Acquiring a Java Card

Hello,
My company wished to update its authentification system, and replace the actual magnetic card by a Java Card. I have a few questions to ask ( some of them are very newbie, sorry :) :
1. Does some models exists with a magnetic part ?
2. I saw severals models, CyberFlex (SLB), Gemplus ... there are a lot of company which create Java Cards ... are there big differences between these cards ?
3. My company acquired a long time ago a smart card reader : GemPlus GCR400. Does it Handle Java Cards, or must we acquire a new one ? Do I need a specific card reader for one type of Java Card, or maybe every Java Card works in any smart card reader ?
4. Could I start to program some piece of software and test it on an emulator ? Does emulators exists ? If yes, could you give me links to get them ?
Thanks in advance.

1. Yes, look at the Visa card, and the American Express card.
2. Nothing, other than crypto implementations. That's the purpose of the Java Card API.
3. Yes, any ISO reader will work.
4. Yes, an emulator comes with Sun's kit. Most vendors except SLB, provide simulators with their kits.

How to run Java Card Program in a Simulator

I m Narendra Reddy studying in India and have taken Java Card for my B.E. final year project.
i also acquire knowledge of Whole Java Card Development Life Cycle but i found much more difficulties to implement those ideas into java card.
so, Will you please do me a favour and give me a complete solution if possible with an example.
i also want each step with the commands, from the creation of Class file to the running of prog. in simulator.
it will be very useful for me to head towards my project.
Thank you,

Just for the record,
Since we are looking at different possibilities, there are couple of ways to achieve simulation/testing environment for current Java Card,
1. "The Java Card Workstation Development Environment(JCWDE) tool allows the simulated running of Java Card applet as if it were masked in ROM. It immulates Card environment." Although, as Joe mentioned, it does not support;
- package installation
- applet instance creation
- persistent card state
- firewall
- transactions
- transient array clearing
- remote method invocation
- applet/package deletion
Thus you can use 'jcwde' tool in combination of apdutool to test some
of the Applet behavior(& JCRE) but not all. You have realized this when you tried 'sample' applets.
2. JCDK2.2 also provide c-reference implementation of the Java Card. This(cref) is more robust way to test Applet. Although the catch with this is that Sun does not have SCSL(Community Source Licensing) program for Java Card(alas!) and this means you can not mask your applet into this reference implementation unless you get hold of source code somehow(source licensing is one(costly) way)
3. Buy reader/card and figure out how to install applet for
testing purpose.
4. Buy kit from JC vendor containing reader/software/cards and use it
(costly and hard to find JC2.2 implementation)
1 and 2 are easier but not a real life solution(how many cards with intel/sparc processor anyway?). 3 and 4 are ideal but other way challenging. Yes, probably solution-1 is the right for your purpose.

Java Card compatibility with readers... (please help me!!)

Hi,
I would like to know how to determine the compatibility of a existing reader with the JavaCard technology.
I have studied the standar ISO 7816 and I'm not sure if a reader must be compliant with absolutely all
parts of the standar (Part 1,2,3,4,5,6) to be capable of read, write Java Cards and select the applet to
execute.
Especifically I need to know if the readers GEMPC410 and CASTLES EZ200 are able to read, write
and execute multiple java applications.
The specifications that a read, said that GEMPC410 can read and write ISO7816 1/2/3/4 and
CASTLES EZ200 can read and write ISO7816 1/2/3 but i have the following doubt:
These readers should be compatible with the part 4 and/or 5 of the ISO standar to
interchange commands with the reader (Part 4) and identifie the applications to execute (Part 5)?.
Where I can find more information about this issues?
Thank you very much for your soon answer.

Well,
There are two type of readers you can use with JavaCards:
Contact readers
As specified in ISO7816, for the contact readers working with T=0 and T=1 protocols. On win machines they are normally supported with the PC/SC interface, most of the readers are able to talk to that interface. In other words - if you can use any card on ur comp and if it is win platform JC will work fine.
Contactless readers
As specified in ISO14443, this babies are talking T=CL protocol. For now I know only JCOP30 products that are operating also in contactless mode. For this you will have to acquire some contactless reader and they are commong with drivers for standalone apps or for the PC/SC IF.
But chance that you will use the second option in next 3 years is rather small.

The only Official Java Card OS

IBM is in talks with Sun about an acquisition, if it happen then JCOP will be Official Java Card OS. good for NXP.

http://www.sun.com/third-party/global/oracle/
Sun Microsystems (NASDAQ: JAVA) and Oracle Corporation (NASDAQ: ORCL) announced today they have entered into a definitive agreement under which Oracle will acquire Sun common stock for $9.50 per share in cash. The transaction is valued at approximately $7.4 billion, or $5.6 billion net of Sun's cash and debt.
OK, no more Sun Java card, Now is Oracle Java Card!

