我有folloving RMI服務器:RMI無法找到綁定的對象?
public static void main(String[] args) {
try{
ChatSystemImpl chatSystem = new ChatSystemImpl();
ChatSystem chatSystem_stub = (ChatSystem) UnicastRemoteObject.exportObject(chatSystem, 6001);
Registry registry = LocateRegistry.getRegistry("localhost", 6001);
registry.bind("ChatSystem1", chatSystem_stub);
System.out.println("Server up.");
}
catch(Exception ex){
ex.printStackTrace();
}
}
當我運行它,我得到:
ava.rmi.NoSuchObjectException: no such object in table
at sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(StreamRemoteCall.java:273)
at sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java:251)
at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:377)
at sun.rmi.registry.RegistryImpl_Stub.bind(Unknown Source)
at fr.inp.ensimag.examples.chatsystem.Main.main(Main.java:30)
嗯,我不知道什麼是錯......它凝視更多2小時,然後馬上。
這是接口(如果需要):
public interface ChatSystem extends Remote{
void registerUser(UserInfo newUser) throws RemoteException;
void unregisterUser(UserInfo user) throws RemoteException;
boolean userExists(UserInfo user) throws RemoteException;
void send(MessageInfo message) throws RemoteException;
}
的實施,如下頭,身體只包含未真正落實,他們只是thow UnsupportedOperationException
方法:
public class ChatSystemImpl implements ChatSystem
的ChatSystem
接口在其他項目中,然後是源代碼的其餘部分,如果它是任何重要的。
謝謝。
