如何將JavaCard程序包添加到JavaCard小程序？

Question

我正在嘗試構建一個簡單的Hello world JavaCard小程序。我正在使用NetBeans IDE。

我正在關注本教程。

這是我的代碼：

package classicapplet1;

import javacard.framework.*;
import java.rmi.Remote;
import javacard.framework.service.Dispatcher;
import javacard.framework.service.RMIService;
import javacard.framework.service.Service;

public class JavaCardApplet extends Applet  {

    HelloWorld hello;
    Dispatcher disp;
    Service svc;

    public static void install(byte[] bArray, short bOffset, byte bLength) {
        new JavaCardApplet();
    }

    private JavaCardApplet() {
       // register();

        hello = new HelloWorld();
        svc=new RMIService((Remote) hello);
        disp = new Dispatcher((short)1);
        disp.addService(svc, Dispatcher.PROCESS_COMMAND);
    }

    public static void install(byte[] buf, short ofs, short len){

        (new JavaCardApplet()).register();
    }

    public void process(APDU apdu) {
        //Insert your code here
     disp.process(apdu);
    }
}

IDE不會在編輯器上顯示任何錯誤或警告，但是，我嘗試構建代碼：調試控制台中顯示了以下內容：
