Help in starting Java Card Programming

Hi all,
I�m totally new here. I just started Java Card programming. However I don�t know how to start though I think I have enough stuff. I have installed Java 1.6.0_02, JCOP tool 3.1.2, run Eclipse 3.3.0. I also have a dual interface smart card reader SDI010 and some smart card (dual access). I activated JCOP Tool, created new Java Card project, but after I entered package AIDs and applet AIDs I don�t know what I should do next. I looked through several books in Eclipse (Eclipse for dummies�) but can�t find anything about Java Card. Anyone have experience in this area please help me to start. If you know any document that guides step by step, please let me know. I found source code in Sun website (wallet.java) but I really don�t know how to use it. Thanks a lot.

Hi,
select
Project -> Build Automatically. It will build a .CAP file every time you changed your Java Card project code and save it. You will see it in the
CAP file viewer in the left corner (but only in case you are developing your JC applet in Java Card in Eclipse project and opened one of the
JCOP perspectives: either development or debug).
P.S. I suppose, that u still haven't looked through the JCOP tools documentation in the Eclipse IDE Help menu.
Best regards,
Eve

How should i start Java Card Programming?

Hi All,
I am a j2me programmer and now would like to learn and develop some applications in JavaCard Technology. but the problem is i dont know how should i start with JavaCard Programming?What all hardwares and softwares will i require for doing JavaCard programming?Can anyone give me some project ideas too for programming in JavaCard Technology
Thanks
Sagar

I think it's best you start here:
http://java.sun.com/products/javacard/index.jsp
Some hints about books/specs you can find in this post:
http://forum.java.sun.com/thread.jspa?forumID=23&threadID=5114170
There are a variety of Java Card development tools. Just browse through this forum.

Need suggestions to start java card prog. plz help!!

hi ppl....
I am new to java card programming, but not to java programming. As a starter, i need to know ..... how to write a basic java card app?? Further, i also want to get the knowledge of testing/running this app on any simulator (if available). Can someone tell me that if i need to run my card application on real "smart card" (NOT on simulator), then what i need to have ... i mean any card processor or interface with PC. Any help will be much appreciated.

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,

Naveed

please post code with {code} tags

How to start java card development?

Good Evening all,
I am novice for java card development , from last some days I study java card and terms related to it, now i have some knowledge about applets , and API. as i read about java card 2 and 3, I think i moved to java card 2 that's why i download jcdk 2.1.
Now i want to do something in development rather than further conceptual study. Frankly speaking I m confused where to move because different sites have different point of view so i want to execute my knowledge which i earned from last some days...
so I want to ask
1- which IDE would be best for java card development? { eclipse or net beans or something other}
2- what things i would be require during java card application?{ java sdk version? jcdk version? ocf? or what}
3- at start i want to use simulation technique to test what i made and how its work, so for this which tool or IDE would be best work for me,
so kindly request you to guide me and show me the path where i can move and achieve what i want..
---------------------------------------------------------------------------------------------------Thank you in advance------------------------------------------

Hello umer,
last night it seems very tough to execute sample program of jcdk 2.2 but finally i make it, and i also i got the IDE - net beans that is very good for java card...
I think i should share my knowledge here for next novice people...
----------------------------------------------------------------------------java card development require-------------------------------------------------------------
Because here we use java for java card so we require
1- java development kit (JDK) - use below link to get this.
[get jdk here|http://download.oracle.com/otn-pub/java/jdk/6u30-b12/jdk-6u30-windows-i586.exe]
2- Java card require java card development kit (JCDK) I think java card version 3 is latest but i used jcdk 2.2.1
[get jcdk here|http://download.oracle.com/otn-pub/java/java_card_kit/2.2_01/java_card_kit-2_2_01-win-gl.zip]
now i think this is enough to start java card development...
follow below steps
1- install jdk 6 in c:/java/jdk1.6
2-keep jcdk in c:/java_card_kit-2_2
3- open command prompt and run
a)-set JC_HOME=c:\java_card_kit-2_2
b)-set JAVA_HOME=c:\java/jdk1.6
c)-set PATH=%JC_HOME%\bin;%PATH%
4-there are some sample project in scdk, if you want to get confidence , u should run one of them..
run command- jcwde jcwde.app { jcwde is a simulator where u check what u made }
and run this command in another command prompt- apdutool -nobanner -noatr demo1.scr > demo1.scr.jcwde.out
You can get detail of 3 and 4 step from cJDK_Users_Guide.pdf which is present in jcdk.
------------------------this is all which u need to do to get confidence in java card, but dont be over confident because in reality "the ball is not in your court yet"
Note- if you are searching which java IDE is best for java card development then
[click here- this is one of the best ide for java card|http://dlc.sun.com.edgesuite.net/netbeans/7.1/final/bundles/netbeans-7.1-ml-windows.exe]

How to run the simple java card program in eclipse?

