hi
i've the same problem. i've found this solution, but you need download a JCE Provider that allow you to read the explorer certificate store.
You can try this one: https://download.assembla.se/jceprovider/
and the code:
import se.assembla.*;
public class Listcerts {  
     public static void list() throws Exception{
          java.security.Security.insertProviderAt(new se.assembla.jce.provider.ms.MSProvider(), 2);
          KeyStore ks = KeyStore.getInstance("MSKS","assembla");
          ks.load(null,null);
          X509Certificate cert=null;
          String alias=null;
          int count=0;
          for (java.util.Enumeration e=ks.aliases();e.hasMoreElements();){
                    alias=(String)e.nextElement();
                    cert=(X509Certificate)ks.getCertificate(alias);
                    System.out.println("\n Certificado alias"+alias+":");
                    System.out.println(cert);
               count++;
          System.out.println ("NUM CERTS="+count);
now, i need the same solution for Firefox browser XP
good luck
