Help with Java card client
Hello All ,
i am new to javacard ...
i am using JCOP31 , and smartcard reader 5321
and implementing the java card by using Eclipse with the JCOP tools plugin
I installed an applet on a java card... and i was told that i have to write a client program to test it.
I hope some one show me how to implement a javacard Client ..and what i should do to implement a JavaCard Client .
Thank You for your time.
Hi,
Your best bet (for communicating with a real card) is to use the classes in the javax.smartcardio package in Java 6. If you search the forum you should be able to find examples of using this.
If you need to communicate with the JCOP card simulator, you will need to use the JCOP offcard API's. This is a little bit harder and you will most likely have to use trial and error (and Eclipse) to find the classes you need. I have used this in the past, but I do not have any examples of this. It was actually possible to develop a service layer that can use either API so you can switch between a real card and JCOP simulator (handy for debugging). The JCOP offcard API jar file is in the JCOP Tools plugins directory.
Cheers,
Shane

BC4J and OAS with Java Application Client
Could you show me an example about using the BC4J and OAS with Java Application client.
The JDeveloper Help is not enough to solve this kind of problem.
Configuration:
Jdeveloper 3.1
OAS 4.0.8.1
Database 7.3.4
nullif you can logon with client tools then that should be an indication that the service account running the CMS IS working! Good news.
So the problem is likely with the java portion (krb5/bsclogin or java options)
If the files are in c:\winnt\ (if not copy them there) and perform c:\program files\business objects\javasdk\bin\kinit username
then enter and password/enter again
Probably get the same message. To note in your krb5.ini all domain info must be in CAPS (the .com appears to be in lower case)
kinit works with just the krb5.ini, java SDK and AD (removing BO config and the service account from the picture). Once that works if your java options are specified properly you should be able to login to CMC/infoview.
also 1 last point. Add udp_preference_limit = 1 to the krb5 lib defaults section
libdefaults
default_realm = BD.com
dns_lookup_kdc = true
dns_lookup_realm = true
udp_preference_limit = 1

PI File adapter has a processing option u2018Empty-Message Handlingu2019 to ignore or Write Empty Files. In case there is no data created after mapping on target side then this option determines whether to write an empty file or not. But there is a catch to this option when it comes to using it with File Content Conversion which is described in SAP Note u2018821267u2019. It states following:
I configure the receiver channel with File content conversion mode and I set the 'Empty Message Handling' option to ignore. Input payload to the receiver channel is generated out of mapping and it does not have any record sets. However, this payload has a root element. Why does file receiver create empty output file with zero byte size in the target directory? Example of such a payload generated from mapping is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<ns1:test xmlns:ns1="http://abcd.com/ab"></ns1:test>
solution :
If the message payload is empty (i.e., zero bytes in size), then File adapter's empty message handling feature does NOT write files into the target directory. On the other hand, if the payload is a valid XML document (as shown in example) that is generated from mapping with just a root element in it, the File Adapter does not treat it as an empty message and accordingly it writes to the target directory. To achieve your objective of not writing files (that have just a single root element) into the target directory, following could be done:
Using a Java or ABAP Mapping in order to restrict the creation of node itself during mapping. (This cannot be achieved via Message Mapping)
Using standard adapter modules to do content conversion first and then write file.
can someone help with java mapping that can be used in this case?Hi,
You have not mentioned the version of PI you are working in. In case you are working with PI 7.1 or above then here is the java mapping code you need to add after message mapping in the same interface mapping

The code for PI 7.0 should also work for PI 7.1 provided you use the right jar files for compilation, but vice-versa is not true.
Could you please let us know if this code was useful to you or not?

Java application communicate with java card applet without java card
Can I write java application to communicate with java card applet without using java card?
Can I send APDU to java card applet on computer(not install in java card)? If it's not, how can I write?
Best Regard,
ThanawanYour JCOP simulator implements a JCVM/JCRE according
to specs. The CREF does that same thing excepts it's
only simulates the API without crypto or third party
applets. JCOP simulator is more then that. They are using thesame_ codebase for simulator and for oncard JCVM. Basically you are dealing with the same environment in both cases. -

