Hi Jean-Pascal,
The code for writing a simple string on a smart card is indeed very simple.
What is more complex, is that you must prepare the card for it. You either
need a javacard with an appropriate applet on it, or an ISO7816-compatible
card with an appropriate file structure on it.
When your card is ready, you write your applciation either by using special
CardServices provided by the card manufacturer, or, to keep your app simple,
with the PassThruCardService included in OCF.
We here at the university are using STARCOS cards from Giesecke&Devrient
(http://www.gdm.de/starcos). For my experiments, I only use the
PassThruCardService.
Here is some sample code, which simply selects a file, just to show you how
to send a command to the card :
import opencard.core.service.SmartCard;
import opencard.core.service.CardRequest;
import opencard.opt.util.PassThruCardService;
import opencard.core.util.OpenCardPropertyLoadingException;
import opencard.core.service.CardServiceException;
import opencard.core.terminal.CardTerminalException;
import opencard.core.terminal.CommandAPDU;
import opencard.core.terminal.ResponseAPDU;
public class scard
{
public static void main(String[] args)
{
System.out.println("Starting OpenCard...");
try
{
SmartCard.start();
System.out.println("Started! Waiting for card...");
CardRequest cr=new
CardRequest(CardRequest.ANYCARD,null,PassThruCardService.class);
SmartCard sc=SmartCard.waitForCard(cr);
PassThruCardService
serv=(PassThruCardService)sc.getCardService(PassThruCardService.class,true);
System.out.println("Card inserted and pass-through service
instatiated.");
//You have your card and service ready
here--------------------------------
byte[] arr=new byte[7];
arr[0]=(byte)0x00; //This is a SELECT APDU
arr[1]=(byte)0xa4;
arr[2]=(byte)0x02;
arr[3]=(byte)0x0c;
arr[4]=(byte)0x02;
arr[5]=(byte)0x10;
arr[6]=(byte)0x20;
CommandAPDU com=new CommandAPDU(arr);
System.out.println("Sending APDU... (Select file)");
ResponseAPDU resp=serv.sendCommandAPDU(com);
System.out.println("Response: "+resp.toString());
//---- Other commands may follow now
----------------------------
SmartCard.shutdown();
System.out.println("OCF shut down.");
}
catch(Exception e)
{
System.out.println("Exception: "+e.getMessage());
return;
}
}
}
Hope this helps all beginners.
Later,
