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,
Regards,
Naveed

please post code with {code} tags

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 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.

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.

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 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.

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.

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
__Vasantha kumar

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.

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
[Download here|http://www.brokenmill.com/2010/03/java-secure-card-manager/]
Enjoy
Stefan
... 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 ...

Java 3D Program execution Exception

Hello,
I installed Java 3D, and tried running the example from j2sdk1.4.0\Demo directory.The program is getting compiled, but when I try executing using 'java' command I get the error
Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\Program Files\Java
\j2re1.4.0\bin\J3D.dll: One of the library files needed to run this application
cannot be found.
I tried to introduce C:\Program Files\Java\j2re1.4.0\bin in classpath and path but still the problem exists.
Please tell me how to proceed.
Thanks in Advance

Did you verify that the DLL is there? The problem you are getting is that somewhere a JNI call is making a native call (System.loadLibrary()) on a native DLL, and it either cannot find the file, or there is a security error. Are you running an applet?

Java card help

Hello. i am new in Java card programming and i need some help.
I have installed eclipse 3.1 j2sdk1.4.2_09, javacard kit , comm api and some plugins. I buy the license from ibm and i took a jcop 2.2 card.
i have 3 questions...
a) can i program this card?
b) I should install jpcsc? Where i must put this folder?
c) is there any simple tutorial with wich i can see if all the stuff is ok?
Thanks

a) can i program this card?Yes, but you shpuld be carful not to terminate the card (because your license would then be terminated, too).
b) I should install jpcsc? Where i must put this
folder?No, JCOP includes JPCSC. Just in the lib directory of the jcop plugin. There you find all neccessary jar-files.
c) is there any simple tutorial with wich i can see
if all the stuff is ok?Search this forum.

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.

Here are the steps that we used to create the Oracle Concurrent Program:
1. First of all we wrote a Java class that implements oracle.apps.fnd.cp.request.JavaConcurrentProgram
rac.oracle.apps.qot.quote.batch.SFDCInterface implements JavaConcurrentProgram
2. The concurrent program has a method called public void runProgram(CpContext pCpContext) which has the logic to be executed.
3. Then we create a concurrent program executable
Path: Concurrent -> Program -> Executable.
Executable: RAC Quoting SFDC Sync Executable
Short Name: RacQotSFDCSyncEx
Application: Quoting
Description: RAC Quoting SFDC Synchronization batch program
Execution Method: Java Concurrent Program
Execution File Name : SFDCInterface
Execution File Path : rac.oracle.apps.qot.quote.batch
4. Create the Concurrent Program
Path: Concurrent -> Program -> Define
Program: RAC Quoting SFDC Sync CP
Short Name: RACQOTSFDCSYNCCP
Application: Quoting
Description: RAC Quoting SFDC batch Synchronization Concurrent Program
Executable: Name - RacQotSFDCSyncEx; Method - Java Concurrent Program
5. This concurrent program is registered with a custom responsibility from which we run this concurrent program.

Please post the details of the application release, database version and OS.
We are creating a Java Concurrent Program which is using third party web service. The client classes for the webservice have been placed in a jar file. This jar file has been added to the SYSTEM CLASSPATH. When we try to run the concurrent program it fails with a ClassNotFoundException giving the name of the webervice client. The webservice clients are being used by other java classes from OAF as well. From there it is easily accessible.Please post the contents of the concurrent request log file here. You may also enable trace and submit the request again and post the contents of the log file.

As for the IDE, you can use Ecplise with the Java Card Plugin:
http://www.eclipse.org/downloads/
http://eclipse-jcde.sourceforge.net/
Of course, you will also need the Java Card Development Kit:
