Java card technology question

Hi all
Im new to the java card technology. I've downloaded and installed the java card kit and tested the demos on the virtual environment. I have the towitoko card reader, downloaded the cttwkw32.dll, but i dont know how to communicate with it.
Can pls anyone tell me what steps should i follow in order to be able to communicate with the reader? is there any IDE for building such applications (except for the eclipse and the jcop toolbox)?
Thanks in advance.

javacard.framework is defined in a jar file, supplied with Java Card Development kit from here: http://java.sun.com/products/javacard/downloads/index.html
As for
import sim.toolkit.*;
import sim.access.*;
This question is already discussed here:

Java Card Technology

Hi,
Iam new to Java Card Technology, Can any one explain me how to compile a java card program using eclipse.
and from where do we need to pass apdu commands, how to check the output(data which is written into smart card), etc...
Thanks,

For Eclipse there is are the famous JCOP Tools. To get these you need to contact your local NXP sales representative. The tools itself are free of charge. There is also an open source Eclipse Java Card tool. Forgot the name.

Java Card Technology for Smart Cards: Zhiqun Chen

Hi,
I have this book but its using Java card 2.0.
do you know if the author "Zhiqun Chen" have new one for 3.0 connected.?
http://java.sun.com/developer/Books/consumerproducts/javacard/
Edited by: Hassan on Apr 20, 2012 3:45 AM

That is the latest copy. It is still a good reference for getting started and contains some more advanced topics that are relevant to newer JC versions. I am not sure if a book on connected edition is relevant considering there is no real application that I am aware of. You may be able to get cards that support JC 3 classic though.
The book is available on Amazon: http://www.amazon.com/Java-Card-Technology-Smart-Cards/dp/0201703297
It is well worth the $33.

Some questions about Java card.

Hello, everyone. I am a rookie in Java card. My major focuses in IC design so I have some questions to ask.
1) As I understand, Java card technology is just a platform.So the regular processor can be used for Java card? What we need to do is just software?
2) How to get the Java card license? All the Java card tech file are released to customers. And how much is the license fee?
3) How much one Java card cost?
Thanx.

Hi,
1) Yes that's right the only think that you have to bother on a JavaCard is the software part. You will have to develop an applet that you will then download and instanciate in your JavaCard.
2) For any technical specifications and JavaCard SDK, have a look to this URL:
http://java.sun.com/products/javacard/index.jsp
Regarding the licensing, yo may find some information at this URL:
http://www.internetnews.com/dev-news/article.php/70381
3) The cost of a JavaCard depends on the volume, the card manufacturer. I think, the price of a JavaCard for low volume is from 5 to 10 USD. But you better do some enquiry with a card manufacturer.

Java card confusing Issues!!!!!!! java card architecture, advantage!!!!!

QUESTION -1
As I know about architecture of any application is -
                //normal java software                          java card                                  java card
                  // 1                                               2                                      3
1-            application program                        host application                           host application
2-                     JVM                                   Applets                                       Applets
3-              operating system                JCRE(which contain all classes, JVM ....)                 JCRE(act as a O.S too)
4                    hardware                              Operating system                                 H/W
5                                                                        hardwareWhat do u think- case 2 is right? or 3 is!!!!!!!!!!!
I think - case 3 is right!!!!
As i study from several sources , JCRE is complete package - it behaves as a operation system and use the functionality of component it contain. I also think if i will purchase a java card from any vendor , it would have JCRE inside it (means everthing inside it,), i only need to develop the applet according to my requirement and install it by on card installer program
QUESTION 2- what is the advantage of java card.?
// I think.
as i read out , i got the line that it is platform independent and support multiple application. applicaton point of
view , I am agree but how it is platfrom independent. if we use java card for smart card development, then
i will purchase Java card from differnt vendor , all will provide me card with supported jcre inside it, so why
this is advantage here?
// in case of window based application , it really make sense because if i will make any window application with java
// i can run it in windows , linux , unix and most of os flavours, here i can see the beauty of java language.
Clear me this and add some other java card advantages, which make java card goodquestion 3-
Now I am capaple to make simple applets, so I want to check the entire java card process atleast once before
going in deep of something, I am thinking to implement prepaid card concept , i made it applet for it ,it will
contain a page with 2 text box ( 1- for recharge 2- for money deduction ) and two button , with button click i
want to select the applet and want to pass the apdu.
( a) how i can make host window application ? (i think awt will work for me? , *
i never make any java window application yet) *
( b) still i dont have any java card , i want to make it by using simulator, is it possible?
(c) in this scenario what framework i need to study Ex. Import javacard.framework.* for making
applet or from where i need to start.Regards:

