试图在 ubuntu 上通过公共 IP 设置 RMI 但徒劳无功。我已经设置了http隧道。RMI 服务器/applet 客户端在局域网上成功运行，ubuntu 作为 RMI 服务器。通过互联网，我能够在 1099 上成功运行服务器，将对象导出到固定端口 1100。我已将 1099 和 1100 端口转发到 ubuntu 192.168.1.XXX 的本地 IP。我还在 rmi 服务器和客户端上设置了以下内容

[rmiHostName = public ip]

//configuration
System.setProperty("java.security.policy","http://"+rmiHostName+"/basedir/rmi/java.policy");
System.setProperty("java.rmi.server.hostname",  rmiHostName);//external ip address
System.setProperty("java.rmi.server.codebase",http://"+rmiHostName+"/basedir/rmi/xxx-xxx-1.0.jar");

但是我收到以下异常：

network: Connecting public-ip/cgi-bin/java-rmi.cgi?forward=1099 with proxy=DIRECT

你们能帮我解决这个问题吗？

java.rmi.NotBoundException: //public-ip:1099/MyServer

您尚未将远程对象绑定到位于 //public-ip:1099 的注册表中，名称为 MyRegistry。
