如何将JavaCard程序包添加到JavaCard小程序？

Question

I am trying to build a simple Hello world JavaCard applet.I am using NetBeans IDE.

I am following this tutorial.

Here is my code:

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);
    }
}

The IDE doesnt show any error or warning on the editor, but WHen I try to build the code: The foloowing things display in the debug console:

Note :NetBEans IDE has the JavaCard Plugin Installed.

Answer 1

Add the api_classic.jar library and its export path to the libraries of your project manually. This file is exist under this path:

<NetbeansInstalledDirectory>\\javacard\\JCDK3.0.2_ConnectedEdition\\lib

Step by step for beginners:

And now, try to build it again.
