Resin 3.1.5 now contains a Struts2 ObjectFactory plugin, enabling Resin-IoC capabilities for any Struts2 action. Documentation is available at http://wiki.caucho.com/Struts2.

Resin-IoC capabilities for Struts2 actions

• WebBeans dependency injection with @In, @Named, etc.
• Scoped components including @SessionScoped, @RequestScoped, @ApplicationScoped
• EJB annotations like @TransactionAttribute
• Interception using @InterceptorType
• WebBeans event listening with @Observes

Adding the Object Factory

To enable Resin-IoC with Struts, you'll need to copy the resin/ext/resin-support.jar to either WEB-INF/lib or resin/ext-webapp. And you'll need to create or modify WEB-INF/classes/struts.properties as follows:

# Tell struts to ask Resin for new action instances
 struts.objectFactory = com.caucho.xwork2.ResinObjectFactory

Implementation details

public class ResinObjectFactory extends ObjectFactory {
    private WebBeansContainer _webBeans = WebBeansContainer.create();

   @Override
   public Object buildBean(Class clazz, Map extraContext)
   {
     return _webBeans.getObject(clazz);
   }
 }
