Java智能卡-阅读Scosta智能卡

Question

我试图通过java 阅读印度政府标准的“Scosta”智能卡，我使用的代码是

package com.example.smartcardreader;

import java.util.List;

import javax.smartcardio.ATR;
import javax.smartcardio.Card;
import javax.smartcardio.CardChannel;
import javax.smartcardio.CardException;
import javax.smartcardio.CardTerminal;
import javax.smartcardio.CommandAPDU;
import javax.smartcardio.ResponseAPDU;
import javax.smartcardio.TerminalFactory;

public class SmartCardReader {

 public static void main(String[] args) {

        try{

            // show the list of available terminals
            TerminalFactory factory = TerminalFactory.getDefault();

            List<CardTerminal> terminals = factory.terminals().list();

            System.out.println("Terminals: " + terminals);

            // get the first terminal
            CardTerminal terminal = terminals.get(0);

            // establish a connection with the card
            Card card = terminal.connect("*");
            System.out.println("card: " + card);

            // get the ATR
            ATR atr = card.getATR();
            byte[] baAtr = atr.getBytes();

            System.out.print("ATR = 0x");
            for(int i = 0; i < baAtr.length; i++ ){
                System.out.printf("%02X ",baAtr[i]);
            }

            CardChannel channel = card.getBasicChannel();
            byte[] cmdApduGetCardUid = new byte[]{
                        (byte)0xFF, (byte)0xCA, (byte)0x00, (byte)0x00, (byte)0x00};

            ResponseAPDU respApdu = channel.transmit(
                                                new CommandAPDU(cmdApduGetCardUid));

            if(respApdu.getSW1() == 0x90 && respApdu.getSW2() == 0x00){

                byte[] baCardUid = respApdu.getData();

                System.out.print("Card UID = 0x");
                for(int i = 0; i < baCardUid.length; i++ ){
                    System.out.printf("%02X ", baCardUid [i]);
                }
            }

        card.disconnect(false);

        } catch (CardException e) {
            e.printStackTrace();
        }
    }

}

我正在使用eclipse在Mac机器上进行开发。当我运行这段代码时，它给了我异常，因为它无法读取终端。我有一个USB读卡器，也插入了智能卡到它。你能指出我到底哪里出错了吗？提前谢谢。

这可能与您的问题无关，但是在Mac上使用64位版本的javax.smartcardio似乎严重破坏了软件包java7。您可以在这个博客帖子和这个错误报告中找到更多的信息。您还可以查看开源项目[医]心脏，它试图解决javax.smartcardio包的问题。
