If I remove the
@Reference
public void setLogservice(LogService logservice) {
this.logservice = logservice;
}
then my feature loads:
karaf@root()> feature:repo-add
mvn:no.priv.bang.neo4j.karaf/neo4j-karaf/LATEST/xml/features
Adding feature url mvn:no.priv.bang.neo4j.karaf/neo4j-karaf/LATEST/xml/features
karaf@root()> feature:install neo4j-server
karaf@root()>
So I guess this means that the above message is because the service
dependency isn't satisfied...?
But why isn't the ServiceMBean service dependency satisfied from this?
karaf@root()> bundle:capabilities org.apache.karaf.system.core

Maybe I would be better off trying to inject the SystemService? (if that
does what I need to do? Yep, it appears to have the same methods, more
or less... [1])
