## Overview{% #overview %}

GlassFish is the Eclipse implementation of Jakarta EE (formerly the reference implementation from Oracle) and supports Jakarta REST, Jakarta CDI, Jakarta Security, Jakarta Persistence, Jakarta Transactions, Jakarta Servlet, Jakarta Faces, Jakarta Messaging, and more. This allows developers to create enterprise applications that are portable and scalable, and that integrate with legacy technologies. The Glassfish integration allows users to monitor several different modules within Glassfish, such as applications, the HTTP service, the JMS service, JVM metrics, networking, and the transaction service.