5                                                                        hardwareWhat do u think- case 2 is right? or 3 is!!!!!!!!!!! If you are using Java Card then JCRE+JVM = OS and if you put this on ein package 3 then 3 is correct according to me.
As i study from several sources , JCRE is complete package - it behaves as a operation system and use the functionality of component it contain. I also think if i will purchase a java card from any vendor , it would have JCRE inside it (means everthing inside it,), i only need to develop the applet according to my requirement and install it by on card installer program Actually it depends. There can be following models in this regards:
1. Buy a empty smart card, Install your own OS and then write your applets for it.
2. As you said, Buy a card with preloaded OS and then write applets for it.
QUESTION 2- what is the advantage of java card.?
* Interoperable: Applets developed with Java Card technology will run on any Java Card technology-enabled smart card, independently of the card vendor and underlying hardware.
* Secure: Java Card technology relies on the inherent security of the Java programming language to provide a secure execution environment. Designed through an open process, the platform's proven industry deployments and security evaluations ensure that card issuers benefit from the most capable and secure technology available today.
* Multi-Application-Capable: Java Card technology enables multiple applications to co-exist securely on a single smart card.
* Dynamic: New applications can be installed securely after a card has been issued, enabling card issuers to respond to their customer's changing needs dynamically.
* Compatible with Existing Standards: The Java Card API is compatible with international standards for smart cards such as ISO7816, or EMV. Major industry-specific standards such as Global Platform and ETSI refer to it.
* Developers creating Java Card applications enjoy all the advantages of working in the Java programming language:
Object-oriented programming yields greater code modularity and reusability, leading to higher programmer productivity.
Protection features characteristic of the Java programming language apply to Java Card applets, enforcing strong typing and protection attributes.
Powerful off-the-shelf development tools are readily available.

And also, in case of SIM card if you are using java card then RAM is possible and native cards don't have this ability.
question 3
Now I am capaple to make simple applets, so I want to check the entire java card process atleast once before
going in deep of something, I am thinking to implement prepaid card concept , i made it applet for it ,it will
contain a page with 2 text box ( 1- for recharge 2- for money deduction ) and two button , with button click i
want to select the applet and want to pass the apdu.
( a) how i can make host window application ? (i think awt will work for me? , *You can use swing for this to make interface and use smartcardIO http://docs.oracle.com/javase/6/docs/jre/api/security/smartcardio/spec/javax/smartcardio/package-summary.html for sending APDUs.
i never make any java window application yet) * It is easy you can look here and start: http://www.roseindia.net/java/example/java/swing/
( b) still i dont have any java card , i want to make it by using simulator, is it possible?Actually, smartcardIO will only interact with actuall card and for simulator you will have to use console for sending APDUs.
(c) in this scenario what framework i need to study Ex. Import javacard.framework.* for making
applet or from where i need to start.For your current case it is enough and for host app you should study smartcardio as i mentioned above.
Hope it helps.

