Hi Dishara,
The ResourceResolverFactory bundle should not be using any bundle
implementing a ResourceProvider, as that would imply a circular
dependency.
It looks like your service is starting correctly as its listed as
service ID 257, component ID 103.
Looking at the code, I dont think you have defined where the
CassandraResourceProvider is "mounted", you need to set the
provider.roots property.
ie
@Component(immediate=true, metatype=true)
@Service(ResourceProvider.class)
@Properties({
@Property(name="provider.roots", value={ "/content/cassandra"})
})
public class CassandraResourceProvider implements ResourceProvider {
This tells the ResourceResolver where in the resource tree the
CassandraResourceProvider should be registered. IIRC its required for
registration. If you look at the logs carefully you might find the
ResourceResolver reporting a problem with registration.
