RMI で作成しているマルチプレイヤー ゲームで問題が発生しています。

RMI を使用する必要があります。これはプロジェクトの要件の 1 つです。

コンパイル時に発生するエラーは次のとおりです。すでに rmiregistry がバックグラウンドで実行されています。

実行しようとしているサーバーは次のとおりです。

private void startServer(){
        //new Server();
        System.out.println(Server.class.getProtectionDomain().getCodeSource().getLocation() );

        try {
            Server obj = new Server();
            PlayerTwoControl stub = (PlayerTwoControl) UnicastRemoteObject.exportObject(obj, 0);

            // Bind the remote object's stub in the registry
            Registry registry = LocateRegistry.getRegistry(1500);
            registry.bind("Hello", stub);

            System.err.println("Server ready");
            System.out.println("WHAAAT");
        } catch (Exception e) {
            System.err.println("Server exception: " + e.toString());
            e.printStackTrace();
        }
    }

これが PlayerTwoControl クラスです。現在はほとんど空です。これを実行してコンパイルするために今必要なのは、p2 の基本的なコントロールをテストできるようにするためです。

    import java.rmi.Remote;
import java.rmi.RemoteException;

import javafx.event.EventHandler;

public interface PlayerTwoControl extends Remote{   
    EventHandler movement() throws RemoteException;
}

とりあえず動きは何も起きていません。関連する場合は、ゲームに JavaFX を使用しています。

助けてください ！

例外で指定されたクラスは、レジストリの CLASSPATH で使用できません。最も簡単な解決策は、コマンド ライン レジストリを使用する代わりに、サーバー JVM で LocateRegistry.createRegistry() を使用してレジストリを開始することです。

注意:コンパイル時にこのエラーは発生しませんでした。
