Java Card ROM Applets

Hi
I need to develop Java Card ROM Applets. I need to write native C Code for the Card.
I read in forums that ROM Applets can only be loaded by Vendors. I am the Vendor.
How can I write, compile and test native code for Java Card?
I didn't find any support in Java Card Development Kit downloaded from Sun. Does it have support?
Or is there any other Software kit which supports development of ROM Applets?
Thanks
Abheesh

Most OS providers offer a so called custom masking process, where they merge your applications with the OS into ROM. For instance for JCOP @ NXP, you choose the mask (e.g. JCOP v2.4.1), provide the Java class files and Java Card export files and AIDs. They have an internal tool which created a custom mask where your application source code is residing in ROM. All you need to do now is to instantiate and personalize your application.
Advantages
- Free EEPROM
- Shorter personalization as applications do not need to be loaded
- ROM read is fast than EEPROM read --> better performance as code is read all the time
- ROM cannot as easy be attacked by e.g. light attacks
Disadvantages
- Long lead time of 4 - 6 weeks to produce the mask
- Volume needs to be ordered (2 to 3 wafers minimum = ~10k ICs)
- Dependent on the OS provider <-- compared to loading in EEPROM

Why Applet in the Java Card?

I'm studying the Java Card and GP. I have one question which just hit my head.
Why did the Java Card choose Applets? There are applications, servlets, and so on which can be developed using Java technology.
Does anyone know?
Thanks,
Julie.

No, Java Card applets run on the card. What runs off the card can be ANY language because that's what called middleware. It sits in the middle of the OS and the CAD. PCSC is a middleware. It's written in C. Java Cards don't know anything about an OS or middleware because all communications is to a CAD.
As far as client side Java, that can be a Java Application, or a Java Applet for browsers.

Java Card File System ...Please reply

Hi all ,
I am working on Java Card technology for last one year . Presently I am facing some problem regarding some file concept of java card .
I know that Java Card 2.1 does not support file system . But I want to simulate the file system in java card using applets . i.e . I want to write an application(applet) , which can simulate the EF , DF in smart card . Whenever APDU command is send to the file system applet , it should generate a Elementary file (EF) or dedicated file (DF) etc and store data to that file.
Can I do this type of thing using Java Card ? I am really in doubt .
If you have any idea on this , please let me know your view on this . If you know any open source code for this type of simulated Java card file system , please let me know .
I am desperately looking for a help .
regards
Dibyendu .
you can contact me to this email
[email protected]

dear duran ,
You have written that
"Follow the guidelines for the different supported filesystems on the JC"
But after Java Card version 2.0 , it does not support file system . I am using Java Card 2.1 .
Could please some sample code to my mail Id , so that I can take a look at it .
My mail id is : [email protected]
Please share the idea , as I am really need some help.
Regards ,
Dibyendu.

How do I test a Java card applet with different AIDs on the fly?

... Like sweeping cards from employees in a queue of people lining up in the morning?
When I created my applet, the aid is a fixed value inside the class.
Whenever I wanted to test it with another value, I changed that AID and rerun the applet.
I find it very cumbersome that needs to be rerun and rerun, over and over again.
How do I test the applet easily with any values of AIDs that I'd like to put in, on the fly.
I know I can't simulate the sweeps of card in the applet because I can't have a main method with a signature
of Strings[] args or String[] args. I can only have JUnit to help me out, but still java card doesn't allow either
main(Strings[] args) or TestCase to inherit from.
Thanks
Jack

your question is hard to understand but:
an applet always has one definite AID and you cant change it after install as far as i know
a) you want to test many cards with diffrent AIDs?
->send a list of select commands and check the return values
b)you want one card with the same applet to be available for many AIDs?
->install many dummy applets forwarding the commands to one core applet
c)i think i didnt get your point :/

How to load a java card applet into a java card

Dear All,
I am a novice to java card technology..
I have done some search on how to load a java card applet into a smart card but haven't found a satisfactory answer. I have read about installer.jar and scriptgen tool but I want to load the applet from a java program and not from command line. It would be of great help if somebody can help me out.
If somebody can share a sample program which load a javacard applet(.CAP file) into a smart card, I will be very thankful.
I am able to find some client applications which help us send APDU commands and recieve response APDU's to interact with an applet loaded on to the smart card but not application which actually load the applet.
I have heard of OCF and GP.. some say that OCF technology is outdated and no longer in use.. can somebosy throw some light on this too..
cheers,
ganesh

hi siavash,
thanks for the quick response.. i checked out GPShell as suggested, it looked like a tool by which one can load an applet on to card and send some sample apdu commands... but I want to load the applet from the code.
My application should look something like this.. it will be a swing applicaton where I have a drop down with a list of readers, I select the one desired and then click on "LOAD" after inserting a blank java card, at this point my applet which is stored in my DB should get loaded on to the java card. The next step should be to personalize it where I enter the values for the static variables of my applet and click "PERSONALIZE", at this point all these values should be embedded into APDU commands and sent to the java card for processing.
For achieving this I am yet to find a comprehensive sample or documentation on the net.
Please help...
regards,
ganesh

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 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.

