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

GlassFish domains


Alert readers might have noticed that theautodeploydirectory is under adomains/domain1subdirectory. GlassFish has a concept ofdomains. Domains allow a collection of related applications to be deployed together. Several domains can be started concurrently. GlassFish domains behave like individual GlassFish instances, a default domain called domain1 is created when installing GlassFish.

Creating domains

Additional domains can be created from the command line by issuing the following command:

asadmin create-domain domainname

The preceding command takes several parameters to specify ports where the domain will listen for several services (HTTP, Admin, JMS, IIOP, secure HTTP, and so on); type the following command in the command line to see its parameters:

asadmin create-domain --help

If we want several domains to execute concurrently on the same server, these ports must be chosen carefully since specifying the same ports for different services (or even the same service across domains...
