Java Card Jobs in India

Hi All Members,
Since we people are working in Java card technology, But I am more focused about the career in Java card Technology. In INDIA specially we do not have scope to work on Java Card technology, I have been searching for good Job from 2 years but I could not able to find out. Could anybody from INDIA give me references for getting job into Java Card , It would be helpful for me.
Kindly reply.

Hi lexdabear,
Thank you for your reply. Natives OS mostly required development in C, But what about Java Card technology where we can get the opportunities to work on Java card I mean some other countries. Do you have any idea then please share.....

Require java card vendor(s) in india

hi friends,
can any body send me java card vendor(s) list plz.

You can also use OpenCard Framework (OCF) to communicate with the CREF emulator from a host application. You should be able to search the forum for related posts for details.
It is a very good idea to test against an emulator when developing as it is faster and may allow you to debug your code as well. Just remember that the CREF and JCWDE emulators have limitations. These are described in the documentation that ships with the JCDK.

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 ISO 7816 file system

Hello
Java Card technology dose`t provide core APIs for ISO file system.Is there any mechanism for creating DF and EF on java cards.If there is,please guide me.Is there any sample code for this subject at sun.com?I want to creat DF and some EF on a java card and then manage them.How I can do it?Please guide me.

JavaCard doesn't contain a file system. It's been repeated in this forum over and over. How many times does this have to be answered ? Have you searched to forum prior to asking ?
For JavaCard there isn't a need for a filesystem because of the power of having a language on the card. Also byte arrays with a TagLengthVariable (TLV) do the job just fine.

X.509 Certificates on Java Card

Hi,
I'm a newbie on this and am looking for any help I can get.
I am wanting to store or generate an X.509 certificate securely on a Java Card for an application which either requsests the certificate or gets details from the certificate to the application.
I am currently using keytool to generate certs to get an idea of things. I have no hardware (card/reader) and am currently reliant on SUN's jcwde .
I have looked for proprietary javacard api's on X.509 and found nothing on this. So I guess I will have to write my own code to do the job using the standards involved.
What I guess I'm looking for is anyone out there to tell me wether it is feasable to do what I wish and any pointers on how to go about it.
Thanks in advance ...

You can't generate a cert on the card because of the technology of certs. Of course, you can store them on the card. It's up to your design how to store it. For example, you might want to store it in PKCS#15 format, or just raw data format, or actually importing the private key using the JC API. Keep in mind you can generate keys on card using the JC API.
What you are describing is very common with PKI solutions that need a secure token. The smart card is that token.

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 ...

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.

How to Schedule Java statistics job

Hi All,
We have a installed a NW07 Portal system on one of the unix boxes.Now we would like to run the oracle statistics on the same. Since there is no ABAP stack, we can't schedule the same thru db13. Is there anyway we can run the same.
Can I configure the Java statistics jobs for this from the central solution manager using the DBACOCKPIT.
Can somebody tell how to do this??
Thanks for the help.
Regards
Ravi

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...

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...
