ERROR org.omg.CORBA.MARSHAL Sequenzlänge zu groß

Question

Nach dem erfolgreichen Alarme von Corba U2000-Server holen und jetzt die Werte zu lesen, erhalte ich den Fehler unter

ERROR: org.omg.CORBA.MARSHAL: Sequence length too large. Only 12 available and trying to assign 31926513 vmcid: 0x0 minor code: 0 completed: No

Oder ist meine Art, die Alarmliste zu lesen, falsch? Vielen Dank.

Sie können die Beispielverfahren unten getAlarmList

//Connect to AlarmIRP 
AlarmIRP alarmIRP = AlarmIRPHelper.narrow(orb.string_to_object(alarmIrpIOR.value)); 
StringTypeOpt alarmFilter = new StringTypeOpt(); 
alarmFilter.value(""); 
DNTypeOpt base_object = new DNTypeOpt(); 
base_object.value(""); 
BooleanHolder flag = new BooleanHolder(false); // false for iteration 
AlarmInformationIteratorHolder iter = new AlarmInformationIteratorHolder(); 

List<String> alarmIds = get_alarm_list(alarmIRP, alarmFilter, base_object, flag, iter); 

private List<String> get_alarm_list(org._3gppsa5_2.AlarmIRPSystem.AlarmIRP alarmIRP, org._3gppsa5_2.ManagedGenericIRPConstDefs.StringTypeOpt alarmFilter, org._3gppsa5_2.AlarmIRPConstDefs.DNTypeOpt base_object, BooleanHolder flag, org._3gppsa5_2.AlarmIRPSystem.AlarmInformationIteratorHolder iter) throws org._3gppsa5_2.AlarmIRPSystem.GetAlarmList, org._3gppsa5_2.ManagedGenericIRPSystem.ParameterNotSupported, org._3gppsa5_2.AlarmIRPSystem.NextAlarmInformations, org._3gppsa5_2.ManagedGenericIRPSystem.InvalidParameter, BAD_OPERATION { 
    logger.info("[get-alarm-list][start]"); 
    alarmIRP.get_alarm_list(alarmFilter, base_object, flag, iter); 

    List<StructuredEvent> alarms = new ArrayList(); 
    EventBatchHolder alarmInformation = new EventBatchHolder(); 
    short alarmSize = 100; 
    List<String> alarmIds = new ArrayList(); 
    while (iter.value.next_alarmInformations(alarmSize, alarmInformation)) { 
     alarms.addAll(Arrays.asList(alarmInformation.value)); 
     logger.info("Current alarm size:" + alarms.size()); 
    } 

    for (StructuredEvent event : alarms) { 
     try { 
     //printAlarm(event); 
     } catch (Exception ex) { 
     } 
     List<Property> rem = new ArrayList<Property>(); 
     rem.addAll(Arrays.asList(PropertySeqHelper.extract(event.remainder_of_body))); 
     for (Property property : rem) { 
     if (!property.name.equals(org._3gppsa5_2.AlarmIRPNotifications.NotifyNewAlarm.ALARM_ID)) { 
      continue; 
     } 

     alarmIds.add(property.value.extract_string()); 
     } 
    } 
    logger.info("[get-alarm-list][completed] size :" + alarms.size()); 

    return alarmIds; 
}

ich es geschafft, herauszufinden, was finden, dass filterableData.value.toString() Wert ist, der „org.jacorb.orb.CDROutputStream“ ist. Es stellt sich heraus, dass die Eigenschaft mit dem Namen "b" ist ein TimeBase:: UtcT nach den Dokumenten.

es zu konvertieren Wert zu korrigieren, die ein UTC-Zeitstempel ist, dass ich die Bedingung

if (filterableData.name.equals("b") && filterableData.value != null && filterableData.value.toString().contains("org.jacorb.orb.CDROutputStream")) { 
    long occuranceTime = TimeTHelper.read(filterableData.value.create_input_stream()); 
    System.out.println("data.value: " + occuranceTime); 
}
