Load Applet to Java card

hi,
I load A applet to java card. Then i load B applet.
But i want to load if key match then only load A or B applet.
How can i maintain load applet.
I am using Eclipse SDK JCOP31 tool.

thanks for reply.
I am using Eclipse SDK JCOP 31 tools for Java card applet development and loading same into java card.
when loading applet into java card some internal authentication process is handled by JCOP.
But i don't have clear idea about this authentication process.
So can any one explain which algorithm they used for authentication & how they will be setting the Key for the same.
If i want to change the algorithm and key in JCOP how i can proceed?
Regard,
Senthil

Problem in loading applet into java card.

Hi all,
I have developed an applet using java card development kit 2.2.2 and JDK1.5. The cap file is generated successfully. Am using gpshell to load applet into the card but am getting an error saying "Error : load_applet() returns 0x80206A80 (6A80: Wrong data / Incorrect values in command data.)" . Can anyone please tell me where am wrong. My install file contains :

Hi all,
Sorry above i forgot to mention the java card am using. It is JCOP21 and in its datasheet its mentioned that it specification needed are javacard development kit 2.2.1, is that may be the reason for this error?
Thanks in advance

Java application communicate with java card applet without java card

Can I write java application to communicate with java card applet without using java card?
Can I send APDU to java card applet on computer(not install in java card)? If it's not, how can I write?
Best Regard,
Thanawan

Your JCOP simulator implements a JCVM/JCRE according
to specs. The CREF does that same thing excepts it's
only simulates the API without crypto or third party
applets. JCOP simulator is more then that. They are using thesame_ codebase for simulator and for oncard JCVM. Basically you are dealing with the same environment in both cases.

Error 6A80 when loading applet to my card

Hi everyone,
First, please excuse me for my bad english, i'm french.
So, i'm trying to upload an applet to my eGate CyberFlex 32K JavaCard, but some code lines causes 6A80 error.
Here is my applet source (it's just a first test ;-) ) :
package applet;
import javacard.framework.*;
public class TheApplet extends Applet {
    private final static byte CARD_CLA      = (byte)0x80;
    private final static byte INS_TEST      = (byte)0x02;
    private final static byte PIN_TRY_LIMIT = (byte)0x03;
    private final static byte MAX_PIN_SIZE = (byte)0x04;
    final static short SW_PIN_VERIFICATION_REQUIRED = 0x6301;
    protected byte[] name = {'T', 'e', 's', 't'};
    private OwnerPIN pin;
    protected TheApplet() throws PINException {
        this.register();
        pin = new OwnerPIN(PIN_TRY_LIMIT, MAX_PIN_SIZE);
        byte[] pins = {(byte)0, (byte)0, (byte)0, (byte)0};
        pin.update(pins, (short)0, MAX_PIN_SIZE);
        byte i = pin.getTriesRemaining();
        //pin.check(pins, (short)0, MAX_PIN_SIZE); // CAUSES 6A80 error when loading
    public static void install (byte[] bArray, short bOffset, byte bLength)
    throws ISOException {
        new TheApplet();
    public boolean select() {
        /*if (pin.getTriesRemaining() == 0) { // CAUSES 6A80 error too..
            return false;
        return true;
    public void process(APDU apdu) throws ISOException, PINException {
        byte[] buffer = apdu.getBuffer();
        if (selectingApplet() == true) {
            return;
        if (buffer[ISO7816.OFFSET_CLA] != CARD_CLA) {
            ISOException.throwIt(ISO7816.SW_CLA_NOT_SUPPORTED);
        if (buffer[ISO7816.OFFSET_INS] != INS_TEST) {
            ISOException.throwIt(ISO7816.SW_INS_NOT_SUPPORTED);
        //pin.isValidated(); // Causes error.
        apdu.setOutgoing();
        apdu.setOutgoingLength((short)name.length);
        apdu.sendBytesLong(name, (short)0, (short)name.length);
}In fact, all access to pin causes error when loading, when commented lines are uncommented, the applet loads successfully.
Do you know what the problem is ?
I'm using JavaCard 2.1.2, and GPshell 1.4.2.
This is the gpshell script :

How to load applet to smart card.

