New to Java card

I want to develop an aplication with java cads, for this porpouse I've chosen the JCOP41, but I have some questions:
1. Where I can find the JCOP41 appart from http://www.usasmartcard.com (I preffer Europe)
2. While I'm waiting to JCOP tools can I work with eclipse JCDE plug in. I mean If I can write in the card and simulate with this insted of JCOP tools
3. If I want to use a token for digital signature wich one do you recomend me?
Thanks and regards

Thank you for answer my friend,but I have a studies project about javaCard 3 connected edition,so I hope you could give me a practical example of how I can deploy them in smart cards,so what mean I use to deploy it,should I get smartcard writer or reader,or what should I get and I do?Hi,
You will not have much luck finding commercially available Java Card 3 cards yet. If you want to be able to deploy to a real card rather than a simulator in the near future you will want to look at Java Card 2.2.1 or 2.2.2. To deploy to a card you will need a PC/SC card reader and software that can authenticate to the card (what this software needs to do is also outlined in the GlobalPlatform card specification). This will give you the ability to write to the card as well. Search the forum for recent posts on card reader vendors.

New on java Card

HI all !
I'm new on java card technology and would like to compil my first cardlet :)
I'm getting problem while charging my cardlet into my chip, Eclipse does not generate the cap file.
I'm using Eclipse 3.3.1 and JCop Tools 3.2.7.
I created a Java card projet and a Java card Applet file and here is my code :
package pck_calculator;
import javacard.framework.APDU;
import javacard.framework.Applet;
import javacard.framework.ISO7816;
import javacard.framework.ISOException;
import javacard.framework.Util;
public class Calculator extends Applet
     private static final byte[] CALC = { //
     (byte) 0x63, // c
     (byte) 0x61, // a
     (byte) 0x6c, // l
     (byte) 0x63, // c
     (byte) 0x75, // u
     (byte) 0x6c, // l
     (byte) 0x61, // a
     (byte) 0x74, // t
     (byte) 0x72, // r
     (byte) 0x69, // i
     (byte) 0x63, // c
     (byte) 0x65 // e
     }; // Tableau de bytes (code ASCII) qui va être renvoyé si on envoit l'INS 0x00
     //methode d'installation de l'applet dans la carte
     public static void install(byte[] bArray, short bOffset, byte bLength)
          // Enregistrement de l'applet (méthode register()) auprès du JCRE
          // Lors de la création de l'applet (new)
          new Calculator().register(bArray, (short) (bOffset + 1), bArray[bOffset]);
     public void process(APDU apdu)
          //pour verifier que cette applet n'est pas entrain d'être sélectionné
          if (selectingApplet())
               return;
          //réception de la commande APDU
          byte[] buf = apdu.getBuffer();
          switch (buf[ISO7816.OFFSET_INS])
               case (byte) 0x00 :

                    return;
                    // Ici, on copie le tableau (défini en haut) dans le buffer et on l'envoi sur la sortie

                    // Ici, on additionne P1 et P2
                    break;
               case (byte) 0x02 :
                    //Soustraction de P1 et P2
                    buf[0] = (byte) (buf[ISO7816.OFFSET_P1] - buf[ISO7816.OFFSET_P2]);
                    break;
               case (byte) 0x03 :
                    //Multiplication
                    buf[0] = (byte) (buf[ISO7816.OFFSET_P1] * buf[ISO7816.OFFSET_P2]);
                    break;
               case (byte) 0x04 :
                    //Division
                    if (buf[ISO7816.OFFSET_P2] == 0)
                         //Test de la division par 0
                         ISOException.throwIt(ISO7816.SW_INCORRECT_P1P2);
                         //Envoie de l'exception "mauvais paramètres"
                    buf[0] = (byte) (buf[ISO7816.OFFSET_P1] / buf[ISO7816.OFFSET_P2]);
                    break;
               case (byte) 0x05 :
                    //Somme du champ de données de la commande APDU
                    short n = (short) (ISO7816.OFFSET_CDATA + apdu.setIncomingAndReceive());
                    byte sum = 0;
                    while (n-- > ISO7816.OFFSET_CDATA)
                         sum += buf[n];
                    buf[0] = sum;
                    break;
               default :
                    //Envoie de l'exception "mauvais champ INS"
                    ISOException.throwIt(ISO7816.SW_INS_NOT_SUPPORTED);
          //Pour tous les cas la réponse APDU a des données de 1 octet
          //Sauf pour le cas INS = 00
          apdu.setOutgoingAndSend((short) 0, (short) 1);
}It's a simple calculator :)
To compile, I use right click on the projet => debug as... => Open debug dialog
and I set the correct AID of the package and class in the "Package upload".
Then I start debug and here is the problem :
The .cap is never created (cm> upload -d -b 250 path/file.cap)
The comunication with the card is ok because it answers some request like /card-info.
Do you have any idea about a step I forget or anything else ??
Thanks a lot :)

