= What is Avalon? =

Avalon is a component framework for Java (and effort is underway for other languages too).

''Ok, so what is a component framework?''

Component Oriented Programming (COP) combines nifty design patterns such as Inversion of Control
and Seperation of Concerns to traditional Object Oriented Programming.  Design patterns are
essentially 'best practices' for solving common programming problems.  COP applies these practices
to components -- reusable, replacable, composable objects which when assembled together (usually
inside of a container) make for a well designed, secure, and easily maintained application.

''That sounds cool, but kinda abstract and generic...''

In a way, yes.  Avalon is somewhat abstract and generic, just like object oriented programming
is abstract and generic.  Avalon is a COP framework for Java (and soon other languages!).
 All the basic algorithms and utilities for using those design patterns are in place.  There
are even a couple of containers and prebuilt components available.  You can then use Avalon
to build just about anything, from a web application to a new web framework, from a desktop
standalone app to a new application server.  Most of the 'extras' of Avalon are designed to
build server-like applications, but the framework itself can be used anywhere.
