Hi,
I'm a beginner with ocf and have a problem:
In our system you enter the smart-card-PIN in a window on your PC
instead of the card reader. And
now our code should be changed in that way, that you have to enter the
PIN into the card reader
directly. What do I have to do?
our accessCard() includes the following:
...
try {
// Get the card service for reading data
cfs = (FileAccessCardService)
m_sc.getCardService(FileAccessCardService.class, true);
m_root = new CardFile(cfs);
if (m_bTrace)
System.out.println("DiCardAccess mounted root " + m_root + "
successfully");
} catch (Exception e) {
m_sc = null;
m_root = null;
throw new DiCardException(DiCardException.DIA_ERR_CARD_ACCESS, "Card
cannot be
accessed");
}
try {
// Register DiCHVDialog
DiCHVDialog dialog = new DiCHVDialog();
cfs.setCHVDialog(dialog);
} catch (Exception e) {
throw new DiCardException(DiCardException.DIA_ERR_INTERNAL,
"Registering
DiCHVDialog");
}
...
and the DiCHVDialog looks like this:
import java.awt.Frame;
import java.awt.Dimension;
import com.ibm.opencard.handler.IDDialog;
import opencard.core.service.CHVDialog;
public class DiCHVDialog implements opencard.core.service.CHVDialog {
public DiCHVDialog() {
super();
}
/**
* getCHV method comment.
*/
public String getCHV(int arg1) {
Frame frame = new Frame("");
frame.setVisible(false);
IDDialog dialog = new IDDialog(frame, "PIN Verification", "Please enter
your personal PIN ", arg1);
Dimension dim = frame.getToolkit().getScreenSize();
dialog.setSize(dim.width / 3, dim.height / 3);
dialog.setLocation(dim.width / 2 - dim.width / 6, dim.height / 2 -
dim.height / 6);
dialog.show(); // popup dialog for PIN entry, wait for CHV
frame.dispose(); // kill the frame
String pin = dialog.pin();
if ((pin != null) && (pin.length() == 0))
// empty password
pin = null; // not allowed
// 4 digit PIN must be extended to 8 digits
if (pin != null)
while (pin.length() < 8) {//for (int i = pin.length(); (i < 8); i++) {
pin = pin + "0";
}
return pin;
}
}
Thanks for helping me,
