我一直在尝试让我的C ++ TAO（v1.6）客户端连接到运行在 JDK1.3上的java tnameserv 。但是C ++ TAO客户端无法解析命名服务。它抛出以下异常：

请帮助我。感谢。

看起来tnameserv组件正在抛出非标准SystemException。 CORBA spec：
供应商可能会定义非标准系统异常，但这些异常 不鼓励例外，因为它们是不可携带的。一个 非标准系统异常，当传递给没有的ORB时 认识到它，应由该ORB作为UNKNOWN标准提交 系统异常。来自的次要代码和完成状态 未识别的例外应保留在UNKNOWN例外中。
但很难说出特定于供应商的次要代码（53550000）代表什么。 Oracle / Sun似乎没有关于他们的代码的文档，所以我建议打开你的tnameserv上的日志记录，看看它回馈给你的是什么。
我还建议你编写一个快速的Java 1.3 CORBA客户端，它与你的C ++ TAO客户端做同样的事情，看看是否有效。如果是这样，您的TAO C ++客户端就会遇到互操作性问题。如果它不起作用，你至少会看到神秘的SystemException的细节，它可能会引导你找到解决方案。
