AEM 6.5: Events won't be fired
Hello,
I'm stuck at following situation:
I have a page and I want add some events to it. The content structure is
/content
/site
/mypage
/jcr:content
The node 'mypage' has the primary type 'cq:Page' and node 'jcr:content' the type 'cq:PageContent'.
To add events I created a service:
import org.apache.sling.api.resource.Resource;
import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.api.resource.ResourceResolverFactory;
import org.apache.sling.jcr.api.SlingRepository;
import org.apache.sling.settings.SlingSettingsService;
import org.osgi.service.component.annotations.*;
import javax.jcr.RepositoryException;
import javax.jcr.Session;
import javax.jcr.observation.Event;
import javax.jcr.observation.EventIterator;
import javax.jcr.observation.EventListener;
import java.util.*;
@Component(
service = MyServiceListener.class,
immediate= true)
public class MyServiceListener implements EventListener {
private SlingSettingsService settings;
private ResourceResolverFactory resourceResolverFactory;
private SlingRepository repository;
private ResourceResolver resolver;
private Session session = null;
protected void activate() {
try {
Map<String, Object> param = new HashMap<String, Object>();
param.put(ResourceResolverFactory.SUBSERVICE, "aserviceuser");
ResourceResolver resolver = null;
resolver = resourceResolverFactory.getServiceResourceResolver(param);
session = resolver.adaptTo(Session.class);
session.getWorkspace().getObservationManager().addEventListener(new TestOnEvent(),
Event.PROPERTY_CHANGED | Event.PROPERTY_ADDED | Event.PROPERTY_REMOVED, "/content/site/mypage/jcr:content", false, null, null, false);
} catch (Exception e) {
;
}
}
protected void deactivate() throws RepositoryException {
if (session != null) {
session.logout();
session = null;
}
}
}
Whenever the bundle is (re)started the above code works fine. So I added code for actions for defined events:
public void onEvent(EventIterator events)
{
try {
Map<String, Object> param = new HashMap<String, Object>();
param.put(ResourceResolverFactory.SUBSERVICE, "aserviceuser");
ResourceResolver resourceResolver = null;
resourceResolver = resourceResolverFactory.getServiceResourceResolver(param);
session = resourceResolver.adaptTo(Session.class);
while (events.hasNext()) {
...
}
} catch (Exception e) {
;
}
}
My Problem is, this piece of code won't always be executed. I could see his behaviour by adding output to logfiles and break points for the debug mode.
When some bundles are renewed then existing a good chance that above code will be executed. After that he won't be executed anymore.
My question: Where is my mistake?
Thanks in advanced
PS: The service user got all nessecary rights to read the content path.
