Input WCM content to Activity Stream Taskflow

Question

Hi I am trying to input the data coming from WCM to Activity Stream task flow. Plan is read the data from WCM using java API and input it to the activity stream task flow. Can some one tell me how can we access this taskflow using Java API. I went through the API ref but couldn't fig out how to use it. 
Thank in advance

Hi.
You can use WebCenter API. In case of version 11.1.1.8:http://docs.oracle.com/cd/E29542_01/apirefs.1111/e15995/oracle/webcenter/activitystreaming/package-summary.html
Take a look in the classes ActivityStreamingService and ActivityStreamingServiceFactory
Basically you have to use ActivityStreamingService for posting new updates. How?.
To get the ActivityStreamService:
ActivityStreamingService service = ActivityStreamingServiceFactory.getInstance().getActivityStreamingService();
Fill all parameters requited for method createActivityElement
applicationID - application ID of the activity:
WCApplicationFactory fact = FactoryFinder.getFactory(WCApplicationFactory.class.getCanonicalName());
WCApplication application = fact.getWCApplication();
String applicationID = application.getApplicationName();
scope - the Scope of the activity
ServiceContext.getContext().getScope()
serviceID - the service ID of the activity Depending of the content there are different serviceId:    
wiki = oracle.webcenter.wiki    
blog = oracle.webcenter.blog    
document = oracle.webcenter.doclib    
webContent = oracle.webcenter.content
You can use UCMHelper.getServiceID passing the resourceType as argument to calculate it or when retrieving the node with Content Presenter, using #{node.propertyMap['webcenter:serviceid'].value.stringValue} will retrieve corresponding serviceID directly.
activityType - type of the activity Take a look into the API to fill it
actors - list of actors involved in the activity (there must be at least one actor in the activity) Take a look into the API to fill it
objects - list of objects involved in the activity (optional) Take a look into the API to fill it
permission - the permission of the activity Take a look into the API to fill it
activityTime - time when the activity happens Take a look into the API to fill it
Sample taken from activity libraries. Remember replace all the sample variables with how to get ApplicationID, Current Scope, etc... that I share to you
ActivityStreamingService service = ActivityStreamingServiceFactory.getInstance().getActivityStreamingService();
      ActivityActor actor0 = service.createActor(this.actor0DisplayName.toLowerCase());
      ActivityActor actor1 = service.createActor(this.actor1DisplayName.toLowerCase());
      List actors = new ArrayList();
      if ((!this.actor0DisplayName.equals("")) || (!this.actor0DetailURL.equals("")))
        actors.add(actor0);
      if ((!this.actor1DisplayName.equals("")) || (!this.actor1DetailURL.equals("")))
        actors.add(actor1);
      ActivityObjectType objectType = ((JpaActivityStreamingService)service).createObjectType("message");
      ActivityObject object0 = service.createObject("object0", objectType, this.object0DisplayName);
      ActivityObject object1 = service.createObject("object1", objectType, this.object1DisplayName);
      List objects = new ArrayList();
      if ((!this.object0DisplayName.equals("")) || (!this.object0DetailURL.equals("")))
        objects.add(object0);
      if ((!this.object1DisplayName.equals("")) || (!this.object1DetailURL.equals("")))
        objects.add(object1);
      ActivityType activityType = ((JpaActivityStreamingService)service).createActivityType("test");
      activityType.setMessage(this.message);
      ActivityElement activity = service.createActivityElement("customapp", new Scope("test"), "oracle.webcenter.activitystreaming.test", activityType, actors, objects, ActivityPermission.SHARED, new Date());
      service.publish(activity);
    catch (ActivityException e)
      WCServiceViewUtils.getInstance().logAndDisplayError(e);
I hope it helps
