Hi,


@Path("/say")
@ApplicationScoped
public class HelloClientEndpoint {

    private final static String USER = "user";
    private final static String PWD = "password";

    @Inject
    @Protocol("http") @ServiceName("swarm-rest")
    private String helloService;

to resolve the issue as I get a null object for helloService when Swarm is deployed on OpenShift ?

- The service is well published

oc get services
NAME              CLUSTER-IP       EXTERNAL-IP                     PORT(S)                   AGE
docker-registry   172.30.165.13    <nodes>                         5000/TCP                  2h
kubernetes        172.30.0.1       <none>                          443/TCP,53/UDP,53/TCP     2h
swarm-rest        172.30.175.186   172.46.234.198,172.46.234.198   80/TCP                    2h

Many thanks in advance for your help

Simply use "swarm-rest" as your service name as it gets resolved via DNS:

private String helloService = "swarm-rest";

Try replace those 3 lines with:

   private String helloService = "http://swarm-rest";

which is much simpler code & works with any DI framework and without one too
