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.

<web-app>  
  <display-name>Struts 2 Webapp</display-name>  
  
  <context-param>  
    <param-name>webapp-composer-class</param-name>  
    <param-value>org.picocontainer.web.sample.ExampleStruts2Composer</param-value>  
  </context-param>

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.
