※ 引述《NightPrince (shooting star)》之銘言： : 我寫了一個簡單的RMI程式， : 部分程式碼如下： : LocateRegistry.createRegistry(1099);//啟動registry server : String serverObject = "rmi://localhost/serverObject"; : Naming.rebind(serverObject,temp); : 在rmi://那，我如果寫localhost就沒問題 : 寫 domain name 就會有問題，我LAB的DN是 blue.iim.ncku.edu.tw : 也就是 rmi://blue.iim.ncku.edu.tw/serverObject : LAB只有一個public IP Addr. ，所以LAB所有的電腦都是使用 : Class C private IP Addr. 然後透過那個 public IP Addr. 連上網路 : 以往，我要用我電腦架站，只要去 IP 分享器設定我這個 private IP Addr. : 要用那個PORT架設，就把那個port對應到我這個 private IP Addr. 即可 : 1099 port 我已經設定對應到我這個 private IP Addr. ，結果打上DN : 就無法運作，不知我哪裡出了問題？順便附上錯誤訊息 XD Exception in thread "main" java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.AccessException: Registry.Registry.rebind disallowed; origin /140.116.96.181 is non-local host at sun.rmi.server.UnicastServerRef.oldDispatch(Unknown Source) at sun.rmi.server.UnicastServerRef.dispatch(Unknown Source) at sun.rmi.transport.Transport$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Unknown Source) at sun.rmi.transport.tcp.TCPTransport.handleMessages(Unknown Source) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(Unknown Source) at java.lang.Thread.run(Unknown Source) at sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(Unknown Source) at sun.rmi.transport.StreamRemoteCall.executeCall(Unknown Source) at sun.rmi.server.UnicastRef.invoke(Unknown Source) at sun.rmi.registry.RegistryImpl_Stub.rebind(Unknown Source) at java.rmi.Naming.rebind(Unknown Source) at songServerImpl.main(songServerImpl.java:67) Caused by: java.rmi.AccessException: Registry.Registry.rebind disallowed; origin /140.116.96.181 is non-local host at sun.rmi.registry.RegistryImpl.checkAccess(Unknown Source) at sun.rmi.registry.RegistryImpl.rebind(Unknown Source) at sun.rmi.registry.RegistryImpl_Skel.dispatch(Unknown Source) at sun.rmi.server.UnicastServerRef.oldDispatch(Unknown Source) at sun.rmi.server.UnicastServerRef.dispatch(Unknown Source) at sun.rmi.transport.Transport$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Unknown Source) at sun.rmi.transport.tcp.TCPTransport.handleMessages(Unknown Source) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(Unknown Source) at java.lang.Thread.run(Unknown Source) -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.116.96.181
