== Preface

[NOTE]
====
This documentation is part of the Java Enterprise Edition contribution
to the Eclipse Foundation and is not intended for use in relation to
Java Enterprise Edition or Orace GlassFish. The documentation is in the
process of being revised to reflect the new Jakarta EE branding.
Additional changes will be made as requirements and procedures evolve
for Jakarta EE. Where applicable, references to Jakarta EE or Java
Enterprise Edition should be considered references to Jakarta EE.

Please see the Title page for additional license information.

This book demonstrates key features of the GlassFish Server product and
enables you to quickly learn the basics. Step-by-step procedures
introduce you to product features and enable you to use them
immediately.

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

GlassFish Server 7 is developed through the GlassFish project
open-source community at `https://github.com/eclipse-ee4j/glassfish`. The
GlassFish project provides a structured process for developing the
GlassFish Server platform that makes the new features of the Jakarta EE
platform available faster, while maintaining the most important feature
of Jakarta 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.
