Java 6: javax.smartcardio - can't get CPLC

Question

Hello! I have a problem - can't get CPLC with classes from javax.smartcardio (get SW=6a88), but I easily get it with com.sun.javacard.apduio classes from Java Card Kit 2.2.2.
Here the test code for javax.smartcardio :
import java.util.List;
import javax.smartcardio.*;
public class TestSmartCardJSE60
public static void main(String[] args)
  try
   TerminalFactory tf = TerminalFactory.getInstance("PC/SC", null);
   CardTerminals cts = tf.terminals();
   List<CardTerminal> avaiableTerminals = cts.list();
   CardTerminal ct = avaiableTerminals.get(0);
   Card card = ct.connect("*");
   try
    CardChannel channel = card.getBasicChannel();
    CommandAPDU capdu = new CommandAPDU(0x80, 0xCA, 0x9F, 0x7F);
    ResponseAPDU res = channel.transmit(capdu);
    System.out.printf("%s%n", res);
   finally
    card.disconnect(true);
  catch(Exception e)
   e.printStackTrace();
}And here the same for com.sun.javacard.apduio
import com.sun.javacard.apduio.*;
public class TestSmartCardJCK222
public static void main(String[] args)
  try
   CadClientInterface cad = CadDevice.getPCSCClientInstance(0);
   cad.powerUp();
   try
    Apdu capdu = new Apdu();
    capdu.command[Apdu.CLA] = (byte) 0x80;
    capdu.command[Apdu.INS] = (byte) 0xCA;
    capdu.command[Apdu.P1] = (byte) 0x9F;
    capdu.command[Apdu.P2] = 0x7F;
    cad.exchangeApdu(capdu);
    System.out.printf("%s%n", capdu);
    capdu.setLe(0x2D);
    cad.exchangeApdu(capdu);
    System.out.printf("%s%n", capdu);
   finally
    cad.powerDown(true);
  catch(Exception e)
   e.printStackTrace();
}I run both tests under WindowsXP SP3 with ORGA ECO5000 Usb and JCOP21 smart card.
What is my problem? Actualy I want to use javax.smartcardio for my application, because classes from that package more useful than com.sun.javacard.apduio;
Any ideas?

Answer 1

You're missing the Le byte, since you're expecting data back. Try it.
