Guides
Our in-depth guides focus on specific areas of the framework, such as Views, the Core framework, and Third-party Extensions.
Core Developers Guide
In processing a request, the framework utilizes three key class types: Actions, Interceptors, and Results, which are configured using one or more XML documents (or Java 5 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.Bundled Plugins
