Chapter 1, Getting Started with GlassFish, explains how to install and configure GlassFish. Deploying Java EE applications through the GlassFish web console are also explained. Finally, basic GlassFish administration tasks such as setting up domains and database connectivity by adding connection pools and data sources are discussed.

Chapter 2, JavaServer Faces, covers development of web applications using JSF, including new features such as HTML5-friendly markup and Faces Flows. It also covers how to validate user input using JSF's standard validators and also by creating our own custom validators or by writing validator methods.

Chapter 3, Object Relational Mapping with JPA, discusses how to develop code that interacts with a Relational Database Management System (RDBMS) such as Oracle or MySQL through the Java Persistence API.

Chapter 4, Enterprise JavaBeans, explains how to develop applications using both session and message-driven beans. Major EJB features such as transaction management, the EJB timer service, and security are covered. The life cycle of the different types of Enterprise JavaBeans are covered, including an explanation of how to have EJB methods automatically invoked by the EJB container at certain points in the life cycle.

Chapter 5, Contexts and Dependency Injection, provides an introduction to Contexts and Dependency Injection (CDI). The chapter covers CDI named beans, dependency injection using CDI, and CDI qualifiers.

Chapter 6, JSON Processing with JSON-P, covers how to generate and parse JavaScript Object Notation (JSON) data using the new JSON-P API. It also covers both APIs for processing JSON: the Model API and the Streaming API.

Chapter 7, WebSockets, explains how to develop web-based applications that feature full duplex communication between the browser and the server as opposed to relying on the traditional HTTP request/response cycle.

Chapter 8, The Java Message Service, covers how to set up JMS connection factories, JMS message queues, and JMS message topics in GlassFish using the GlassFish web console. The chapter also discusses how to develop messaging applications using the completely revamped JMS 2.0 API.

Chapter 9, Securing Java EE Applications, covers how to secure Java EE applications through provided security realms as well as how to add custom security realms.

Chapter 10, Web Services with JAX-WS, covers how to develop web services and web service clients via the JAX-WS API. Web service client code generation using ANT or Maven as a build tool has been explained.

Chapter 11, Developing RESTful Web Services with JAX-RS, discusses how to develop RESTful Web services via the Java API for RESTful Web services as well as how to develop RESTful Web service clients via the brand new standard JAX-RS client API. It also explains how to automatically convert data between Java and XML by taking advantage of the Java API for XML Binding (JAXB).

The following software needs to be installed to follow the material in this book:

This book assumes familiarity with the Java language. The target market for this book is the existing Java developers who wish to learn Java EE and the existing Java EE developers who wish to update their skills to the latest Java EE specification.

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The @Named class annotation designates this bean as a CDI named bean."

A block of code is set as follows:

if (!emailValidator.isValid(email)) {
  FacesMessage facesMessage = new FacesMessage(htmlInputText.
getLabel()
+ ": email format is not valid");
  throw new ValidatorException(facesMessage);
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

        <ejb>
            <ejb-name>CustomerDaoBean</ejb-name>
            <ior-security-config>
                <as-context>
                    <auth-method>username_password</auth-method>
                    <realm>file</realm>
                    <required>true</required>
                </as-context>
            </ior-security-config>
        </ejb>

Any command-line input or output is written as follows:

$ ~/GlassFish/glassfish4/bin $ ./asadmin start-domain
Waiting for domain1 to start ........

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Clicking on the Next button moves you to the next screen."
