Struts provides a J2EE framework for building Web applications. It is based on a Model 2 approach, a variant of MVC.
The original author of Struts is Craig McClanahan that now is working on the specification of JSF.
Struts2 is a major release of Struts, and incorporates many elements of WebWork. This version is different enough that it has its own project page, Struts2.
Struts is supported by a number of companies, including SourceLabs.
