Thank you Tim,
Ok thats really amazing! That was exactly what i was looking for. I can change the name target name with @Referance(name="foo") so a bit more transparency. Each day I am discovering something like this i like OSGI and Karaf a bit more. br, Matthias ________________________________ Von: Tim Ward <tim.w...@paremus.com> Gesendet: Mittwoch, 15.

In this case you should add the configuration property service.target to your configuration dictionary with the value being an LDAP filter selecting the service you want to inject. Note that “service” is the name of your reference (it defaults to the field name) and that if your reference has a different name (e.g. if you change the name of the field) then the name of the property will change too. For example: service.target=(foo=bar) Inject me with a MyInterfaceB which has the service property foo equal to bar.

For Example you have a component: @Component( configurationPid = "MyInterfacA.factory", configurationPolicy = ConfigurationPolicy.REQUIRE, public Class MyInterfaceAImpl implements MyInterfacA{ @Reference MyInterfaceB service; ...} During runtime I create multiple services from type MyInterfaceB and multiple componentes of MyInterfaceAImpl with configadmin. Depending on the configuration of MyInterfaceAImpl I want to filter which MyInterfaceB implementation is injected. I thought about FindHook but there I dont see a way how to get the information which service from the bundle is requesting the reference. Is there any chance to do this, or do I have to go for an alternative design. Or a better way to isolate services from another? Best regards, Matthias
