In JavaCard applet, you can do like this:

Code: Select all

case (byte)0x02:
            byte temp[] = new byte[(short)20];
            temp[(short)(temp.length -1)] = (byte)0x66;
            Util.setShort(buf, (short)0, (short)temp.length);
            Util.arrayCopy(temp, (short)0, buf, (short)2, (short)temp.length);
            apdu.setOutgoingAndSend((short)0, (short)(2 + temp.length));
