design patterns are used in Struts?

Hi friends,

Struts is a open source java web application framwork. It is based on model 2 MVC (Model-View-Controller) architecture. Struts controller uses the command design pattern and the action classes use the adapter design pattern. The process() method of the RequestProcessor uses the template method design pattern.
