RE: [ecf-dev] Distributed EventAdmin Service

["Konradi, Philipp" <philipp.konradi@xxxxxxxxxxx>]

Hi,

The EVENT_FILTER supplied with an EventHandler is only evaluated on
event properties.
Roshan, this means in your example that the event you sent should have a
property "topic" with value "defaultTopic" to be delivered to the event
handler you described. I'd first verify this.
 
In addition to Scott's example:
EventConstants.EVENT_TOPIC can also be supplied directly to
event-handlers service registration properties. Like this:

Dictionary d = new Hashtable();
d.put(EventConstants.EVENT_TOPIC, topics );
d.put(EventConstants.EVENT_FILTER,
"(my_event_property=foo.*)" );
context.registerService( EventHandler.class.getName(), this, d );

Thanks, Philipp
BTW: I filed right now a bug / feature request on adding
EventConstants.EVENT_TOPIC evaluation to in DistributedEventAdmin
implementation (to make it spec compliant). 
That might be the cause for the problem you describing as well.
