Apache Excalibur v.2.2.3

Apache Excalibur 2.2.3 comes to users as a versatile and helpful open source software project of The Apache Software Foundation. The primary product is a lightweight, embeddable Inversion of Controlcontainer named Fortress that is written in java. Inversion of control, also known as the hollywood principle, is a simple but powerful concept. The idea is that vendors don't "wire up" all the pieces that make up an application (the "components") by writing lots of this-component-uses-that-one-like-so code, nor do use some kind of lookup directory (like JNDI, for example) where each component decides what components to interact with itself. Instead, instruct a smart piece of software, the container, to tell the components how to interact. Major Features: Good code. Code that comes from the mature avalon project (everything that used to be branded as "Avalon Excalibur" and "Avalon Fortress"). This includes two lightweight Inversion of Control containers. One of these powers, among other things, Cocoon. The other ("fortress") is the basis of projects like Keel. Excalibur also includes powerful and mature reusable "components" and "libraries", handling tasks ranging from thread management to component pooling to (URI-and-similar-) source resolving.Smart developers. Most of these people are or have been active in the avalon project in various roles. Several of them are apache members. Together they have loads and loads experience under their belts related to inversion of control development. In fact, I'm confident to say this list includes some of the biggest experts on inversion-of-control-style container development.Exciting community. Several open source and commercial projects (both at apache and elsewhere) depend on and contribute to the excalibur project. A strong team of enthusiastic developers (with strong ties to several other projects in the same problem domain) has various big and small plans with excalibur. One of the leading open source organiszations in the world, The Apache Software Foundation, is hosting the project, providing insight, advice, infrastructure, legal backing, a time- and battle-proven development process, and much more.
