How to use

JAXRSubsystemRootResource

in

org.jboss.as.jaxr.extension

@Override
protected Set<ManagementResourceRegistration> initializeLegacyModel(ExtensionContext context) {
  SubsystemRegistration subsystemRegistration = context.registerSubsystem(SUBSYSTEM_NAME, CURRENT_MODEL_VERSION);
  subsystemRegistration.registerXMLElementWriter(JAXRSubsystemWriter.INSTANCE);
  ManagementResourceRegistration subsystemRoot = subsystemRegistration.registerSubsystemModel(new JAXRSubsystemRootResource());
  return Collections.singleton(subsystemRoot);
}

  @Override
  public void initialize(ExtensionContext context) {
    SubsystemRegistration subsystem = context.registerSubsystem(SUBSYSTEM_NAME, MANAGEMENT_API_MAJOR_VERSION,
        MANAGEMENT_API_MINOR_VERSION, MANAGEMENT_API_MICRO_VERSION);
    ManagementResourceRegistration registration = subsystem.registerSubsystemModel(new JAXRSubsystemRootResource(config));
    registration.registerOperationHandler(GenericSubsystemDescribeHandler.DEFINITION, GenericSubsystemDescribeHandler.INSTANCE);

    // JAXR Properties
    registration.registerSubModel(new JAXRPropertyDefinition(config));

    subsystem.registerXMLElementWriter(JAXRSubsystemWriter.INSTANCE);

    JAXRSubsystemRootResource.registerTransformerers(subsystem);
  }
