Excalibur is a platform for component and container applications built on key design patterns such as Inversion of Control and
Separation of Concerns available for the Java platform. You can use Excalibur to build any number of other applications
from desktop centric Swing apps to complicated servers. The Avalon Framework (the core of Excalibur) is often used as the
"underpinning" of a larger application or platform. Such applications include Apache Cocoon, Apache James, and the Keel Framework.
Excalibur is not part of the J2EE stack. While Excalibur can be used in developing J2EE applications and even used to build
a J2EE server, the platform is not part of J2EE or a J2EE application server. Excalibur is much simpler and does not
include many J2EE specifications out of the box. That said, you might write a J2EE application which embeds Excalibur
(such as in a servlet) or you may embed a J2EE server in a larger Excalibur-based container.
The Excalibur platform is the following:
* A core framework for component programming (The Avalon Framework)
* An IoC container called Fortress
* A set of container utilities called ContainerKit
* A component library called Cornerstone
When working with Excalibur you may use one or all of these.
