Plugin Developers Guide

Apache Struts 2 provides a simple plugin architecture so that developers can extend the framework just by adding a JAR to the application’s classpath. Since plugins are contained in a JAR, they are easy to share with others. Several plugins are bundled with the framework, and others are available from third-party sources.
