推荐答案

如果您在绑定，重新绑定或查找时获得该选项，则注册表未运行。如果您进行远程调用，请参阅 RMI FAQ ，如果您运行Linux，还要检查/ etc / hosts文件是否将127.0.0.1映射到localhost，将您的真实IP地址映射到您的真实主机名 - 这是一个某些Linux发行版中常见的问题。

If you're getting that on bind, rebind, or lookup, the Registry isn't running. If you get it doing the remote call, see item A.1 in the RMI FAQ supplied with the Javadoc, and if you're running Linux also check that your /etc/hosts file maps 127.0.0.1 to localhost and your real ip address to your real hostname - this has been a common problem in some Linux distributions.
