Hi Park HeeJin You have done a good work ! Its really appriciatable !Cheers
pramod! i too have the same probs what u had .....could u plz help me with that?thx,
The Sun kit runs without a card but simulates a card with the powerup;powerdown; commands.
There isn't a gui or prompt to send apdu commands to the card, that's purpose of appending the apdu commands for your applet in the script file.
With JC 2.2 you use OCF with the reference implementation if you want a gui.
I am running the sample wallet program.
through scriptgen i got wallet.scr file
i added two line at top of the wallet.scr file
powerup;
// Select the installer applet
0x00 0xA4 0x04 0x00 0x09 0xa0 0x00 0x00 0x00 0x62 0x03 0x01 0x0c 0x06 0x7F;
I got this(0xa0 0x00 0x00 0x00 0x62 0x03 0x01 0x0c 0x06) from wallet.opt file i.e. wallet applet id
i appended powerdown;
In one command window i am starting cref
c:\wallet>cref -o wallet.out
another window i am executing apdutool
c:\wallet\javacard>apdutool wallet.scr

You won't be prompted to input any data. How would it know what to prompt you for ? ! ! ! Who would prompt ? The card or the reader ? ! ! !
You need to read the specifications and programming guide to understand that communcation to the CAD is thru a series of APDU commands. Nowhere does it mention any user prompted data input !
You have to write middleware to do any prompting.
So to send a debit amount you would send an APDU command to the applet.
Look at the programming guide and you'll see how to send APDU commands. Look at the various .scr files provided in the samples to see how APDU commands are sent.