At first, I tried java compiler 5.0 as the over topic and could get a cap file but I think it is not usable.
I changed to your configuration as compiler 1.3 and class compatibility 1.2 and problem is still the same.

Can any one suggest me how to tactile this new technology JAVA CARD

HI
I AM C.NAVEEN . I KNOW BASICS OF JAVA. AND STUDIED DOCUMENTATION OF JAVA CARD , AND UNDERSTAND THE CONCEPTS REGARDING THAT. BUT HOW TO CHOOSE A CARD AND A CARD READER .
AS I AM NEW TO THIS TECHNOLOGY . HOW CAN I MOULD MY SELF TO BE A PROGRAMMER FOR JAVA CARDS .....................
Thanks
Naveen.C

Because the Windows 8 is a client operating system. To make BI4.1 Server work on windows, you'll have to make sure you install it on versions supported as per the PAM below:
SAP BusinessObjects BI 4.1 Supported Platforms (PAM)
Please refer page #3 for server operating system, where you will be installing the server software and for all the client tools - refer page #4.
Make sure you install the server and the client tools as per the supported OS types and versions respectively.

Request information new on java card

hi,
i 'd like to developp a smart card , after searchin articles and read them i understand that :
to developp a java card i should have a smart card ( micro processor) a reader then the computer(with the developpement kits ....).....then u can start codin the applet ...
let's say that the applet is installed on the java card , and want to give it to a customer ,
questions :
where he should insert this card (into a terminal i guess and how this terminal will send the APDU command ?? )
are the terminals a computers or a special card reader ?? where can i buy one ??
i heared that it's possible to isntall programms the terminal ??
thxs for replying
regards yacine;

where he should insert this card (into a terminal i guess and how this terminal will send the APDU command ?? )
If you are doing a desktop solution, the reader will be installed on the desktop. To send APDU commands, use middleware like PCSC.
are the terminals a computers or a special card reader ?? where can i buy one ?? Just google smart card readers for vendors. Just focus on ISO7816 compliant readers. Commonly used ones are from SCM Micro.
i heared that it's possible to isntall programms the terminal ?? Some readers like SCM Micro are field upgradeable.

I am new to java card . I am running the Sample Example given and some.....

I am using the ACR 38 Smart card System
I am running the applet file of ACOS 3

Hey Carolyn1951,
Thanks for the question. I understand you have a few apps that only display "Waiting". The following is a past discussion that dealt with a similar issue, the answer may help you as well:
App updates won't download on my...: Apple Support Communities
https://discussions.apple.com/thread/4111336
Try tapping the App, so that it changes to Paused instead of Waiting, then tap it again to resume the install.
Make sure you don't have any paused downloads in other apps either, like the App Store or iTunes Store.
If that doesn't do it, try resetting or restoring the iPhone.

Can anyone tell me what is this output? And Am i deplyoing in the right way?

