Here is the PCSC sample in Java language I promised in PC/SC sample in different languages.
Since Java 1.6 the JRE includes the package javax.smartcardio which was defined in the JSR 268. No need to compile additional source code.
For the example I used Eclipse Galileo and the Java 1.6 provided by Apple on a Mac OS X Snow Leopard (10.6.4).
Nothing special to add. The major advantage here is that the wrapper is included in the runtime. So you do not have to install much on a system before you can use your program, just the JRE :-)
Installation
Since Java 1.6 the JRE includes the package javax.smartcardio which was defined in the JSR 268. No need to compile additional source code.
For the example I used Eclipse Galileo and the Java 1.6 provided by Apple on a Mac OS X Snow Leopard (10.6.4).
Source code
import java.util.List;
import javax.smartcardio.*;
public class Blog {
public static void main(String[] args) {
try {
// Display the list of terminals
TerminalFactory factory = TerminalFactory.getDefault();
List<CardTerminal> terminals = factory.terminals().list();
System.out.println("Terminals: " + terminals);
// Use the first terminal
CardTerminal terminal = terminals.get(0);
// Connect wit hthe card
Card card = terminal.connect("*");
System.out.println("card: " + card);
CardChannel channel = card.getBasicChannel();
// Send Select Applet command
byte[] aid = {(byte)0xA0, 0x00, 0x00, 0x00, 0x62, 0x03, 0x01, 0x0C, 0x06, 0x01};
ResponseAPDU answer = channel.transmit(new CommandAPDU(0x00, 0xA4, 0x04, 0x00, aid));
System.out.println("answer: " + answer.toString());
// Send test command
answer = channel.transmit(new CommandAPDU(0x00, 0x00, 0x00, 0x00));
System.out.println("answer: " + answer.toString());
byte r[] = answer.getData();
for (int i=0; i<r.length; i++)
System.out.print((char)r[i]);
System.out.println();
// Disconnect the card
card.disconnect(false);
} catch(Exception e) {
System.out.println("Ouch: " + e.toString());
}
}
}
Output
Terminals: [PC/SC terminal Gemplus GemPC Twin 00 00]
card: PC/SC card in Gemplus GemPC Twin 00 00, protocol T=1, state OK
answer: ResponseAPDU: 2 bytes, SW=9000
answer: ResponseAPDU: 14 bytes, SW=9000
Hello world!
Conclusion
Nothing special to add. The major advantage here is that the wrapper is included in the runtime. So you do not have to install much on a system before you can use your program, just the JRE :-)
