私は、クライアントがサーバー上で実行されているオブジェクトからメソッドを呼び出せるようにする典型的なクライアント&を持っています。私はこの状況を解決するためにJava RMIを使用します。Java RMIの実装
サーバー側のコードは以下であり、それはコンパイルし、正常に動作：テスト目的のために
ServerInt.java
package gpio.control;
import java.rmi.Remote;
import java.rmi.RemoteException;
public interface ServerInt extends Remote{
public void setHeizung(boolean x) throws RemoteException;
public void quitError() throws RemoteException;
public void startPWM(int periode,int pulsbreite,int pulsanzahl) throws RemoteException;
}
ServerImpl.java
package gpio.control;
import java.rmi.RemoteException;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
import java.rmi.server.RemoteServer;
import java.rmi.server.UnicastRemoteObject;
public class ServerImpl implements ServerInt{
private Model myModel;
public ServerImpl(Model m) throws RemoteException {
myModel = m;
LocateRegistry.createRegistry(1099);
ServerInt stub = (ServerInt) UnicastRemoteObject.exportObject(this, 1099);
RemoteServer.setLog(System.out);
Registry registry = LocateRegistry.getRegistry();
registry.rebind("Server1", stub);
}
@Override
public void setHeizung(boolean x) throws RemoteException {
myModel.setHeizung(x);
}
@Override
public void quitError() throws RemoteException {
myModel.quitError();
}
@Override
public void startPWM(int periode, int pulsbreite, int pulsanzahl) throws RemoteException {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
}
、私はまた、小さなクライアントを作成しましたサーバーアプリケーションと同じサーバー上で実行されるアプリケーション：
Client.java
package client;
import java.rmi.NotBoundException;
import java.rmi.RemoteException;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
public class Client {
public static void main(String[] args) throws RemoteException, NotBoundException {
Registry registry = LocateRegistry.getRegistry();
ServerInt serverint = (ServerInt) registry.lookup("rmi://127.0.0.1:1099/Server1");
serverint.setHeizung(true);
}
}
私は今、クライアントプログラムを実行すると、私は次のエラーを取得します。クライアントから エラー：

何午前私はここで間違っている？ Client.java変化を
@Mr_Thorynqueいいえ、彼はそうではありません。 – EJP
