> According to the OSGi compendium specifications 4.3.0, section 104.8.1 (page 88), the
ConfigurationAdmin should send events through the EventAdmin when it is available.
> Copy of the text:
> Configuration events must be delivered asynchronously by the Configuration Admin implementation,
if present. The topic of a configuration event must be:
> org/osgi/service/cm/ConfigurationEvent/<event type>
> The <event type> can be any of the following:
> - CM_DELETED
> - CM_UPDATED
> - CM_LOCATION_CHANGED
> The properties of a configuration event are:
> • cm.factoryPid – (String) The factory PID of the associated Configuration object,
if the target is a
> Managed Service Factory. Otherwise not set.
> • cm.pid – (String) The PID of the associated Configuration object.
> • service – (ServiceReference) The Service Reference of the Configuration Admin service.
> • service.id – (Long) The Configuration Admin service's ID.
> • service.objectClass – (String[]) The Configuration Admin service's object class
(which must
> include org.osgi.service.cm.ConfigurationAdmin)
> • service.pid – (String) The Configuration Admin service's persistent identity, if
set.
> I'd like to use the EventAdmin for this information, because it is guaranteed to have
no side effects and to be informative only.
> Now of course I could use the ConfigurationListener for this, but it seems that this
has some unwanted side effects. Unbounded configurations now seem to bind to my listenening
bundle, while I only want to present some configuration status on a Web UI. There is another
bundle to which the configuration should bind, but I use DS to do so. Maybe this is another
issue...
