Custom event not firing

Hi BigRed - i did more testing.
Try this code - this will work. I went back to dependency injection to get session and it now works. Taken from this example: https://github.com/Adobe-Consulting-Services/acs-aem-samples/blob/master/bundle/src/main/java/com/ad...
I also see the event as Joerg points out.
@Component(metatype=true)
@Service
public class SimpleDSComponent implements Runnable,EventListener {
private Logger log = LoggerFactory.getLogger(this.getClass());
private BundleContext bundleContext;
@Reference
private SlingRepository repository;
//Inject a Sling ResourceResolverFactory
@Reference
private ResourceResolverFactory resolverFactory;
private Session session;
private ObservationManager observationManager;
//Inject a Sling ResourceResolverFactory to create a Session requited by the EventHandler
public void run() {
log.info("Running...");
}
//Place app logic here to define the AEM Custom Event Handler
protected void activate(ComponentContext ctx) {
this.bundleContext = ctx.getBundleContext();
try
{
//Invoke the adaptTo method to create a Session
// ResourceResolver resourceResolver = resolverFactory.getAdministrativeResourceResolver(null);
session = repository.loginAdministrative(null);
// Setup the event handler to respond to a new claim under content/claim....
observationManager = session.getWorkspace().getObservationManager();
final String[] types = { "nt:unstructured","sling:Folder" };
final String path = "/content/claim"; // define the path
observationManager.addEventListener(this, Event.NODE_ADDED, path, true, null, null, false);
log.info("Observing property changes to {} nodes under {}", Arrays.asList(types), path);
}
catch(Exception e)
{
e.printStackTrace();
}
}
protected void deactivate(ComponentContext componentContext) throws RepositoryException {
if(observationManager != null) {
observationManager.removeEventListener(this);
}
if (session != null) {
session.logout();
session = null;
}
}
//Define app logic that is fired when the event occurs - simply track the time
//when the event occurred.
public void onEvent(EventIterator itr) {
//Calendar cal = Calendar.getInstance();
//cal.getTime();
//SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss");
//log the time when the event occurred
log.info("A new node was added to content/claim ");
}
}

Can you elaborate more on this. It will help community to solve this...
I couldn't see errors in log file you shared.
I have a use for manipulating a property field on upload
was hoping to use this method instead of workflow route.
Simply just testing event article out before I make changes.
The article claims it's supposed to log a time/date when I create nt:unstructured or sling:folder
nodes under the /content/claim
Thanks.

Also try using this code too - replace the code in your OSGi bundle with this code... .
// Setup the event handler to respond to a new claim under content/claim....
observationManager = session.getWorkspace().getObservationManager();
final String[] types = { "nt:unstructured","sling:Folder" };
final String path = "/content/claim"; // define the path
observationManager.addEventListener(this, Event.NODE_ADDED, path, true, null, null, false);
log.info("Observing property changes to {} nodes under {}", Arrays.asList(types), path);
Okay this worked. Thanks Scott!
Now my problem is this seems to only fire once. I set timeout exception as well.
I need it to constantly watch over this folder to change some properties in crdxe.
Is this the wrong use case?
