Exceptions doesn't work in Extended Length APDU

Post by hosseinpro » Sat Jul 15, 2017 5:55 pm

Hi

I wrote an applet that receives an extended length APDU.
For short command APDU, if applet throws an exception the card sends error sw.
But for extended length APDU, if applet throws an exception, the card sends 9000 instead of error!!

I test this simple code:

Code: Select all

   public void process(APDU apdu)
   {
      if(selectingApplet()){
         return;
      }
      
      ISOException.throwIt(ISO7816.SW_INS_NOT_SUPPORTED);


This is the log of short and long (extended length) APDUs:

Code: Select all

>> /send 002000800431323334
>> 00 20 00 80 04 31 32 33 34
<< 6D 00   Instruction code not supported or invalid

You have to use ENVELOPE COMMAND to send extended length APDU when using protocol T=0.
sense and simplicity

I use Java card Emulator, so I changed the protocol to T1 and it works without any change!

Thanx
