> In WebWorks there is a DWR and Struts 2 Integration using the DWRAction class where yo can invoke the Action methods using DWR. I implemented a similar class, but not with all the functionality with Struts 2. I've done a project with this integration and it works really great.
> public class DWRAction
> {
>   private static final Logger log = Logger.getLogger (DWRAction.class);
>     
>   public static Object execute (ActionDefinition actionDefinition, Map params, HttpServletRequest request, HttpServletResponse response, ServletContext servletContext) throws Exception {
>     ActionMapping             mapping;
>     Dispatcher                dispatcher;
>     Map                       context;
>     ActionProxy               proxy;
>     try
>     {
>       dispatcher = Dispatcher.getInstance ();
>       mapping    = new ActionMapping (actionDefinition.getAction(), actionDefinition.getNamespace(), actionDefinition.getMethod(), params);
>       context    = dispatcher.createContextMap (request, response, mapping, servletContext);
>       proxy      = ((ActionProxyFactory) dispatcher.getContainer ().getInstance (ActionProxyFactory.class)).createActionProxy (actionDefinition.getNamespace (), actionDefinition.getAction (), context, false, false);
>       proxy.setMethod (actionDefinition.getMethod ());
>       proxy.execute   ();
>       return (proxy.getAction ());
>     }
>     catch (Exception e)
>     {
>       log.error ("Cannot invoke action '" + actionDefinition.getAction() + "' in namespace '" + actionDefinition.getNamespace() + "'", e);
>       throw e;
>     }
>   }
> }
> In this case I'm invoking the actions method and returning the action to the JSP page so I can access attributes that were set in the invocation. It would be nice to have something like this part of the Struts 2 standard. If you need help implemening this solution I would gladly help.
