Hi=20
=20
I created a code based on the WebWork code that can invoke a Struts 2 =
Action
from DWR. You can invoke it just like the WebWork version and you can =
use
DWRActionUtil.js. It does not do everything that the WebWorks code does, =
it
invokes de Action method and returns the Action object. Hope somebody =
finds
it useful.

public class DWRAction
{
  private static final Logger log =3D Logger.getLogger =
(DWRAction.class);
   =20
  public static Object execute (ActionDefinition actionDefinition, Map
params, HttpServletRequest request, HttpServletResponse response,
ServletContext servletContext) throws Exception {
    ActionMapping             mapping;
    Dispatcher                dispatcher;
    Map                       context;
    ActionProxy               proxy;
=20
    try
    {
      dispatcher =3D Dispatcher.getInstance ();
      mapping    =3D new ActionMapping (actionDefinition.getAction(),
actionDefinition.getNamespace(), actionDefinition.getMethod(), params);
      context    =3D dispatcher.createContextMap (request, response, =
mapping,
servletContext);
=20
      proxy      =3D ((ActionProxyFactory) dispatcher.getContainer
().getInstance (ActionProxyFactory.class)).createActionProxy
(actionDefinition.getNamespace (), actionDefinition.getAction (), =
context,
false, false);
      proxy.setMethod (actionDefinition.getMethod ());
      proxy.execute   ();
=20
      return (proxy.getAction ());
    }
    catch (Exception e)
    {
      log.error ("Cannot invoke action '" + actionDefinition.getAction() =
+
"' in namespace '" + actionDefinition.getNamespace() + "'", e);
      throw e;
    }
  }
}
