eventconsumer exceptions
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

[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. I assumed this has something
to do with events being asynchronous. I've added a Thread.sleep but I
still get one (I do get to log the others):
[mkdir] Created dir: C:\work\study\springmodules-0.2\workspace\springmodules\samples\jcr\.classes\repo
[java] constructor called
[java] received events:
[java] Event[path=/sample node/sample property|type=4|userID=bogus]
[java] Event[path=/sample node/jcr:primaryType|type=4|userID=bogus]
[java] Event[path=/sample node|type=1|userID=bogus]
[java] received events:

What exactly I am doing wrong here. I can provide the source code
however the code is very simple - I get a session and just attach a
listener (which simply logs) to it. Nothing special.

hi costin,
i think the session you are using is already closed when the events are cosumed.
in this situation, the events should not been sent to the listeners.
this is probably a bug.
i created a jira issue: http://issues.apache.org/jira/browse/JCR-279
thank you for reporting that
regards, toby

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] 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.

Hi Costin,
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.
regards

hi costin,
it seems, that the exception is thrown in your event listener. maybe
you add more error handling to it.
