hummm... think I got the idea now...
I will create another component to consume the registered service and
see if the activate method is being called...
thanks again,
Cristiano

Thanks David and Neil,
Humm, I don't think I understood yet.
Ok, I don't have any other bundle/component consuming this service, yet.
but in this case why I have an instance of the service that received the
configuration from CM registered ?
You don’t have an instance… you have a service registration. When another
bundle sees this in the service registry and calls getService(), then an
instance of the class will be created in order to provide the service. This is
a key laziness feature offered by DS.

Look at the log below:
18:54:13.557 INFO : com.c4biz.feast.kernel.lib [ OSGI_BUNDLE ]:
ServiceEvent REGISTERED
[S:{com.c4biz.feast.FixedControllerService}={service.pid=fixed.controller-1467064453446-0,
service.factoryPid=fixed.controller,
component.name=com.c4biz.feast.ComponentControllerServiceProvider,
extenderAlias=ConfigurationManifestHeaderExtender,
targetBundleStateMask=32, component.id=4,
targetTrackingMode=manifest_header, service.id=56,
service.bundleid=18, service.scope=prototype}]

Probably lazy activation. Your component is a service, of type
FixedControllerService. No instances will be created until a consumer binds to
it.

Hello,
I'm facing a situation that I'm not understanding. I'm using
org.apache.felix.scr 2.0.2.
I've set a component with this annotation:
@Component(enabled = true, configurationPolicy =
ConfigurationPolicy.REQUIRE,
scope = ServiceScope.PROTOTYPE, service =
FixedControllerService.class,
configurationPid = {SERVICE_FACTORY_PID_CONTROLLER})
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.3.0";
name="com.c4biz.feast.ComponentControllerServiceProvider"
configuration-policy="require" enabled="true" activate="activate"
deactivate="deactivate" modified="modified"
configuration-pid="fixed.controller">
<implementation
class="com.c4biz.feast.ComponentControllerServiceProvider"/>
<service scope="prototype">
<provide interface="com.c4biz.feast.FixedControllerService"/>
</service>
</scr:component>
In this component class I have a method (activate()) tagged with @Activate
annotation. And there are any reference bind being used for now.
From another bundle I'm creating a configuration using factoryPID =
SERVICE_FACTORY_PID_CONTROLLER.
Interesting is that the service are being created and with in a proper
autogenerated PID and passed properties. At least I can see it when listing the
services using gogo console.
also scr:list tells me that the component is enabled and satisfied.
What I'm not understanding is that the activate method is not being called...
could someone explain me what am I missing here?
thanks,
Cristiano
