CORBA Notification Subscription (ERROR: org.omg.CORBA.MARSHAL: vmcid: 0x0 minor code: 0 completed: No)

Question

I'm trying to subscribe to Notification Service and consumer alarms similar to (org.omg.CORBA.MARSHAL: Server-side Exception: null)!, but getting marshalling errors. Many thanks if someone can help me with what I'm missing or doing wrong.

The idls files are from NotificationIRP idls and using jacorb-3.5 api.

  //read stringified object from file

  //get notification operations object
  NotificationIRPOperations nOps = NotificationIRPOperationsHelper.narrow(notiObj);
  System.out.println("NOTIFICATION|" + nOps);

  //activate poa manager
  IRPManager iManager = new IRPManager();
  POA poa = POAHelper.narrow(orb.resolve_initial_references("RootPOA"));
  poa.the_POAManager().activate();
  org.omg.CORBA.Object notiServerObj = poa.servant_to_reference(iManager);

  //subscribe to notifications
  String manager_reference = orb.object_to_string(notiServerObj);
  System.out.println("MANAGER REF|" + manager_reference);
  int time_tick = 15;
  String filter = "";
  String[] asd = {};
  NotificationIRPConstDefs.EventTypesSetHolder e_list = new NotificationIRPConstDefs.EventTypesSetHolder();
  NotificationIRPConstDefs.ExtendedEventTypesSetHolder ex_list = new NotificationIRPConstDefs.ExtendedEventTypesSetHolder();
  String cats[] = nOps.get_notification_categories(e_list, ex_list);

  String vers[] = nOps.get_notification_IRP_version();
  for (String ver : vers){
    System.out.println("notification IRP version is: " + ver);
  }

  String resp = nOps.attach_push(manager_reference, time_tick, cats, filter);

  //print subscription ids
  String subs[] = nOps.get_subscription_ids(manager_reference);
  for (String sub : subs){
    System.out.println("subscription id: "+sub);
  }

  } catch (Exception ex){
     System.out.println ("ERROR: " + ex);
}

} }

Result

Problem i guess here is you will need to add registrar before even you use naming service in new CORBA right after orb.init(). When you pass any object with orb it tries to check if that is already registered with any service. else it starts marshaling data. I am looking inside your code will try to find solution soon

that would be really great if you could figure out whats wrong with my callback object. many thanks – user2326017 Feb 13 '15 at 01:36

Did you figure this out? I'm trying the same thing, to connect to Ericsson Corba northbound interface, but in Perl, not in Java.

You are sending wrong objects to attach_push(), object types need to be exactly:

manager_reference: plain string,
time_tick: ManagedGenericIRPConstDefs::UnsignedLongOpt, not int as in your code!
cats: NotificationIRPConstDefs::NotificationCategorySet, not string array.
filter: ManagedGenericIRPConstDefs::StringOpt, not string.

Also, you are trying to send all categories in cats but that includes events and qos. For events you need to use proprietary EventIRP instead of NotificationIRPSystem and qos you probably don't need. For alarms you can use just one category "1f1". In Perl it's done like this:

my $category_set=NotificationIRPConstDefs::NotificationCategorySetOpt->new();
$category_set->value(["1f1"]);

Try to figure out the same thing in Java. It's not working for me yet, work is still in progress...
