Our in-depth guides focus on specific areas of the framework, such as Views, the Core framework, and Third-party Extensions.
We started work on a new User Guide, that should simplify learning process. Please feel free to contribute!
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. For a complete list of bundled and third-party plugins, visit the Plugin Registry..Bundled Plugins
