Hello everyone,

I am having the following error when debugging: 6C 0B

But the INS is: (byte) 0x00;

I understand that the APDU is:
CLS | INS | P1 | P2 | LC | LE

CLS: 80
INS: 00
P1: 00
P2: 00


// debug JCIDE IDE :

>> /select 010203040506070809070707 <-- AID
>> 00 A4 04 00 0C 01 02 03 04 05 06 07 08 09 07 07 07 00
<< 90 00 <-- OK


>> /send 80000000
>> 80 00 00 00
<< 6C 0B Unknown Error <-- error




Here is my source ...

package br.com.helloworld;

import javacard.framework.*;



public class HelloWorldJC extends javacard.framework.Applet {

// CLA Byte

final static byte HELLO_CLA = (byte) 0x80;
private static final byte[] helloWorld = { (byte) 'H', (byte) 'e',

(byte) 'l', (byte) 'l', (byte) 'o', (byte) ' ', (byte) 'W',

(byte) 'o', (byte) 'r', (byte) 'l', (byte) 'd', };

private static final byte INS_HELLO = (byte) 0x00;



public static void install(byte[] bArray, short bOffset, byte bLength) {

(new HelloWorldJC()).register(

bArray,

(short) (bOffset + 1),

bArray[bOffset]);

}



public void process(APDU apdu) {

byte[] buffer = apdu.getBuffer();

if ((buffer[ISO7816.OFFSET_CLA] == 0)

&& (buffer[ISO7816.OFFSET_INS] == (byte) (0xA4)))

return;



if (buffer[ISO7816.OFFSET_CLA] != HELLO_CLA)

ISOException.throwIt(ISO7816.SW_CLA_NOT_SUPPORTED);



switch (buffer[ISO7816.OFFSET_INS]) {

case INS_HELLO :

getHello(apdu);

return;

default :

ISOException.throwIt(ISO7816.SW_INS_NOT_SUPPORTED);

}

}


private void getHello(APDU apdu) {


short le = apdu.setOutgoing();
short totalBytes = (short) helloWorld.length;
apdu.setOutgoingLength(totalBytes);

apdu.sendBytesLong(helloWorld, (short) 0, (short) helloWorld.length);

}

}

Hi,

I Solved the problem :


short readCount = apdu.setIncomingAndReceive();
[b] Util.arrayCopyNonAtomic(helloWorld,(byte)0,buffer,ISO7816.OFFSET_CDATA,(short)helloWorld.length);[/b]
apdu.setOutgoingAndSend(ISO7816.OFFSET_CDATA,(short)helloWorld.length);

break;


Thanks !

Send the command with LE as 0x0B;


SW = 0x6Cxx
Means that the command shall be sent with LE = xx.

Hi, UNKNwYSHSA

Thanks !

Please use the Code tag for your APDU request/response and codes to make it easier for forum members to read.

Thanks.

Hi,

Ok, sorry !
