Every method in a Remoteinterface must be able to throw a RemoteException. Your interface should be:
Remote接口中的每个方法都必须能够抛出RemoteException. 你的界面应该是：
public interface RemotePeer extends Remote {
public abstract void displayInf(String inf) throws RemoteException;
public abstract void exit() throws RemoteException;
public abstract boolean isActive() throws RemoteException;
}
You might want to take a look at the RMI Tutorial.
您可能想看看RMI 教程。
