[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 Java EE or Java 
Enterprise Edition should be considered references to Jakarta EE. 

Please see the Title page for additional license information.
========================================================================

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

GlassFish Server is developed through the GlassFish project open-source
community at `https://javaee.github.io/glassfish/`. 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.

The following tutorials explain how to develop Java EE applications:

* https://javaee.github.io/firstcup/[Your First Cup: An Introduction to
the Java EE Platform] (`https://javaee.github.io/firstcup/`). 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.
* https://javaee.github.io/tutorial/[The Java EE 8 Tutorial]
(`https://javaee.github.io/tutorial/`). This comprehensive tutorial
explains how to use Java EE 7 platform technologies and APIs to develop
Java EE applications.

Javadoc tool reference documentation for packages that are provided with
GlassFish Server is available as follows.

* The API specification for version 8 of Java EE is located at
`https://javaee.github.io/javaee-spec/javadocs/`.