I'm new in smart card world and at this moment try to run examples.
I have java_card_kit-2_2_2-windows and GPShell-1.4.2
I have successfuly run all examples from card kit with use of cref (emulator) and now I whant to run simple example with real card.
I have a card reader: CardMan 3x21 (USB)
In diagnostic tool it shows me card ATR: 3B 69 00 FF 4A 43 4F 50 32 31 56 32 32
Protocol T=0
But I can find this ATR in smartcard_list.txt (http://ludovic.rousseau.free.fr/softwares/pcsc-tools/smartcard_list.txt)
The most closest match
3B 66 00 FF 4A 43 4F 50 33 30
JCOP30 "OP-DI 16k VISA v2 (JCOP30) ORGA"
I suspect that I have JCOP21 ORGA card (from my customer info)
1) When I try to run GPShell HelloInstall.txt the scrip executed until insatll aplet
it writes error messge: "reference data not found..."
2) With apdutool from card kit I cant even connect to card reade...
Could any body sugest me what I should try next?

Hello all!
I gain some progress by my self, but still has questions.
1) Form card manufacturer I get that I have following card:
JCOP 21 v2.2:
ISO7816
JavaCard 2.2.1, GlobalPlatform: 2.1.1
EEPROM: 36kb
RAM: 3kb
2) I can run some scripts with GPShell 1.4.2

load_applet() returns 0x80206A80 (6A80: Wrong data / Incorrect values in command data.)
Does any body nows why this script failed? OR I should write bug report for GPShell ?

How to ensure applet is written in java card?

Hi all,
I have written a java card applet, in which i am using the Biometry API of java card to enroll a fingerprint template in java card. Code is attached below:

Problem :
I have developed this program in Netbeans using java card plug ins. when i am running this program, all the required CAP files and EXP files are generated.
Now, i have to write this applet on java card through a card reader. My card reader is installed in an embedded system GeoAmida with IP 192.133.133.2 and port number 6789.
I have used the following settings for my java card device in Netbeans:
Host : 192.133.133.2
Server URL: http://192.133.133.2:6789/
Card Manager URL: http://192.133.133.2:6789/cardmanager/
HTTP port: 6789
The output shows me that Instances of this program has been successfully has been created on java card.
But the problem is how can i ensure that my applet is been successfully installed on the java card?
The code of host application program, accessing the developed java card applet is given below (it is written in C):
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <smartcard.h>
int main()
     int ret, i, smartcard;
     unsigned char applet_id[100], apdu_len, apdu[300],response[300]={0};
     smartcard_info *context;
     smartcard=CONTACTLESS;
     //smartcard=CONTACT_BOT;
     if((context = smartcard_init(smartcard)) == NULL){
          printf("Smartcard Initi. Failed\n");
          return 0xBB;
     /* checking for smartcard */
     while (1){
          if(ret=smartcard_is_present(context, smartcard)!=0)
               sleep(1);
          else
               break;
     printf("Selecting Applet \n");
     i = 0;
     applet_id[i++]=0x00; applet_id[i++]=0xA4; applet_id[i++]=0x04; applet_id[i++]=0x00; applet_id[i++]=0x06;
     applet_id[i++]=0xA9; applet_id[i++]=0xBF; applet_id[i++]=0xA2; applet_id[i++]=0xB6; applet_id[i++]=0xB1; applet_id[i++]=0x3E; applet_id[i++]=0x7F;
     if ((ret=smartcard_select_applet(context, smartcard, applet_id, i))!=0){
          printf("select applet failed %02x\n",ret);
          return ;
     printf("Applet Selection Success \n");
#if 1
     i=0;
     apdu[i++]=0xCF; apdu[i++]=0x10; apdu[i++]=0x04; apdu[i++]=0x04; apdu[i++]=0x7F;
     //apdu[i++]=0x3F; apdu[i++]=0x00;
     apdu_len = i;
     printf("Sending APDU command\n");
     if ((ret=smartcard_apdu(context, smartcard, apdu, apdu_len, response))!=0){
          printf("apdu failed %d\n",ret);
          //return;
     }else
          printf("APDU Success\n");
     //printf("\n");
#endif
     smartcard_deinit(context);
     return 0;
}The output of this program is showing me that applet is been successfully selected, but APDU selection failed. Please solve this problem as soon as possible, because my project is deadline is not very much far.
Thanks in advance.

