Creating action URL with parameters using PortletStateManagerService

In the Using PortletStateManagerService for creating URLs from within the portlet blog i talked about how to create a URL to portal page from inside portlet.

But what if you want to create a action url pointing to portlet on particular page and you also want to send some parameters while calling the action, this will result in the processAction() method of the target method being called, you can use following method

private String getPortletActionURL(PortletRequest request,
      PortletResponse response) {
    PortletStateManager portletStateManager = null;
    try {
      portletStateManager = portletStateManagerService
          .getPortletStateManager(request, response);
      final URLFactory urlFct = portletStateManager.getURLFactory();
      final EngineURL url = urlFct.newURL(null);

      final SelectionAccessorFactory selectionAccessorFactory = portletStateManager
          .getAccessorFactory(SelectionAccessorFactory.class);
      SelectionAccessorController selectionAccessorCOntroller = selectionAccessorFactory
          .getSelectionController(url.getState());
      selectionAccessorCOntroller
          .setSelection("com.webspherenotes.popup.static");

      final PortletAccessorFactory portletFct = 
(PortletAccessorFactory) portletStateManager
          .getAccessorFactory(PortletAccessorFactory.class);
      final PortletAccessorController portletCtrl = 
portletFct
          .getPortletController("com.webspherenotes.popup.control",
              url.getState());
      portletCtrl.getParameters().put("userName",
          new String[] { "soloStateSample" });

    
      final PortletTargetAccessorFactory portletTargetAccessorFactory = 
(PortletTargetAccessorFactory)portletStateManager.getAccessorFactory(PortletTargetAccessorFactory.class);
      final PortletTargetAccessorController portletTargetAccessor = 
portletTargetAccessorFactory.getPortletTargetAccessorController(url.getState());

      portletTargetAccessor.setActionTarget("com.webspherenotes.popup.control");
      portletTargetAccessor.getParameters().put("actionParam", new String[]{"actionParamValue" });

      
      String finalURL = url.toString();
      System.out.println("Portal Page URL " + finalURL);
      return finalURL;
    } catch (InvalidConstantException e) {
      e.printStackTrace(System.out);
    } catch (CannotInsertSelectionNodeException e) {
      e.printStackTrace(System.out);
    } catch (CannotCloneDocumentModelException e) {
      e.printStackTrace(System.out);
    } catch (CannotCreateDocumentException e) {
      e.printStackTrace(System.out);
    } catch (StateNotInRequestException e) {
      e.printStackTrace(System.out);
    } catch (MissingUniqueNameException e) {
      e.printStackTrace(System.out);
    } catch (UnknownUniqueNameException e) {
      e.printStackTrace(System.out);
    } catch (StateManagerException e) {
      e.printStackTrace(System.out);
    } catch (UnknownAccessorTypeException e) {
      e.printStackTrace(System.out);
    } catch (CannotInstantiateAccessorException e) {
      e.printStackTrace(System.out);
    } catch (CannotInstantiateURLFactoryException e) {
      e.printStackTrace(System.out);
    }
    return null;
  }

You can use PortletTargetAccessor for creating action URLs pointing to particular portlet, it also allows you to set action parameters. This is how the target page looks like
