. Instructions on how to execute the script, and add a connection pool and data source to access it are included in the download as well.

The schema for the CUSTOMERDB database is depicted in the following diagram:

As can be seen in the diagram, the database contains tables to store customer information such as name, address, and email address. It also contains tables to store order and item information.

The ADDRESS_TYPES table will store values such as "Home", "Mailing", and "Shipping", to distinguish the type of address in the ADDRESSES table; similarly, the TELEPHONE_TYPES table...