Need suggestion regarding simulation of Java Card using a floppy

Hi All,
I am working on a project wherein I have to simulate a Java Card application using a floppy. I am writing my own Card Terminal and CardTerminalFactory. Thats what I have started working on. Will that serve the purpose or do I have to think about some other approach like just overriding the cardInserted method of CTListener class? I want to achieve communication between the host application and the floppy(which is my java card) Please advise.
I would like to thank DurangoVa and Nilesh for helping me out sorting out the error in running the converter.
Thanks in advance

Are you referring to a Floppy diskette drive ?

Step by step installation for java card kit 2.2.2

can anyone help me with a complete step by step installation information for java card kit 2.2.2, i already tried to follow the instruction given in the software i download n still stuck in setting the java path. any recommendation
thanks for the help

The javacard API is for developing applets on card. Java 6 is for developing clients off-card.
yes u can use any java IDEs like netbeans or jcreator. But you will have to select the libraries within the downloaded java card kit folder for ur IDE in order to compile successfully.
try reading up the documentation and run the samples in the java card kit. thats a good place to start.

J2me and java card, need help to communicate

we are trying to put together a reader to read smartcards using j2me and we figure that it would be easiest if we could develop it to work with java cards rather than standard smart cards, the problem is we get garbage when we communicate to it, the chip sends us crap, any suggestions what might be wrong, any calls we might be missing, has anyone worked with j2me and java cards or smart cards, any help would be appreciated.
einar

.... reader app and the ME behind it .... smells like mobile ....
First of all - if you want to have one mobile application running on this just make sure that whatever is written in ME can use drivers from the reader chip ....
Workin on the PC is something completely different. There was one good example how to develop one host application in Java provided with the JCOP tools long ago ... I don't know if this is now in the new Eclipse tools.
But - there was a small API provided that can give you good hints what to do - and - once you have it on the reader side - you can easily integrate ME methods with this ...

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,

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

How to create a java card library (jar file to be used in other programs)

Hi all,
I am working on JCOP and writing quite a bit of applets for the java card . Now i have lots of code that could be reusable for example sending SMS, encryption routine, etc.. So this part of the code i want to put into a utility class and create a package out of it. This utility package i must be able to import into my programs what i write.
I tried the normal way of creating the jar by renaming the CAP file of the utility class, also tried including the /javacard/* files also into the jar file as indicated by sfarmer(active forum member here). But none seems to work. I tried contacting NXP folks and they indicated that it may be possible only by way of Sharable Objects.
But some how i am not convinced why i should use Sharable object for this. So if any one can throw some light into this regard it will be immensely helpful to me and my project.

Hi,
Well the variable defined are as below
public static byte[] msgdata = new byte[255];
private static final byte[] HEADER_TEMPLATE = {
          (byte) 0x81, (byte) 0x03, (byte) 0x01, (byte) 0x21, (byte) 0x00, // Command details tag
               (byte) 0x82, (byte) 0x02, (byte) 0x81, (byte) 0x02, // Device Identities tag
               (byte) 0x8D, // Text String tag
               (byte) 0x00, // length
               (byte) 0x04, // Text String tag
the msgdata is declared public so that i can access this as a Class member in my other program doing Utilities.msgdata. But the problem is now that if i dont declare it as final then the compiler gives me the below error
"library has initialized array for non-final, non-static field Utilities, msgdata, [B, attr jc-field: tok 0, public static"
If i make it final then i cannot change it... So now i am stuck..
Any help will be highly appreciated...

How to find out memory of a java card

is there anyone could tell me that how can we check the size of the memory of a card? thank you in advance:D

If the card is a Java Card 2.2.1, create an applet that returns
JCSystem.getAvailableMemory(), install and queryit.
Some other ideas for getting the free memory on card were presented in the thread "Java Forums - Free memory on card"

The version number of export file in Java Card 2.2 is not correct

Hi all,
I used jdk1.3.1 and java card 2.2's exp2text tool to see the content of an export file. The value of minor_version is 1. But the JCVM 2.2 spec. says it should be 2. So which one is correct?

Read my post again....indicate binary compatibility or incompatibility between successive implementations of a package.
I can gerenate CAP files generated with JC 2.2., and load onto my JC 2.1.1 cards. AS LONG as I'm not using JC 2.2 implementation.
Run the exp2Text on javacard.framework.service and notice that it should read minor = 2. That's because to use that export, JC 2.2 is minimal required implementation.
