Apache Struts 2 is an elegant, extensible framework for building enterprise-ready Java web applications. Distributions of Struts 2 are available as a free download under the Apache License.
The contents of the Struts 2 documentation wiki (what you're reading now) are distributed with each release, but maintained via the on-line wiki.
We've started planning the next version of Struts aka Struts 3 (or 2.5) which will break backward compatibility, if you want to join please add your two cents here.
The documentation is grouped into four areas.
Our tutorials are designed to help you get started with the framework ASAP. We offer an all-purpose "Bootstrap" tutorial as well as specialty tutorials on portlets and database access.
Our in-depth technical guides focus on specific components of the framework, such as the Core framework, Struts Tags, and optional Extensions, as well as migrating from Struts 1 or WebWork 2.
Our FAQs and Cookbook examples provide a wide range of rapid-fire "HOWTOs" in question-and-answer format.
Our security bulletins explain any security issues and their solutions
Books, articles, and presentations about Struts 2.
The Struts 2 Community Wiki is an additional resource. It is not distributed with Struts 2, and contributions to the community wiki do not require a CLA.
