感谢。
更新＃2
感谢Brian发布该文档版本。我从那里拿了IDL，经过微调，我可以用attach_push给objNotiServer打电话。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()然后当通知进来时，我将在我的IRPManager对象中收到它们，是吗？
答案 0 :(得分：4)
CORBA :: MARSHAL例外通常是由于以下原因之一而发生的：
原因＃2现在真的不太可能，因为ORB已经足够成熟，很少发生这种情况。只要您在本世纪构建的客户端和服务器端使用ORB产品，那么您可能还可以。这留下了理由＃1。
您正在调用的方法的IDL（我相信）来自this document，看起来像这样：
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);
请注意第一个参数，它的类型为Object。但是在您的代码中，您传递的是字符串。但是，IDL类型Object在Java中映射到org.omg.CORBA.Object，而不是String。我原本希望看到你通过objNotiServer代替这个参数。
因此，您的IDL与您的服务器所期望的（可能）不匹配，或者您的IDL编译器未遵循基本的IDL-to-Java映射规则（不太可能）。
无论哪种方式，那里闻起来都很糟糕。我不相信ORB将隐式为您调用ORB.string_to_object()，因此当服务器实际期望字符串化的Object引用时，这将导致在网络上发送常规字符串。区别很小但可能是服务器向您抛出MARSHAL的原因。
因此，您的第一个停靠点应该是检查您用于构建客户端的IDL文件。确保您为要尝试呼叫的服务器获得了准确且正确的IDL。如果存在任何不匹配，那么MARSHAL例外将会发生，并且会发生很多事情。
答案 1 :(得分：2)
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/客户端上有所不同导致此错误。
您必须查看服务器的日志文件。如果您无权访问服务器，请实现自己的虚拟服务器并查明它是否有效。
关于manager_reference，请在您自己的代码中通过：narrow和对_non_existent()的调用对其进行测试。即。
org.omg.CORBA.Object managerObj = orb.string_to_object(manager_reference);
IRPManager managerImpl = IRPManagerHelper.narrow(managerObj);
managerImpl._non_existent()
如果这样可行，则您的IRPManager服务方可以正常工作。
顺便说一下，你有很多未使用的导入，应该重构它们。您的IDE会帮助您。
Update2
Yout Alarmclient必须实现StructuredPushConsumer（请参阅Initializing Corba notification service in java successfully but cannot get any events in linux but it's done in windows）并订阅通知。
但我建议打开一个新问题。
答案 2 :(得分：1)
您的代码看起来很可疑，您从未在POA中激活irpMan，但您确实使用了servant_to_reference。尝试下面的代码，将其作为伪代码处理，我没有测试它，我通常编写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);
