TheGlassFish OSE Server release notes are available by clicking this link: GlassFish Open Source Server, Release Notes (PDF). You should read this document as well as any late-breaking updates, on this page. You will find additional information by browsing to: GlassFish 5 Product Documentation and User Guides. Visit the Java EE 8 SDK Downloads page for more information about each distribution. See the Java EE 8 SDK Installation Instructions for installation information.

GlassFish is the Reference Implementation for Java EE. Java EE 8 introduces the JSON Binding API (JSON-B) for mapping between JSON text and Java objects, building on the JSON Processing API (JSON-P). Servlet has been enhanced with the additional support for HTTP/2 protocol. JAX-RS adds support for server-sent events and, building on concurrency facilities added in Java SE 8, a reactive client API. The new Java EE Security API provides enhanced support for authentication and authorization in web modules, and also introduces APIs for access to identity stores. Bean Validation is updated to reflect enhancements made in Java SE 8 and to extend the range of validated objects.

All of Java EE component projects are now hosted at GitHub. You will find the GlassFish Open Source Project at it's new home: javaee.github.io/glassfish. You will find a table, listing the locations and web-pages for all the Java EE component projects by browsing to javaee.github.io.

GlassFish Server Open Source Edition provides a server for the development and deployment of Java EE applications and web technologies. The Java EE 8 SDK bundles include GlassFish Server Open Source Edition 5.0 distributions. Those distributions implement Java EE 8 technologies.

Java EE 8 carries forwards the concept of profiles. A profile is a collection of Java EE technologies and APIs that address specific developer communities and application types. The following profiles are implemented through the GlassFish Server distributions:

Quick Start Guide (PDF) helps you become familiar with GlassFish Server Open Source Edition and explains how to perform basic tasks such as starting the server, accessing the Administration Console, and deploying a sample application. The guide pertains to both GlassFish Server Open Source Edition and GlassFish Server Open Source Edition Web Profile.

GlassFish Server Open Source Edition 5.0 Release Notes (PDF) provide the latest information about GlassFish Server Open Source Edition, including what's new, known issues, and pointers to additional resources.

Ensure that the required JDK software is installed on your system and that the JAVA_HOME environment variable points to the JDK installation directory, not the Java Runtime Environment (JRE) software.

Sample code in the Java EE Samples has been provided to assist developers in understanding Java functionality. This code has been deliberately simplified and does not take security considerations into account.
