Is there a way to naming a card reader?

Question

Hi everyone!
I’m new in Java, especially Javacard. I’m using GEMPC Twin smart card reader, GemXpresso211 PK_IS card and OCF1.2 for off-card application. I was able to run sample javacard program and obtain information about registered terminals from opencard.properties file. Here is the sample code:
import java.util.Enumeration;
import java.util.Properties;
import opencard.core.service.CardServiceException;
import opencard.core.service.SmartCard;
import opencard.core.terminal.CardTerminal;
import opencard.core.terminal.CardTerminalException;
import opencard.core.terminal.CardTerminalRegistry;
import opencard.core.util.OpenCardPropertyLoadingException;
* A sample providing information about the registered terminals.
* Please <B>Note</B> that the set of <i>registered</i> terminals
* may differ from the set of terminals that is <i>physically attached</i>
* to the system.

public class GetTerminalInfos {
  private static final String NAME = "get information about registered terminals";
  private static final char ENDL   = '\n';
  public static void main (String [] args) {
    System.out.println ("------------------------------------------------------------");
    System.out.println ("start use case: " + NAME);
    System.out.println ("");
    try {
      SmartCard.start();
      CardTerminalRegistry ctr = CardTerminalRegistry.getRegistry();
      Enumeration terminals = ctr.getCardTerminals();
      int counter = 0;
      while (terminals.hasMoreElements() ) {
        CardTerminal terminal = (CardTerminal) terminals.nextElement();
        printTerminalInfos(terminal);
        counter++;
      System.out.println ("there " +
        (counter > 1 ? "are" : "is") + " " +
        counter + " terminal" +
        (counter > 1 ? "s" : "") + " installed!");
      SmartCard.shutdown();
    catch (OpenCardPropertyLoadingException plfe) {
      System.out.println ("OpenCardPropertyLoadingException: ");
      System.out.println (plfe.getMessage() );
    catch (ClassNotFoundException cnfe) {
      System.out.println ("ClassNotFoundException: ");
      System.out.println (cnfe.getMessage() );
    catch (CardServiceException cse) {
      System.out.println ("CardServiceException: ");
      System.out.println (cse.getMessage() );
    catch (CardTerminalException cte) {
      System.out.println ("CardTerminalException: ");
      System.out.println (cte.getMessage() );
    System.out.println ("");
    System.out.println ("finished use case: " + NAME);
    System.out.println ("------------------------------------------------------------");
  } // mainHowever, it helps me much in getting the card readers info. Consider following result:

=======================================================
Address:
Name:    OMNIKEY CardMan 5x21-CL 0

terminal.features ():

slot infos:
there is 1 slot present in this terminal!
slot channel available: yes
Slot info:
slot ID: 0
card present: no
there are 4 terminals installed!
finished use case: get information about registered terminals
BUILD SUCCESSFUL (total time: 2 seconds) In simulator mode, I can set up address for each terminal simulator. In case there will be more than 1 card reader installed with the same type, it will be so much helpful if there is a way to set address or “give name” to each card reader. Any idea how to do this? I really need this to finish my final task. Thanks before.

What version of OCF did you use? the latest is at openscdp.org/ocf , others are obsolete.
There is nothing special to configure for normal pcsc readers.
the name of these readers is defined by the reader driver. There is no way to change it.
If you want to give arbitrary name to your readers, use a Hashmap or something like that.
