Felix Meschberger commented on FELIX-2961:
------------------------------------------
What exactly do you have in mind for option 2 ? As it stands, it is a
compile-time constant (actually ending in the constant pool section of the
class).
But then you should anyway be able to do this:
@Component(name=TheClass.SOME_NAME_FIELD)
class TheClass {
private static final String SOME_NAME_FIELD="some constant";
}
Right ?
> SCR & ConfigurationAdmin : service.pid resolution
> -------------------------------------------------

> Key: FELIX-2961
> URL: https://issues.apache.org/jira/browse/FELIX-2961
> Project: Felix
> Issue Type: Bug
> Components: Declarative Services (SCR)
> Affects Versions: scr-1.6.0
> Reporter: Andrei Pozolotin
>
> hello!
> when I use config admin to control instaniation of scr component services, I
> use this pattern:
> // 1) in config source bundle:
> Configuration config =
> configAdmin.getConfiguration("ZZZ", null);
> Dictionary<String, String> props =
> config.getProperties();
> config.update(props);
> // 2) in config target bundle:
> @Service
> @Component(name = "AAA", policy = ConfigurationPolicy.REQUIRE, immediate =
> true)
> public class BucketPlugin implements PluginSpaceService {
> @Property(name = "service.pid")
> protected static final String PID = "ZZZ";
> // 3) despite the fact service.pid "looks good" in xml for the tagret
> compenent:
> <scr:component enabled="true" immediate="true" name="AAA"
> configuration-policy="require">
> <implementation class="com.ddfplus.core.space.BucketPlugin"/>
> <service servicefactory="false">
> <provide interface="com.ddfplus.api.plugin.PluginSpaceService"/>
> </service>
> <property name="service.pid" type="String" value="ZZZ"/>
> // 4) the scr fails to initialize the component; intitialzation works only
> when
> (scr.component.name == config.service.pid) and NOT when (config.service.pid
> == scr.component.property.pid)
> // 5) if I look on the the config target in console (when I do manage to
> inititialize it),
> it shows that again, actual service.pid comes from scr.component.name and not
> from scr.component.property.service.pid
> thank you.
