谢谢

更新#2

感谢Brian发布了该版本的文档。我从那里获取了IDL，只需稍作调整，就可以用我的

objNotiServer

调用

attach\u push

。我的下一个问题是如何设置我的

AlarmClient

以接收这些通知。我的假设是，我可以调用

orb.run（）

，然后当通知传入时，我将在我的IRPManager对象中接收它们，对吗

您的代码看起来可疑，您从未在POA中激活irpMan，但您确实使用SERVIDER\u to\u引用。试试下面的代码，把它当作伪代码处理，我还没有测试它，我通常程序C++。

   IRPManager irpMan = new IRPManager();
   POA poa = POAHelper.narrow(orb.resolve_initial_references("RootPOA"));
   poa.the_POAManager().activate();
   ObjectId id = poa.activate_object (irpMan);
   org.omg.CORBA.Object objNotiServer = poa.id_to_reference(id);
   String manager_reference = orb.object_to_string(objNotiServer);
   System.out.println("MANAGER REF: " + manager_reference);
   System.out.println("OBJ NOTI SERVER: " + objNotiServer);
   int time_tick = 15;
   String filter = "";
   String[] asd = {};
   NotificationIRPConstDefs.EventTypesSetHolder e_list = new NotificationIRPConstDefs.EventTypesSetHolder();
      NotificationIRPConstDefs.ExtendedEventTypesSetHolder ex_list = new NotificationIRPConstDefs.ExtendedEventTypesSet\
Holder();
   String cats[] = tt.get_notification_categories(e_list, ex_list);
   String res = tt.attach_push(objNotiServer, time_tick, asd , filter);

您的代码看起来可疑，您从未在POA中激活irpMan，但您确实使用servant_to_引用。试试下面的代码，把它当作伪代码处理，我还没有测试它，我通常程序C++。

   IRPManager irpMan = new IRPManager();
   POA poa = POAHelper.narrow(orb.resolve_initial_references("RootPOA"));
   poa.the_POAManager().activate();
   ObjectId id = poa.activate_object (irpMan);
   org.omg.CORBA.Object objNotiServer = poa.id_to_reference(id);
   String manager_reference = orb.object_to_string(objNotiServer);
   System.out.println("MANAGER REF: " + manager_reference);
   System.out.println("OBJ NOTI SERVER: " + objNotiServer);
   int time_tick = 15;
   String filter = "";
   String[] asd = {};
   NotificationIRPConstDefs.EventTypesSetHolder e_list = new NotificationIRPConstDefs.EventTypesSetHolder();
      NotificationIRPConstDefs.ExtendedEventTypesSetHolder ex_list = new NotificationIRPConstDefs.ExtendedEventTypesSet\
Holder();
   String cats[] = tt.get_notification_categories(e_list, ex_list);
   String res = tt.attach_push(objNotiServer, time_tick, asd , filter);

服务器端有问题，因此您收到服务器端异常

您的IDL在服务器/客户端上不同，这会导致此错误

您必须查看服务器的日志文件。如果您没有访问服务器的权限，请实现您自己的虚拟服务器，并了解它是否工作

关于

manager\u参考

，请通过以下方式在您自己的代码中进行测试：

shorrow

，并调用

\u non\u existence（）

。即

org.omg.CORBA.Object managerObj = orb.string_to_object(manager_reference);
IRPManager managerImpl = IRPManagerHelper.narrow(managerObj);
managerImpl._non_existent()

如果这样做有效，您的IRPManager仆人也会起作用

顺便说一下，您有很多未使用的导入，应该重构它们。您的IDE将帮助您

对于更新2

Yout Alarmclient必须实现StructuredPushConsumer（请参阅）并订阅通知

但是我建议打开一个新问题

CORBA:：封送异常通常是由于以下原因之一发生的：

客户端和服务器之间的IDL不匹配（导致意外的负载差异）

糟糕的ORB产品，不知道如何正确解组复杂但有效的有效负载

原因2如今真的不太可能了，因为球体已经足够成熟，这种情况很少发生。只要您在本世纪构建的客户端和服务器端都使用ORB产品，那么您可能就可以了。这就剩下理由了

您正在调用的方法的IDL（我相信）来自，如下所示：

interface NotificationIRPOperations {
  NotificationIRPConstDefs::SubscriptionId attach_push (
    in Object manager_reference,
    in long time_tick,
    in NotificationCategorySet notification_category_set,
    in string filter
  )
  raises (Attach, ParameterNotSupported, InvalidParameter, AlreadySubscribed,
          AtLeastOneNotificationCategoryNotSupported);

注意第一个参数，它的类型是

Object

。但是，在代码中，传递的是字符串。但是，IDL类型

Object

在Java中映射到

org.omg.CORBA.Object

，而不是映射到

字符串。我本希望看到您通过objNotiServer
而不是此参数
因此，要么您的IDL与服务器期望的不匹配（可能），要么您的IDL编译器没有遵循基本的IDL到Java映射规则（可能）
不管怎样，那里有些东西闻起来很难闻。我不相信ORB会为您隐式地调用ORB.string\u to\u object（）
，因此，当服务器实际需要字符串化对象引用时，这将导致在网络上发送常规字符串。区别很微妙，但这可能是服务器向您抛出封送处理的原因
因此，您的第一个调用端口应该是检查用于构建客户机的IDL文件。确保您为您试图调用的服务器获得了准确的IDL。如果存在任何不匹配，则会发生异常，并且会发生很多异常。