Hi Shane,
I am getting error 6a86 which means that value of P1 is less than 1 or more than 8, and we have to change its value to any in between 1 to 8. I did that also but error still remains :(
Please tell me what is reason behind this error. And, i'll try out your previous solution today, Thanks for it.

Java Card & X 509 certificates

Hi,
i have a question about using Java Card with X.509 Certificates (including Attribute Certificates RFC 3281).
I already have some experience with JC 2.1.1. I have implemented applets for storing files and retrieving them (deployed on card using GemXplore Developer Kit)
and then managed the communication between off card application using the OCF 1.2.
But that was back in 2004. From what i see now OCF has been abandoned.
What i want to implement now is to load Certificates on Java Card (and store files as well).
I read that in order to manage Certificates, i have to use a PKCS 11 API (like Bouncy Castle or IAKI). Does this substitute OCF? I remember OCF was complimentary to PKCS 11.
And if it does, can i use such API to read and write other files except from Certificates? Finally does it treat Attribute Certificates (AC) same as PKI Certs?
I case you need clarifications, i ll be happy to provide. Thank you in advance
John

I think you can store keys and data to sign in the same applet. data is just data, it won't auto interfere.
about javacard 3, I think this is a very polemic subject. To feed the troll, I'll say that I'm working in a smart card company that has done cards for many years. since the beginning, i can say. All my colleagues and I think that javacard 3 is an evil. APDUs ARE card-ish and a good thing for such small CPUs. Javacard 3 has been made by sun under pressure of telcos that don't want complicated things, and are big specification fans, that never wrote a line of code. Javacard 3 will put a big overhead on card response time: as of now, there are many abstractions levels to cross to execute bytecode, and servlets and (dont know what will replace apdus) will increase transaction times.
cards are cards, not web servers. for us, public transportaton sectors guys, javacard 3 is a frankenstein. we want speed and low level access. we don't care about J2EE.
just don't tell me about the increased mem and power of new cards. How much will they cost? A javacard is already expensive, they will not get cheaper, and this will not help spreading javacards.
people working in the J2EE world will code for javacard 3 like they do for mainframes. They will require more powerful card just because they're too lazy to code a correct embedded software . Can you imagine that? Maybe javacard 4 will require a heatsink on cards.
this is a very personal opinion of course ;)

NetBeans java card platform

Dear All,
I need a java card simulator to debug my java card applet code.
I try to use Java Card Platform on NetBeans IDE 7.1 for debugging purpose. After successfully building the applet and loading it onto the simulated card environment I try to select the applet instance using the following command through the Console.
select //aid/3F564379F5/00279CD982
in response I receive the following error.
"Connection reset by peer: socket write error"
Is anyone using Java Card Platform for debugging? I would be very happy to hear how to resolve this problem.
Thanks in advance!
Cheers!

Hello Rohit,
If you download the Java Card Development Kit (http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javame-419430.html#java_card_kit-2.2.1-oth-JPR)
you will have a set of sample java card applets to use.
You can use JPShell to download the cap files(compiled applet) onto the card and send ADPU to the card to see if you get correct response.
Following link provides all the information to set up the environment and start developing java card applets using NetBeans IDE and GPShell.

I hope this can help.
MehmetI already have , Netbeans 7.1 and now i have gpshell 1.4.4 ,i think netbeans is capable to making .cap file, did you mean that with use of gpshell i can connect with java card through reader? gp shell would work stand alone or we need to set this to netbeans? i read the link which u passed to me, it seems very good but "it seems very tough to implement" . HELL IS WAITING FOR ME... KIDDING DEAR,
one last thing, anything other than net beans { here we create applet and it automatically create cap file} and gp shell are require to load applet onto the card? OR these is enough to implement wholo java card application- I asked this because i get the term JCOP and etc when i read uploading applet to card.
anyways thanks for your help.

