Description

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.
