Our in-depth guides focus on specific areas of the framework, such as Views, the Core framework, and Third-party Extensions.

Core Developers Guide

Struts 2 processes requests using three core types: interceptors, actions, and results. Each may be configured via XML or annotations.

Tag Developers Guide

The framework offers a flexible view layer that supports multiple view technologies, including JSP, FreeMaker, and Velocity.

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.
