Preface
-------

This guide explains how to upgrade to GlassFish Server Open Source
Edition 4.0 from previous GlassFish Server and Sun GlassFish Enterprise
Server product releases. Also included in this guide are instructions
for upgrading configuration data and Java EE applications from
binary-compatible earlier versions of this software to work with
GlassFish Server Open Source Edition 4.0. Finally, this guide describes
compatibility issues that affect data and applications that are to be
migrated.

Note:

The main thrust of the GlassFish Server Open Source Edition 4.0 release
is to provide an application server for developers to explore and begin
exploiting the new and updated technologies in the Java EE 7 platform.
Thus, the upgrade feature of GlassFish Server was not a focus of this
release. The feature is included in the release, but it may not function
properly with some of the new features added in support of the Java EE 7
platform.

|=======================================================================


This preface contains information about and conventions for the entire
GlassFish Server Open Source Edition (GlassFish Server) documentation
set.

GlassFish Server 4.0 is developed through the GlassFish project
open-source community at `http://glassfish.java.net/`. The GlassFish
project provides a structured process for developing the GlassFish
Server platform that makes the new features of the Java EE platform
available faster, while maintaining the most important feature of Java
EE: compatibility. It enables Java developers to access the GlassFish
Server source code and to contribute to the development of the GlassFish
Server. The GlassFish project is designed to encourage communication
between Oracle engineers and the community.

(`http://docs.oracle.com/javaee/7/firstcup/doc/home.html`). For beginning
Java EE programmers, this short tutorial 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.