How do I communicate a Java Card applet with a server?

I'm new to Java and Java Card and currently developing a smart card system. I'm not sure what to use on my applet or server, JCSystem or SecureConnection or something else?
If I'm writing a server application, then how do I install it so that I can simulate it with cjre?
Thanks in advance.
p/s: Connection is using TSL.

The flow is like this:
Java Card --> POS terminal -> Server
Yes. I'm using JC3.
Here's what I've achieved so far using SocketConnection
SocketConnection sc = (SocketConnection) Connector.open("socket://localhost:50007");
InputStream is = sc.openInputStream();
OutputStream os = sc.openOutputStream();
os.write("Hello world!".getBytes());
is.read(buffer);
os.close();
is.close();
sc.close(); Edited by: andirady on Dec 4, 2012 11:59 PM

IDES for writing Java card applets and converting the applets as CAP FILE.

I have developed a JAVA CARD APPLET , FindMFValueJCA.java . It gets compiles in net beans 6.0 But while converting the applet to CAP file i am getting some errors. Is there any other IDES which take care of converting the CAP files

What's the Java version you are using?
As the java card tool kit has version dependencies. If you are using java_card _kit 2.2.2 then 1.5 is fine.

How to create an instance (or instances) of the java card applet?

Here I have a backend, a host application (a terminal)
and a Java card that needs to be instanced to multiple cards to different users.
I wonder how you can make instances of Java card applets of different IDs or PINs.

933351 wrote:
Yes, I would like to emulate an environment first, Unfortunately I cannot help with this (never really used this tool).
I'd like to know also how to install them later on real cards.You need something that can perform the secure channel and card content management functions of the GlobalPlatform card specification. A good starting point is GPShell. It provides a simple scripting interface to be able to:
1) Authenticate with a card with developer keys
2) Load you cap file(s)
3) Instantiate any instances you require (you can have multiple instances from a single applet)
4) Send arbitrary APDU's to the card for testing.
GPShell has a README text file that is a good reference and there are sample scripts for a number of card types.

Urgent ! writing a java card applet -APDU problem

hi
i'm fairly new to the java programming language. i'm trying to write an RSA java card applet to run on a java card simulator.
I am not sure at all what code i need to write for the CLA byte in the command APDU and what code i need to write for the INS byte in the command APDU, and where exactly to put it in my program.
if anybody knows please could you help me out.
So far i have written the code below.
thanx

Command APDU is not written in your source code, rather it is sent from PC or programmed Card Acceptance Device/ Card Reader/ Terminal.
The code installed in the Java Card should be able to handle the Command APDU received and process it accordingly, and finally your code should be able to send out response APDU.
You may think your code as a decoder, to retrieve each byte (CLA, INS, P1, P2, DATA, LC) using the Java Card API, you should be able to do it.
Also, I notice in your code that you want to work out with strings, but Java Card does not support strings, chars, long, float, double ...
to send out reponse APDU, there are certain steps that you can use, not just simply print like ordinary J2SE may use.
hope this will help u

I cannot load my java card applet Response APDU: 69 85

I know there have been many threads on this subject, I am a newbie to Java card development.
Please someone help me.
I am using the gpj for downloading the applet.
The following is the output from the command "java -jar gpj.jar -load JCHelloWorld.cap -install"
Thanks in advance

Problem Installing the loaded applet in Samsung java card (S3CC9P9).

Hi all,
Am trying to install the applets already loaded into the Samsung java card(S3CC9P9), because am unable to select the applet which are loaded into the card. I got to know that the applets are only loaded, they are not installed in the card, without installing the applet ,we cannot select the applet. Am using gpj(version 20120310 ) to install the applets into the card.
When i execute : java -jar gpj.jar -list
i get the list of applets in the card as :
AID: A0 00 00 00 03 00 00 00 |........| ISD LC: 1 PR: 0x1A
AID: A0 00 00 00 03 10 |......| Exe LC: 1 PR: 0x00

AID: D4 10 65 09 90 00 20 00 |..e... .| Exe LC: 1 PR: 0x00
Here am able to select only the first applet i.e., A0 00 00 00 03 00 00 00
SO, when i try to install the other applets, for example A0 00 00 00 03 10, its fails.
When i execute : java -jar gpj.jar -install -applet A00000000310

Can anyone please tell me where am wrong and how to make the applets selectable.
Thanks in advance

hy
1. do you have a reader with a serial (com1) connection?
if so, the reader has to be connected before starting windows. so windows recognizes it.
2. have a look to the control panel. is there a tool - installed during driver installation - to test and configure the reader?
if so try it.
if all that works, the jcop tools communicate with the reader over the installed driver.

Inter-applet object shareing concepts in java card

hi there.
what is a way of implimenting inter-applet object shareing in java card?
is there any shared area of JCRE for sharing some values among some applets in same java card?
thanks.

hi, as i know, there are three approaches:
1: shareable interface;
2: entry point;
3: global array;
and if the applet has JCRE privilege, then it is overwhelming.
for details , please refer to the JCRE Specification.