How to evaluate an Java Card OS

Hi all.
Image that you have a card with java OS. How will you do to ensure that it is a real java OS.
I think that i only can check by writing applet (use Java Card API Spec).
Can you suggest me which i need to do to sure that all the function of OS are good, what are really important component..
i think you understand my issue.
Longing for your answer.
Thanks

I profit of this topic to ask some questions relating to JCOS :-)
Recently, I've heard about JCOS development from one of my friend working on this project. Supposing that he has a complete JCOS codes. What will he do is to compile this project and assemble all the compiled codes to produce a hex file. Then, he load this hex file onto the smartcard for the next step (mass perso production).
As he described (in fact his company is working such a project), this OS includes from the lowest level (HAL for example, implemented in C) to the highest one (application layer). I'm wondering, this kind of OS loading will leads to the fact that, his OS will be loaded onto the EEPROM of the smartcard. As far as I understand, OS will normally be loaded onto the ROM, the OS developper will give out the mask of their OS to IC manufacturer in order to load their OS on ROM in mass production. This makes me surprised because so far, I have always thought that, OS must be loaded onto ROM, not onto EEPROM as he told me (of course, some high level layer of OS can be loaded onto EEPROM).
Is there anybody here who has been working on JC OS dev to clarify me on this point? And if possible, can you tell something about the differences between OS loading on EEPROM and OS loading on ROM from your point of view?
Best regards,
J-D

The Installer and the Applet Deletion Manager are implemented in the JCRE and GlobalPlatform. On-card the Card Manager manages the content management, communication and the related security. JCRE specifies how it has to handle installation and deletion, but leaves room for different implementations. To the outside world, on a GP card, the Installer/ADM is the Card Manager with a specific AID.
Installer and ADM are optional. For instance a Java Card Static product does not need an Installer/ADM.
JCOP cards have the Installer/ADM fully implemented. It uses the GP functionality. The CM has to be selected to install or delete a package/applet.

A question about design of Java Application on java card.

Hi every one,
I have a question about design of Java applet on java card,
There is an application on my card that it is not java card, it include a DF and some EF under DF, I would like to know if I want to have this application on java card ,how can I design DF and EF on java card ,I mean is there any relation between DF,EF with applet and file? for example can I say DF is same as applet and EF is same as file?
I'll appreciate for any help .
yours sincerely,
orchid

hi
you can write a java class for DF.
an instance of DF class have some EF objects.
for example,
samples/com/sun/javacard/samples/JavaPurse/CyclicFile.java
implements ISO 7816 CyclicFile ( EF )

What are the steps for installing applet on real card?

Hi,
It has been a month that I am fighting to install applet on java card and now I am really confused where I am going wrong?
I have 3 sets of cards --
1 ) Gemalto (no specific name known) - ATR is --3B 6D 00 00 80 31 80 65 B0 84 01 00 AC 83 00 90 00
As gemalto customer support doesn't know about this card so I was unable to find its card manager AID. The standard Game expresso card manager AID does not work with this card.
2 ) Pre- Personalized NXP card-- This is JCOP 3.1 complaint pre-personalized card but i am not able to perform Init- Auth using a GPShell script. I have key but some how GPshell script does not work.
3) NXP Smart MX family cards(IBM JCOP v2.2 41) -- These cards are not pre-personalized. So what i am supposed to do with these cards so that they will be pre-personalized?
I will be really thankful for any kind of reply.
Edited by: Amit_D30 on Jul 28, 2008 4:59 AM

Any ways I got rid of this error as my card was supporting mode 201 of GPShell instead of mode_211.
But even with the mode_201 I am getting error as card cryptogram failed.

So should I try it again or Will my card get blocked? (out of 5-6 tries only one try returned me Card cryptogram failed error in other cases I was getting error as Invalid parameter P1,P2 )

Java Card Tools

Hi All,
Im new to this Forum and even to java cards. I would like to know the proper tools to use for java card development and guidelines. Is there anybody around who could help me in this regard.
Thanks in Advance
Ganesh

Hello,
Tools ?? hmm...
What?
Three basic things about a java card application development is
1. Write a code (you need java card libraries - find them)
2. Compile it (to generate .class files - simple as compiling a normal java code)
3. Convert it (to generate .cap/ .jar / .ijc / .ldr etc etc... - depending on what format you require.) - this a the one you can load on your java card.
How?
There are no generic tools available to do it all.. but of-course there is one. Try to get SIM Alliance Loader. It can compile-convert-load(all three steps).
Hope this help. Revert if you need more info on this.
