Hi Miguel,
thanks for the quick answer. In my org.osgi.service.event.Event implementation there isn't a constructor (String, Map) for the event object, there is a constructor that uses a Dictionary object instead .Nevertheless the rest is equivalent to my code.
The events are posted, but it seems that it fails the conversion of the object
included in the properties object. When I construct the properties I have:
props.put("measure", (Measure)measure);
But, when I retrieve this property from the event:
Measure measure = (Measure) event.getProperty("measure");
The error is launched
ERROR - Exception while dispatching event org.osgi.service.event.Event [topic=topicName] to handler mypackage.simpleeventhand...@3e953e95
.... any ideas?
thanks!

try to use event admin this way:
String topic = "here_my_topic_to_be_filtered";
Map properties = new Properties();
[...]
Event ev = new Event(topic, properties);
and post the event this way:
_eventAdmin.postEvent ( ev );
where _eventAdmin is the service reference ...
