Java Card

Sorry All ... but I stard a new topic on one of my old subject.

Hi everybody ... Acutally I try to read the IMSI (serial number of a gsm sim card), I've moved to the JAVA 1.6 release, because AFAIK, the is the only version that support smartcard I/O.

Actually I use this code to access my card:


------------- CUT HERE -------------------

try {
         List<CardTerminal> terminals = factory.terminals().list();
         System.out.println("Terminals: " + terminals);
    // Get the first terminal
         CardTerminal terminal = terminals.get(0);
    // * *******************************************************************************
    // *
    // * Establish a connection with the card
         Card card = terminal.connect("T=0");
         System.out.println("card: " + card);
         byte[] x = { (byte)0x00,(byte)0x00,(byte)0x00,(byte)0xc1 };
         
         byte Command[]; 
         Command=new byte[4];

         Command[0]=(byte)0xCA;
         Command[1]=(byte)0xA0; // calculator
         Command[2]=(byte)0x03;
         Command[3]=(byte)0x03; 
         
         
         CardChannel channel = card.getBasicChannel();
         ResponseAPDU r = channel.transmit(new CommandAPDU(Command));

I think that I've to know the right value for the Command byte.
Any suggestion?!?!