Java card applet debugging in Netbeans 6.8

Hi,
| am writing a Java Card applet and a client MIDlet. I would like to debug my applet: I want to see the interaction process with MIDlet. However, for some reason I cannot start debugging in Netbeans 6.8. Could someone help? Thanks in advance.
Regards,
Aleksandr

Hi sanyas,
sorry, i'm not answering your question..
I'm a newbie in Java Card technology..
After i had read your post, it makes me curious about Java Card Client..
I want to know, what kind of Java Card Client that we could create?..
Can we create a Java Card client application from Java SE (GUI/Swing base application), or it's limited for MIDlet only?
Thanks in advance..

Post Issuance of Java card applets

Dear All,
Can any one let me know where i could find some documentation on Post issuance of smart card applications in detail.
I'm working with gemXpresso 211 PK IS, which supports Open Platform 2.0.1 version.
Appreciating your quick reply
Thanks and Regards

You mean to say gemXpresso 211 PK, is OP 2.1 compliant(not 2.0.1),
but in any case, OP2.1 implements CALC(Card and Application Life Cycle)
who has some responsibility of post issuance management. Although there
are not many references of post-issuance in OP2.1 specification(11 to
be exact) and not what information you are looking for. I would say the
vendor(GemPlus in this case) should be able to answer any specific
questions you may have for the process of Applet post-issuance.
You probably already have gone through the generic post issuance
Applet description with respect to Java Card in Zhiqun Chen's
"Java Card Technology for Smart Cards"(P.46).
I afraid this is not the answer to your question perhaps, but I
suspect if there really is any specific documentation on Applet
post issuance and likely chances are it would be a vendor dependent
process.

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 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

Java Card Please Help!

Please I am doing my final year project on secure mobile application using Java Card Technology.
I need to write and an application that can send SMS on a SIM card to another SIM card with the same application. The application will have a server side which manage the storage of messages and at the same time communicate information to the client on the SIM remotely. I am suppose to use wi-fi (TCP/IP) for transmission.
Can anybody please give me ideas and possible working codes and simulators.
I mean step by step procedure of how to start.
THANK YOU.

Hi,
I found the following resources helpful when starting out in JavaCard.
JavaCard documentation:
Java Card Technology for Smart Cards: Architecture and Programmer's Guide (Book)
http://java.sun.com/docs/books/javacard/index.html
JavaCard specifications:
http://java.sun.com/products/javacard/specs.html
Global Platform specifications:
http://www.globalplatform.org/specificationview.asp?id=card
Communication between SmartCards and terminals is based on ISO 7816 part 3 and 4 so if you�re completely new to the SmartCard environment it may be helpful getting an overview regarding these specifications. Unfortunately these specifications are not free, they�re available from.
http://www.iso.org/iso/en/ISOOnline.frontpage
Software:
The basis for all development is the JavaCard and Java Development kits.
Java Development Kit
http://java.sun.com/j2se/1.4.2/download.html
JavaCard Development Kit
http://java.sun.com/products/javacard/dev_kit.html
Full installation instructions can be found in JCDevKit_User_Guide.pdf which is contained in the JavaCard Development Kit distribution.
Several companies provide IDE�s that will aid you in developing and deploying applets to JavaCard.
For example:
Aspects Developer
http://www.aspectssoftware.com/devtools/index.html
There are others out there as well. You may need to also buy physical sample cards; however, the IDE�s usually have simulators built in.
Hardware:
To interact with physical cards you�ll require a PCSC compatible card reader.
Omnikey

Hope this helps.

Java Card Applet Development

1. Good.
2. I suggest you start testing using the simulator, however if you want to test directly on the card at once, select your card reader using the /term command and use the commands as described in help to start sending APDUs to the card.
3. This is not a part of the JCOP tools for eclipse (which is developed by IBM and maintained by NXP), but part of the JavaCard development toolkit developed and maintained by Sun. See http://java.sun.com/products/javacard/dev_kit.html.
4. Read the above. None of this is part of JCOP tools for eclipse.
5. As far as I know, there is no independent newbie guide for JCOP tools, but I would check out the help function included in the tools themselves if I were you.
Good luck!

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.

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.
