Struts2

To configure PicoContainer to handle the dependency injection of Struts2 actions, refer to the web.xml below. For a start there is a slightly different listener to the one defined in the main page. Also, instead of using Struts2’s servlet, use ours. Everything else from the standard Struts2 setup is appropriate.

The Maven example project is here. Make sure you make and configure your own WebappComposer implementation. Note that we use a base class for Struts2 applications: Struts2Composer See downloads on how to download the struts2 module either using Maven or by downloading full distribution.
