我正在尝试订阅类似于（org.omg.CORBA.MARSHAL：服务器端异常：null）！的通知服务和消费者警报，但出现编组错误。如果有人可以帮助我解决我遗漏或做错的事情，非常感谢。
idls 文件来自 NotificationIRP idls 并使用 jacorb-3.5 api。

我想这里的问题是，即使在 orb.init() 之后的新 CORBA 中使用命名服务，您也需要添加注册器。当您使用 orb 传递任何对象时，它会尝试检查该对象是否已在任何服务中注册。否则它开始整理数据。我正在查看您的代码，很快就会尝试找到解决方案
你明白了吗？ 我正在尝试同样的事情，连接到爱立信 Corba 北向接口，但使用 Perl，而不是 Java。
您向 Attach_push() 发送了错误的对象，对象类型必须准确：
此外，您正在尝试发送 cats 中的所有类别，但包括事件和 qos。对于需要使用专有的 EventIRP 而不是 NotificationIRPSystem 的事件，您可能不需要的 qos。对于警报，您只能使用一个类别“1f1”。在 Perl 中，它是这样完成的：
my $category_set=NotificationIRPConstDefs::NotificationCategorySetOpt->new();
$category_set->value(["1f1"]);
尝试在 Java 中找出同样的东西。它对我来说还不起作用，工作仍在进行中......
问题解决了吗？如果是的话，你做了什么改变？
