DESCRIPTION
The Digester component of Jakarta Commons makes it easy to read and parse configuration files and initialize system objects. It acts as an XML to Java object mapping tool that fires rules when matching patterns in the configuration file are encountered. Even though it is a very feature rich component, its architecture is such that plugging in your own set of rules is a breeze.
To understand Digester, it is important to understand the Digester Stack. Consequently, this module starts with a description of this particular entity in clear layman terms. It then shows how Digester does it matching business, and provides examples and description of the pre-built matching rules. The rules are many, and they are divided into relevant categories based on what they do. This module then shows you how to create and apply your own rules. There are several examples of Digester best practices, including externalizing rule and pattern sets, namespace aware parsing and sharing rules.
