Doubt about Javaee with Wildfly 18

Question

I would like to know what this log is about.

[org.jboss.as.ejb3.deployment] (MSC service thread 1-5) WFLYEJB0473: JNDI bindings for session bean named 'ContaService' in deployment unit 'deployment "Backend.war"' are as follows:

    java:global/Backend/ContaService!com.hybridnetwork.service.ContaService
    java:app/Backend/ContaService!com.hybridnetwork.service.ContaService
    java:module/ContaService!com.hybridnetwork.service.ContaService
    ejb:/Backend/ContaService!com.hybridnetwork.service.ContaService
    java:global/Backend/ContaService
    java:app/Backend/ContaService
    java:module/ContaService

I noted it as a simple stateless:

@Stateless
public class ContaService {

    public List<ContaDTO> list() {
        return Collections.emptyList();
    }

}

I injected it this way:

@Path("contas")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class ContaRest {

    @Inject
    ContaService contaService;

    @GET
    public Response listarTodos() {
        return Response.ok(contaService.list()).build();
    }

}
