Oracle GlassFish Server is the world's first implementation of the Java Platform, Enterprise Edition (Java EE) 6 specification. Built using the GlassFish Server Open Source Edition, Oracle GlassFish Server delivers a flexible, lightweight and production-ready Java EE 6 platform.
Oracle GlassFish Server is based on the Java EE 6 Reference Implementation and is the first application server to support the full Java EE 6 platform and the new Java EE 6 Web Profile, which is designed specifically for Web applications. Oracle GlassFish Server delivers a new, efficient model for developing and deploying production-level applications. Developers can begin with just the Web Profile and grow to the full Java EE 6 platform when needed. Because Oracle GlassFish Server runs on the OSGi runtime, modular features can be added as necessary. Developers can also create hybrid applications - using OSGi services from Java EE Applications or using Java EE services from OSGi services. It also keeps the footprint as small as possible by loading only modules required to service deployed applications, improving startup time and reducing resource utilization.
Because it is swift and resource-efficient, the Oracle GlassFish server is the preferred middle-ware for mission-critical IT infrastructures where performance and prompt delivery of services to end-users is of utmost importance. In such environments, if the service level guarantees of the GlassFish server are not fulfilled, it is sure to result in dissatisfied users, severe penalties, and loss of revenue and reputation. You hence need to continuously monitor the performance of the GlassFish server, so that service level slippages are minimized and user satisfaction with the overlying business services is maximized. This is where eG Enterprise helps administrators to fulfill their duty in this regard.
