java - PCSC 在 linux 上不返回任何内容，读卡器已连接

Question

我正在尝试使用 PCSC 框架读取卡片。但它根本不返回任何内容。

import java.util.List;
import javax.smartcardio.*;

public class Blog {
 public static void main(String[] args) {
  try {
   // Display the list of terminals
   TerminalFactory factory = TerminalFactory.getDefault();
   List<CardTerminal> terminals = factory.terminals().list();
   System.out.println("Terminals: " + terminals);

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

   // Connect wit hthe card
   Card card = terminal.connect("*");
   System.out.println("card: " + card);
   CardChannel channel = card.getBasicChannel();

   // Send Select Applet command
   byte[] aid = {(byte)0xA0, 0x00, 0x00, 0x00, 0x62, 0x03, 0x01, 0x0C, 0x06, 0x01};
   ResponseAPDU answer = channel.transmit(new CommandAPDU(0x00, 0xA4, 0x04, 0x00, aid));
   System.out.println("answer: " + answer.toString());

   // Send test command
   answer = channel.transmit(new CommandAPDU(0x00, 0x00, 0x00, 0x00));
   System.out.println("answer: " + answer.toString());
   byte r[] = answer.getData();
   for (int i=0; i<r.length; i++)
    System.out.print((char)r[i]);
   System.out.println();

   // Disconnect the card
   card.disconnect(false);
  } catch(Exception e) {
   System.out.println("Ouch: " + e.toString());
  }
 }
}

输出:

run-single:
Terminals: []
Ouch: java.lang.IndexOutOfBoundsException: Index: 0
BUILD SUCCESSFUL (total time: 4 seconds)

通过使用其他工具它可以工作，但无法弄清楚为什么不显示 Java 代码？

我在这里找到了另一种解决方法

Accessing javax.smartcardio from Linux 64 bits

I think I found a workaround for this as I just had a similar problem. In a bugreport from ubuntu it says that the javax.smartcardio library searches for the PC/SC library in the wrong directory.

So running my app with the setting as below worked for me

-Dsun.security.smartcardio.library=/usr/lib/x86_64-linux-gnu/libpcsclite.so
