New in Java EE 8 SDK
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.
The Java EE SDK included new material in the Tutorial, as well as new Samples that will help you learn and use these new features.
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:
