Ich kann nicht die Blaupause für die Verwendung eines Dienstes vor Ort. Der Server OSGi
(karaf
) zeigt GracePeriod und eventuell ein Timeout an, das auf ILookupMfgService
wartet.mit einer Java-Blueprint-Service-Definition
Wenn ich die Referenzlinie entferne, startet das Bündel und hat eine ILookupMfgService
zur Verfügung.
Irgendwelche Vorschläge, was ich falsch mache?
Danke für die Hilfe mit meinem Lernen!
