Avalon Beginners Guide

Welcome to the Apache Avalon "Beginner's Guide."

The purpose of this guide is to ease Avalon's notorious learning curve. To some, the programming framework possesses the same mysterious atmosphere as its Arthurian namesake. This is truly unfortunate since Avalon, at its core, is profoundly simple. The sort of simple that when you "get it" you wonder what all the fuss was about.

One way to describe Avalon is as a set of design patterns -- programming methods and object oriented techniques -- and concrete implementations of those patterns. In this guide we will focus on the implementation and application side of the framework. In other words, real programming examples and real application solutions. Concepts like "component oriented programming" and "inversion of control" need not be esoteric and seeing actual usage of these ideas will help you see how Avalon can apply to and improve your own projects. If your exploration of Avalon is anything like my own, then you'll soon begin to wonder why you ever programmed any other way.

Enjoy!
