• BSD-style license, which allows it to be modified for and embedded within commercial, closed source software (unlike the popular GPL and LGPL licenses)
• Modular GBean-based architecture, which allows users to remove unneeded services and build very lightweight configurations of the server
• Non-Profit ASF leadership, which provides legal protection, ensures stability across the loss of individual contributors and insulates the project from commercial conflicts of interest
• Diverse support community, in which companies compete freely and openly to provide services, with none enjoying any particular trademark advantage

Software consulting giant IBM has provided considerable support to the project through marketing, code contributions, and the funding of several project committers.

Open Source Projects

Like most other enterprise operating systems, Geronimo is built on a kernel -- a microkernel that lays the foundation for everything above it. Geronimo's kernel is J2EE agnostic. Its sole purpose is to manage Geronimo's building blocks. Geronimo is marked by a sleek architectural design which is based on the concept of Inversion of Control (IoC) (sometime called dependency injection), which means that the kernel has no direct dependency on any of its components. The kernel is a framework for services that controls the service life cycle and registry. The kernel is based on Java 2 Platform, Enterprise Edition (J2EE). It works with the services and components to build specific configurations -- one of which is a full J2EE stack. A majority of the Geronimo services are added and configured through GBeans to become a part of the overall application server. A GBean is the interface that connects the component to the kernel. Each GBean can maintain state, depend on, and interrelate with other GBeans, and operate on events from the kernel and other GBeans. It is possible to switch between two Web application servers, for example Jetty or Tomcat without affecting the whole architecture using a GBeans interface. Java 2 Platform, Enterprise Edition or J2EE is a Standard (albeit with no ISO or ECMA standard) for developing distributed Multi-tier architecture applications, based on modular components running on an application server. ... Inversion of Control is an important object-oriented programming principle that can be used to reduce coupling inherent in computer programs. ...

This flexible architecture helps Geronimo developers integrate several existing, field-tested open-source projects to meet their goal (not reinventing the wheel). Many of these projects are mature and well known.