Hi,
You might want to check the JCDK user guide (cJDK_Users_Guide_bin_do.pdf) for details of using an emulated card environment. It outlines how to use the simulators provided with the JCDK. This should tell you how the deploy process works and will give you some insight into what this script is doing.
Cheers,

Java Card program execution on Eclipse

Hi Dears,
I am new to Java Card. I did setup to run Java Card programs on eclipse using http://eclipse-jcde.sourceforge.net/.
This is my simple program below
import javacard.security.RandomData;
public class Main {
     public void main() {
          RandomData rd = RandomData.getInstance(RandomData.ALG_SECURE_RANDOM);
          short outLen = 10;
          byte buffer[] = new byte[outLen];
          short outOffset = 0;
          rd.generateData(buffer, outOffset, outLen);
Compilation is successful but when I run the program I get the following error.
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/String
This is very annoying. I think my run time environment is not ok for running java card programs. I am able to run Java programs but not java card programs. Any one can help please?
Thanks,
Regards,
Naveed

please post code with {code} tags

Starting java card

I am new to java card can anyone tell how to begin
from installing ide or toolkit to writing application please provide links for downloading ide or api's
thanks

As for the IDE, you can use Ecplise with the Java Card Plugin:
http://www.eclipse.org/downloads/
http://eclipse-jcde.sourceforge.net/
Of course, you will also need the Java Card Development Kit:
http://java.sun.com/javacard/devkit/
Also, check out this tutorial on Java Card applets:
http://www.javaworld.com/javaworld/jw-07-1999/jw-07-javacard.html

Java Card for healthcare applications

I am quite new to Java Card and I am currently developing a healthcare applications using Java Card. What is best:
Storing the patients medical history on the card itself
OR
storing it on a database and use the Java Card as a access token?
Thanks.

Besides the fact that the storage capacity of todays JavaCards is very limited. This question is IMHO more a plitical question (and a question of privacy) than a technical question.

Where to get Hardware (Java Card & Readers)

Hello
I am new to Java Card Technology. well i have Downloaded the Java Card 2.1.2 Devlp Kit. Thats fine , But from where should i get Hardware like Java Cards & Readers. I am working in Research Institute.
& wat are the steps to start with it.
Please guide me soon.

Sun doesn't provide cards or readers. Their kit is serves two purposes. One is for the integrators that are shipping cards and readers. The other purpose is for developers to learn how to develop applet without a card. For example, no one is shipping 2.1.2 cards yet,( I don't think) but you can still develop a 2.1.2 applet with Sun's kit. You just won't have a card to deploy you applet to.
If you develop a 2.1.1 applet you can use Gemplus cards and deploy your applet there.
If you want to start developing go to www.javasoft.com/products/javacard. Download a sdk, and read tutorials.

Simulator for java card

hi
i am new to java card technology...i am writing the applets in netbeans using java card plugin....the problem is i m not able to simulate the applet..it is showing build successfully, but wen i run the app it is showing nothing.....so can anyone suggest me a suitable simulator for the same....

Hi,
I assume you are after details on how to use the simulators? There are examples and documentation with the JC specifications and developer kit. Both of these are available from the Sun website [http://java.sun.com/javacard/].
If you are after details on how to develop your own, the JC specifications outline the requirements for the JCRE and JCVM that you can use to implement a simulator.
Cheers,
Shane

Java Card Virgin

Hi guys,
I am new to Java card and there's a project I need to develop with it. I need advise on the card reader to use, preferably with fingerprint scanner and also the particular Java Card to use.

The int keyword and its 32-bit integer data type are optionally supported.
what is wrong with using a byte array ?
you can convert long to byte array and vice versa with your
own code.

Writing into file in java card

hi
i am new to java card. What i need to do is to write a value in a particular file and read it everytime the mobile is switched on. Can anyone please guide me how do i create this file and read and write into it

Not really a SQL Developer question. You would be better over in the SQL and PL/SQL forum.
You don't say what DBMS version you are using but if it is 10g or later, you don't need to restart the database to enable directories to write to.
The utl_file_dir initialisation setting should no longer be used. Use CREATE DIRECTORY instead.
