- Does bundle:headers for the REST bundle have a required capability to the
Person Service, foo.bar.PersonService in the example below.
karaf@root> bundle:headers <REST_bundle_id>
...
Require-Capability =
osgi.service;effective:=active;filter:=(objectClass=foo.bar.PersonService),
...
karaf@root>
My assumption is the requirement is missing, meaning the requirement in the
REST bundle is not defined correctly.
