Load applet into JCOP 30

hey,
i have some troubles to load my applet into a JCOP 30, i use GPSell to load my applets, i've tried JCOP's scripts included in gphsell but i failed to load my applet, its probably due to the key of authentification. please, what can i do to ?

this is a copy i get from output gpshell using JCOP10 script

Hi all,
Sorry above i forgot to mention the java card am using. It is JCOP21 and in its datasheet its mentioned that it specification needed are javacard development kit 2.2.1, is that may be the reason for this error?
Thanks in advance

Is OCF related to loading applet into the sim

I've read some text about OCF(Open Card Framework) it is said that it is an interface to both smart card reader and applications on the sim. if we take "the application on the sim" same as "Installer Applet" then the ocf stands in the place which the problem of loading applet exists.
could you please explain:
Can I use OCF for witing a programm to load my applet into card?
Is There any other way to do the task??

If it is a GlobalPlatform card, there are some simple steps to validate if your card is locked/terminated
1. send GET DATA on some tag you know for sure is in the data store of the CardManager
2. If this works, try to authenticate (INIT-UPD, EXT-AUTH)
3. If this works, GET STATUS on ISD --> AID and life cycle of the CM
- If 1. does not work, then your default select application is not the ISD --> contact the issuer for the AID
- If 2. does not work, then your card is locked or terminated
- If 3. does not work, then the GP secure channel protocol on-card has a different implementation than your off-card tool/API (most likely with a Gemalto card)

Load Applet to Java card

hi,
I load A applet to java card. Then i load B applet.
But i want to load if key match then only load A or B applet.
How can i maintain load applet.
I am using Eclipse SDK JCOP31 tool.

thanks for reply.
I am using Eclipse SDK JCOP 31 tools for Java card applet development and loading same into java card.
when loading applet into java card some internal authentication process is handled by JCOP.
But i don't have clear idea about this authentication process.
So can any one explain which algorithm they used for authentication & how they will be setting the Key for the same.
If i want to change the algorithm and key in JCOP how i can proceed?
Regard,
Senthil

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

You can't debug an applet in ROM with JCOP Tools.

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
i get :

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.

Is it possible to load applets if ki imsi iccid are known?

is it possible to load applets if ki imsi iccid are known for a sim? if the sim is given by a mobile operator. how to connect to such a card using jcop/javacard.

bilal,
is it legal to post answer here ?
anyways i am posting here for knowledge only,hope nobody will do any mis use.
u have generate KI from ICCID & IMSI(ICCID & IMSI u can read from SIM file system)
for KI generation , u can find any s/w from internet search,which will generate KI from ICCID & IMSI using broute-force attack,
then replace KI of ur SIM with generated KI,
thats it,ur job is done :-)
now u can connect to CM as u have ADM 0 privileges for SIM.
cheers

Loading images into memory

I have an applet that I need to load images into memory. For instance, lets say I am in the first section of the applet. While that section is being showed, I want to load the background image of the second section into memory.
To load the initial image into momory, I am just using a Mediatracker. No problem there. But I don't want to load all 20 backgrounds into memory at the same time as they take a lot of time. My understanding is that if I create a new MediaTracker while the first chapter is running, it will potentially cause some chaos, as that will stop my thread from running while I have an image loading.
Somebody told me perhaps I could create a new thread and have that thread load the backgroudn into momory? Perhaps something like this?
public class TestClass extends JApplet {
     private TestClass thisClass;
     public void init() {
          thisClass = this;
          Runnable r = new Runnable() {
               public void run() {
                    MediaTracker tracker = new MediaTracker(thisClass);
                    Image nextImage = getImage( getDocumentBase(), getImagePath() +"img1.jpg");
                    tracker.addImage(nextImage,0);
                    try {
                         tracker.waitForID(0);
                    } catch (InterruptedException ie) {
                         System.out.println(ie.toString());
          Thread t = new Thread(r);
          t.setDaemon(false);
          t.start();
          while(t.isAlive()) {
               int i = 1;
          t.stop();
          t.destroy();
}No idea if I am on the right track or not? Another friend told me something about swing helpers but couldn't tell me much more?
Thanks in advance!

I use media tracker when I need information about how percent the image is loaded. you can use JLabel to load the images since it has own image observer in it.
hope you just want to deal with it. easiest way I can offer :)

Applet not found for installation.
�Cause: An attempt was made to create an applet instance, but the applet code was not installed on the card.
�Solution: Verify that the applet package has been downloaded to the card.
so, what step did i miss here??
thank you
PS: i also tried with JCWDE but the error was the same

I've noticed that my applet uses the java.lang package. For what i've read the CREF only has installed the Installer Applet and the javacard.framework package, so can that be the problem? i.e., do I have first to load the java.lang package into the simulator??
I really need help...i'm literally stuck on this....

Debug STK applet with JCOP 3.0

Hi all
i want to debug my STK applet with JCOP tools in eclipse plugin.but somehow i am not able to debug my SIM toolkit with JCOP.
first ques , is it possible?
right now i m debuging in manu project---->debug
then i m choosing java card application to debug,but its not working:(
how can i proceed step by step for debuging?
one more ques,
is it possible to load applet on java card only with JCOP tools?(means without any s/w like views professional or aspects developer.)
Regards
Divyesh.

Hi all.
I'm having the same problem. I know that a html file is created everytime the applet is invoked (clicking on debug or run) with a diferent name to be called as argument of appletviewer.
But I will join to the question... How can we use our testpage to do a test of a devel applet?
Because mine has to be used with javascript and it's very difficult to test it without a custom test page or appletviewer...
Thank you all

Loading Applet on a Smart Card

I am new to JavaCard development so forgive me if you find the question stupid.
I am trying to load an applet on a NXP based Sm@rtCafe Expert card. I have completed the following steps:
- Compiled the applet
- Converted the package into a cap file using the Converter tool.
- Generated the upload scrpit file using the scriptgen tool and appended the requisite powerup and powerdown commands.
Now when I try to upload the applet through the apdutool, I get an exception.
Here is the apdutool command I am using:
apdutool -t0 upload
Where upload is the name of my script file.
I am getting the following exception:
Opening connection to localhost on port 9025.
java.net.ConnectException: Connection refused: connect
So my card reader is probably not on the default port is what I gather. How do I find out what port is my reader at if that is the problem.
For additional information I am using JavaCard 2.2.2 development kit along with JDK1.5. My card reader is a USB based SCR3310 reader manufacture by SCM Microsystems.
Any help in this regard will be greatly appreciated.
Thanks.

hi
1- for Sending commands to a PC/SC-compatible card reader with apdutool, you have to use pcsc command line option , apdutool -pcsc
you need to configure pcsc Functionality. refer to
java card dev kit2.2.2 user guide, page 10,11.
2 - The sun JavaCard Development Kit can only be used for testing applets in a simulated environment, it does not allow you to load applets to a physical card. Most cards use the GlobalPlatform specification for content management.
Best regards,
