The Java EE 6 Tutorial

Preface

This tutorial is a guide to developing enterprise applications for the Java Platform, Enterprise Edition 6 (Java EE 6) using GlassFish Server Open Source Edition.

Oracle GlassFish Server, a Java EE compatible application server, is based on GlassFish Server Open Source Edition, the leading open-source and open-community platform for building and deploying next-generation applications and services. GlassFish Server Open Source Edition, developed by the GlassFish project open-source community at https://glassfish.dev.java.net/, is the first compatible implementation of the Java EE 6 platform specification. This lightweight, flexible, and open-source application server enables organizations not only to leverage the new capabilities introduced within the Java EE 6 specification, but also to add to their existing capabilities through a faster and more streamlined development and deployment cycle. Oracle GlassFish Server, the product version, and GlassFish Server Open Source Edition, the open-source version, are hereafter referred to as GlassFish Server.

The following topics are addressed here:

Before You Read This Book

Before proceeding with this tutorial, you should have a good knowledge of the Java programming language. A good way to get to that point is to work through The Java Tutorial, Fourth Edition, Sharon Zakhour et al. (Addison-Wesley, 2006).

Oracle GlassFish Server Documentation Set

The GlassFish Server documentation set describes deployment planning and system installation. The Uniform Resource Locator (URL) for GlassFish Server documentation is http://docs.sun.com/coll/1343.13. For an introduction to GlassFish Server, refer to the books in the order in which they are listed in the following table.

Table P–1 Books in the GlassFish Server Documentation Set


Book Title	Description
Release Notes	Provides late-breaking information about the software and the documentation and includes a comprehensive, table-based summary of the supported hardware, operating system, Java Development Kit (JDK), and database drivers.
Quick Start Guide	Explains how to get started with the GlassFish Server product.
Installation Guide	Explains how to install the software and its components.
Upgrade Guide	Explains how to upgrade to the latest version of GlassFish Server. This guide also describes differences between adjacent product releases and configuration options that can result in incompatibility with the product specifications.
Administration Guide	Explains how to configure, monitor, and manage GlassFish Server subsystems and components from the command line by using the asadmin(1M) utility. Instructions for performing these tasks from the Administration Console are provided in the Administration Console online help.
Application Deployment Guide	Explains how to assemble and deploy applications to the GlassFish Server and provides information about deployment descriptors.
Your First Cup: An Introduction to the Java EE Platform	For beginning Java EE programmers, provides a short tutorial that explains the entire process for developing a simple enterprise application. The sample application is a web application that consists of a component that is based on the Enterprise JavaBeans specification, a JAX-RS web service, and a JavaServer Faces component for the web front end.
Application Development Guide	Explains how to create and implement Java Platform, Enterprise Edition (Java EE platform) applications that are intended to run on the GlassFish Server. These applications follow the open Java standards model for Java EE components and application programmer interfaces (APIs). This guide provides information about developer tools, security, and debugging.
Add-On Component Development Guide	Explains how to use published interfaces of GlassFish Server to develop add-on components for GlassFish Server. This document explains how to perform only those tasks that ensure that the add-on component is suitable for GlassFish Server.
Embedded Server Guide	Explains how to run applications in embedded GlassFish Server and to develop applications in which GlassFish Server is embedded.
Scripting Framework Guide	Explains how to develop scripting applications in such languages as Ruby on Rails and Groovy on Grails for deployment to GlassFish Server.
Troubleshooting Guide	Describes common problems that you might encounter when using GlassFish Server and explains how to solve them.
Error Message Reference	Describes error messages that you might encounter when using GlassFish Server.
Reference Manual	Provides reference information in man page format for GlassFish Server administration commands, utility commands, and related concepts.
Domain File Format Reference	Describes the format of the GlassFish Server configuration file, `domain.xml`.
Java EE 6 Tutorial	Explains how to use Java EE 6 platform technologies and APIs to develop Java EE applications.
Message Queue Release Notes	Describes new features, compatibility issues, and existing bugs for GlassFish Message Queue.
Message Queue Administration Guide	Explains how to set up and manage a Message Queue messaging system.
Message Queue Developer’s Guide for JMX Clients	Describes the application programming interface in Message Queue for programmatically configuring and monitoring Message Queue resources in conformance with the Java Management Extensions (JMX).
