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

Summary


In this chapter, we covered how to set up JMS connection factories, JMS message queues, and JMS message topics in GlassFish, by using the GlassFish web console. We also covered how to send messages to a message queue via the javax.jms.JMSProducer interface. Additionally, we covered how to receive messages from a message queue via the javax.jms.JMSConsumer interface. We also covered how to asynchronously receive messages from a message queue by implementing the javax.jms.MessageListener interface and saw how to use the above interfaces to send and receive messages to and from a JMS message topic. We also looked at how to browse messages in a message queue without removing those messages from the queue via the javax.jms.QueueBrowser interface. Finally, we saw how to set up and interact with durable subscriptions to JMS topics.
