我正在尝试订阅类似于 ( org.omg.CORBA.MARSHAL: Server-side Exception: null )! 的通知服务和消费者警报，但出现编组错误。非常感谢有人可以帮助我解决我所缺少的或做错的事情。

idls 文件来自NotificationIRP idls并使用 jacorb-3.5 api。

NotificationConsumer.java

import org.omg.CORBA.*;
import org.omg.CORBA.ORB;

import java.io.*;

public class NotificationConsumer {

    private static String notifIRPName = "com/ericsson/nms/cif/service/NMSNAConsumer";
    private static String notifIRPPortal = "com/ericsson/nms/cif/service/NMSNAPortal";

    public static void main(String args[]) throws IOException {
  try{
  //initialize ORB
   org.omg.CORBA.ORB orb = ORB.init(args, null);

  //read stringified object from file
  FileReader fr = new FileReader("ExternalNamingService.1");
  BufferedReader br = new BufferedReader(fr);
  String ior = br.readLine();
  org.omg.CORBA.Object obj = orb.string_to_object(ior);

  NamingContextExt ncRef = NamingContextExtHelper.narrow(obj);
  org.omg.CORBA.Object notiObj = ncRef.resolve_str(notifIRPName);

  //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);
}

} }

结果

我想这里的问题是你需要在 orb.init() 之后在新的 CORBA 中使用命名服务之前添加注册商。当您使用 orb 传递任何对象时，它会尝试检查该对象是否已向任何服务注册。否则它开始封送数据。我正在查看您的代码，将尽快找到解决方案

你想通了吗？我正在尝试同样的事情，连接到 Ericsson Corba 北向接口，但在 Perl 中，而不是在 Java 中。

您正在向 attach_push() 发送错误的对象，对象类型必须是：

  • manager_reference：纯字符串，
  • time_tick: ManagedGenericIRPConstDefs::UnsignedLongOpt，不是你代码中的int！
  • 猫：NotificationIRPConstDefs::NotificationCategorySet，而不是字符串数组。
  • 过滤器：ManagedGenericIRPConstDefs::StringOpt，而不是字符串。

此外，您正在尝试发送猫中的所有类别，但包括事件和 qos。对于您需要使用专有 EventIRP 而不是 NotificationIRPSystem 和您可能不需要的 qos 的事件。对于警报，您只能使用一个类别“1f1”。在 Perl 中是这样完成的：

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

尝试在 Java 中找出相同的东西。它对我不起作用，工作仍在进行中......
