Hi all,
i'm getting a ClassCastException when using the ServiceReference to obtain the actual service. This happens if i declare a ServiceReference in the signature of the bind-method. Everything works fine when using the service type in the method signature. I even tried to set the member-type attribute of the reference-list to "service-reference" with no sucess.
is this a bug or am i missing something?
I need the ServiceReference because i want to update the service properties by re-registering the service. Maybe there is another way to achieve this using bluprint.
<reference-list id="barrierAdapterList" interface="com.capricube.tmcs.device.api.adapters.BarrierAdapter" availability="optional" member-type="service-reference">
<reference-listener bind-method="registerBarrierAdapter" unbind-method="unregisterBarrierAdapter" ref="barrierFacade" />
</reference-list>
public void registerBarrierAdapter(ServiceReference barrierAdapterReference) {
final Object idProperty = barrierAdapterReference.getProperty(DeviceMappingConstants.DEVICE_ID);
final UUID id = UUID.fromString((String) idProperty);
final BundleContext context = barrierAdapterReference.getBundle().getBundleContext();
// throws exception
final BarrierAdapter barrierFacadeService = (BarrierAdapter) context.getService(barrierAdapterReference);
barrierAdapterMap.putIfAbsent(id, barrierFacadeService);
}
