Hello Marcel, > could you please enable debug level for the class > org.apache.jackrabbit.core.observation.ObservationManagerFactory and run > your code again? you will then see the full stacktrace of the exception > that is thrown. that will give us more insight which listener causes the > exception and where.
I had some problems with commons-logging but in the end (through some hard coding) got some output: [java] 2005-11-24 22:58:41,764 [ObservationManager] DEBUG org.apache.jackrabbit.core.observation.ObservationManagerFactory - event delivery to 4 consumers started... [java] received events: [java] Event[path=/sample node/jcr:primaryType|type=4|userID=bogus] [java] Event[path=/sample node/sample property|type=4|userID=bogus] [java] Event[path=/sample node|type=1|userID=bogus] [java] 2005-11-24 22:58:41,764 [ObservationManager] WARN org.apache.jackrabbit.core.observation.ObservationManagerFactory - EventConsumer threw exception: java.lang.IllegalStateException: not in itialized [java] 2005-11-24 22:58:41,764 [ObservationManager] DEBUG org.apache.jackrabbit.core.observation.ObservationManagerFactory - Stacktrace: [java] java.lang.IllegalStateException: not initialized [java] at org.apache.jackrabbit.core.security.SimpleAccessManager.isGranted(SimpleAccessManager.java:119) [java] at org.apache.jackrabbit.core.observation.EventConsumer.consumeEvents(EventConsumer.java:231) [java] at org.apache.jackrabbit.core.observation.ObservationManagerFactory.run(ObservationManagerFactory.java:161) [java] at java.lang.Thread.run(Thread.java:595) [java] received events: [java] Event[path=/sample node/jcr:primaryType|type=4|userID=bogus] [java] Event[path=/sample node/sample property|type=4|userID=bogus] [java] Event[path=/sample node|type=1|userID=bogus] [java] 2005-11-24 22:58:41,764 [ObservationManager] DEBUG org.apache.jackrabbit.core.observation.ObservationManagerFactory - event delivery finished. For Tobias: my listener is extremly simple (I don't even use IllegalStateException): public class DummyEventListener implements EventListener { public DummyEventListener() { System.out.println("constructor called"); } /** * @see javax.jcr.observation.EventListener#onEvent(javax.jcr.observation.EventIterator) */ public void onEvent(EventIterator iterator) { System.out.println("received events: "); for (; iterator.hasNext();) { try { System.out.println(toStringEvent(iterator.nextEvent())); } catch (RepositoryException e) { System.err.println("exception while listnening " + SessionFactoryUtils.translateException(e)); } } } private String toStringEvent(Event event) throws RepositoryException { // do some formatting and pretty printing return string; } } For some reason SimpleAccessManager is not initialized but I have no idea why this happens - I'm not using any specific JackRabbit API just the JSR-170. Considering that the number of WARNs varies, I think it's a threading issue. > Costin Leau wrote: >> Hello, >> >> I'm trying to use EventListener but I keep getting these messages - >> sometimes 3, sometimes one and sometimes none. >> [java] 2005-11-24 17:05:30,489 [ObservationManager] WARN >> org.apache.jackrabbit.core.observation.ObservationManagerFactory - >> EventConsumer threw exception: java.lang.IllegalStateException: not in >> itialized >> [java] 2005-11-24 17:05:30,489 [ObservationManager] WARN >> org.apache.jackrabbit.core.observation.ObservationManagerFactory - >> EventConsumer threw exception: java.lang.IllegalStateException: not in >> itialized >> [java] 2005-11-24 17:05:30,489 [ObservationManager] WARN >> org.apache.jackrabbit.core.observation.ObservationManagerFactory - >> EventConsumer threw exception: java.lang.IllegalStateException: not in >> itialized >> >> I have no idea what causes this messages.
