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

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.
