Hi @Madhur-Madan,

On OSGi service level you should use Reference annotation. So this will be option you should use in case you want to get reference of other OSGi service inside another.

import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Reference;

@Component
public class YourService {
   
   @Reference
   private OtherService otherService;
}

OSGiService annotation is dedicated for Sling Model it will not work inside OSGi service/component. You can use it, in case you would like to inject OSGi Service into your Sling Model.
