the byte array can not receive the data in data field of APDU command
Posted: Thu Nov 19, 2015 7:37 am
I have a question when writing a simple java card applet.
Here is my code:
when I send APDU command
>> /send 00010000051122334455
The array buf can not receive the data in the data field of APDU command. I mean it can only receive the first five bytes(0001000005) but the last five bytes(1122334455).
Why this happened? Am I making any mistakes?
Here is my code:
Code: Select all
public class javacard_applet extends Applet
{
public static void install(byte[] bArray, short bOffset, byte bLength)
{
new javacard_applet().register(bArray, (short) (bOffset + 1), bArray[bOffset]);
}
public void process(APDU apdu)
{
if (selectingApplet())
{
return;
}
byte[] buf = apdu.getBuffer();
switch (buf[ISO7816.OFFSET_INS])
{
case (byte)0x01:
break;
case (byte)0x02:
break;
default:
ISOException.throwIt(ISO7816.SW_INS_NOT_SUPPORTED);
}
}
}
when I send APDU command
>> /send 00010000051122334455