I am trying to run a simple HelloWorld program in eclipse 3.5 having java card development kit 2.2 installed in it.
Firstly,I go to the JCWDE tab and press start..then when trying to deploy that package its giving me error like " com.hw.HelloWorld: unsupported class file format of version 50.0." can any one help me in this what is this error???n how to resolve n run this program..

Hi,
It is because the converter works on byte code and it only supports a subset of the Java language (see the JC specifications). It is kind of like compiling you code on Java 6 and trying to run it on Java 5. The JCDK outlines the required compiler version.
Cheers,

How to start with Card programming !

Hello,
I want to learn card programming. For this i want to know few things.
1) Where can i find an IDE to write program ?
2) Do we get any simulator in it ?
3) How to compile and run the card program.
Right now i can not buy a reader or card. Just want to develop in simulator. How to start ?
Please, help me. I do not know anything about it.
Thanks,
Abhijit Chandekar

I want to learn card programming.http://developers.sun.com/techtopics/mobility/javacard/articles/
Read "An Introduction to Java Card Technology" Part 1 to 3 for starting with java cards.
1) Where can i find an IDE to write program ?The JCOP tools plugin for Eclipse is the cheapest IDE i know.
http://www.zurich.ibm.com/jcop/products/tools.html
2) Do we get any simulator in it ?Use CREF from the Java card development Kit or the JCOP emulator from the JCOP tools.
3) How to compile and run the card program.See the Java Card Development Kit User’s Guide that comes with the Java Card JDK.
@the other forum member:
May be we should start creating a forum-FAQ which will be posted once a week. That would make it easier to help all the "newbies"...
Someone interested?

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.

Why do we need IDE or tools for java card programming?

Hi,
I am a newbie to java card, using java card kit tools themself, we can test and burn the code into card right?
then why do we need IDE for java card, please correct me , if i am wrong,
Thanks in advance,
Sri.

Dear Sri,
We have compiler, linker etc for every language starting of from C or C++ or Java. JDK has all the tools necessary to develop and run a Java program. Similarly Java Card Development Kit has all the tools for developing and deploying a Java Card applet. But what an IDE does is too integrate all these tools and make it easier for the JavaCard programmer to develop his applets. Just like Eclipse is used for Java applet development.And not everytime the code is burned to the card. Its only during masking code is burned to the card, i.e if u can call it burning. Masking makes an applet permanent on the card.

Regarding java card programming

hi all,
i am very new to the java card tech. now i want to do a project in the smart card area. how can i ready to programming (downloadables)? i need some basic idea about tools to be downloaded. please provide me some ideas.
Thanks and Ragards

Start with something more simple. You're just asking
for trouble trying to start with something "big".Agreed. You may want to make a non-AI version of the game first. In other words, if you want to make a game of blackjack with an AI dealer. First make the blackjack game with no AI. So the user would deal his own cards and decide when to hit, stand, etc... After you understand how to let the player do that, you can move on to dealing with how a computer would do it.

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.
regard,

UPDATED: jcManager - Java Card Programming Visual Tool

UPDATED with the following features, as requested:
- new and improved GUI
- possibility to select the reader
- better output - display all commands sent to card and the replies
- specify card manager AID
- specify applet install command parameters
... and many more

... sorry for the double post...

Thanks Stefan for your reply..
i want to know, what versions of Java Card OS that supported by jcManager..
Currently i use Java Card 2.2.1, but when i tried to load .CAP file using this tool, i always get this error :
Open terminal ...

Thanks everybody for their contribution and suggestion. I have been able to make the demo works apart from demo1 which still give problems.

Auto start Java Card application

Hello,
is it possible to start a Java Card application from the SIM card right after the mobile is switched on?
I talked to a guy from a SIM card manufacturer and he told me it's possible since the device checks on start if a Java Card application is present to display it in the phone's menu, but it's device dependant how it's done and if the application really will be started (which sounds kind of strange).
Can someone give me more details if it's possible to auto start a application and how it's done ( code snippet would be great ; )?
Thanks in advance,
teric

The first event after ME startup, which STK applet could catch is Terminal Profile.
So, in applet class constructor should be smthng like
ToolkitRegistry reg = ToolkitRegistry.getEntry();
reg.setEvent(EVENT_PROFILE_DOWNLOAD);
and applet will trigger on Terminal Profile arrival.