Help with Java Printing-Custom paper sizes
Hi,
I'm trying to print documents with custom paper sizes out of java.
I can print fine when I don't try to set the MediaSize to a custom size or when I use already named constants like: "MediaSizeName.JIS_B4"
The error message I get is this:
java.lang.ClassCastException
at javax.print.attribute.AttributeSetUtilities.verifyAttributeValue(Unknown Source)
at javax.print.attribute.HashAttributeSet.add(Unknown Source)
at hello.Printy.printDocument(Printy.java:103)
at hello.Printy.main(Printy.java:135)
The offending line(103) looks like this:
pras.add(new MediaSize(1,10,MediaSize.INCH ));The function that its from looks like this:
public void printDocument()
try
System.out.println("input file name is");
System.out.println(inputFileName);
PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
PrintService printService[] = PrintServiceLookup.lookupPrintServices(flavor, pras);
PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
PrintService printPrintService = null;
// didn't work pras.add(new MediaSize(1,10,MediaSize.INCH) );
PrintService service = ServiceUI.printDialog(null, 200, 200,printService, defaultService, flavor, pras);
if (service != null)
System.out.println("There is a service aunty-may!!");
DocPrintJob job = service.createPrintJob();
FileInputStream fis = new FileInputStream(getInputFileName());
DocAttributeSet das = new HashDocAttributeSet();
//pras.add(new MediaSize((float)3.25, (float)4.75, Size2DSyntax.INCH ) );
// - works
//pras.add(MediaSizeName.JIS_B4);
pras.add(new MediaSize(1,10,MediaSize.INCH ));
//pras.add(new MediaSize(1,10,MediaSize.INCH) );
System.out.println("Doc has been set to custom size");
Doc doc = new SimpleDoc(fis, flavor, null);
job.print(doc, pras);
System.out.println("any doc for you?");
catch (Exception e)
e.printStackTrace();
}Any help with this would be greatly appreciated. I'm new to java but I've programmed a bunch in c++.Hmm ... no real help, but I found this note in the API:
MediaSize is not yet used to specify media. Its current role is as a mapping for named
media (see MediaSizeName). Clients can use the mapping method
MediaSize.getMediaSizeForName(MediaSizeName) to find the physical dimensions of
the MediaSizeName instances enumerated in this API. This is useful for clients which
need this information to format & paginate printing. -
Generate DES key with java card with JCRE 2.1.2
Hi everyone,
I want to generate DES key in my applet . my card supports GP 2.0.1 and JCRE 2.1.2 .
I have tested my applet with JCRE 2.2.1 and used this JCSystem class functions to generate DES key and it compiles and works correctlly .
but when I want to compile my applet with JCRE 2.1.2 I recieve an error which says that API 2.1.2 doesn't support JCSystem class .
so I'll really appreciate it if anyone could tell me how can I generate DES key with JCRE 2.1.2
and also I use JCSystem class functions to get my card's persistent and transistent memory , so with this class not working on JCRE 2.1.2 I have problem to read my free memories too .
So I'll appreciate your help on this matter too.
Best Regards,
VivianHi Vivian,
I don't seem to have any problem with the code you posted. What is the error you are getting? Is it with the compiler or with the CAP file converter? If it is a compiler error, you will need to ensure that the Java Card API jar is in your build path.
Here is a simple class that works with JC 2.1.1 (which will work with JC 2.1.2 as well). I have confirmed that this applet compiles and will return encrypted data to the caller.

New @ RMI need help with java.rmi.UnmarshalException: error unmarshalling
Hi @ all out there,
I'm new with Java RMI and have to write a EventSystem for an college project where clients can subscribe to a topic and get notified when someone publishes a message to the subscribed topic.
At server-side I have a class called EventSystem that provides methods for subscribing and unsubscribing from topics, and also for posting messages (for publishers).
To subscribe i thought that the client must specify the topic and also itself ( means that a client calls in this way: obj.subscribe("mytopic", this).
The EventSystem handles a list of all clients, and whenever a new message is posted it goes trough all clients and invokes the handleMessage(String msg) method that all Clients have to provide.
On my local machine without RMi this concept works just great.
I now tried to get it working using RMI , but I get the following Exception when starting the client (the server starts fine) :

So how can i do this? I've never used serialization till now.

Help with Smart Card (CAC) reader installation
Need help connecting my smart card reader to my Mac Book Pro. Either using Fire Fox, Explorer using Parallels with windows XP, or safari. I downloaded all the documentation from the Army AKO and still have problems with my Card reader.
Hi there, I have written a really good "How-to" on firefox and CAC and also Safari. You might also want to try VMware since Parallels and DoD really don't mix at this time. If yu have any question please let me know.

External Authentication with Java Card through HSM
Hi All,
How to do External Authentication process in Javacard through HSM (Hardware Security Module). Does any HSM supports this?
My requirement is to store the Card KMC in HSM and i should authenticate the terminal application with the Java Card through HSM.
Does anyone have the idea on this. Because i should not expose the Card KMC to outside world.Hi,

All the sensitive data will be able to stay secured inside the HSM. You would perform the cryptographic operations on the derivation data and store the result as a key object inside the HSM. There is quite a lot of documentation on the PKCS11 operations on the RSA web site.

Help with JAVA StringObject - & assign user input; StringMethod
Hi Everyone! I need help with this Java Program, I need to write a program, single class, & file. That will prompt the user to enter a word. The output will be separted by hypens and do this until the user enters exit. I think this is done by using a string variable. Then use the length of the word to setup a loop to print each letter out with hypens. (example c-a-t)
1. I think I should store the word like this: Word.Method(). Not sure of this the API was confusing for me because I wasn't sure of what to do.
2. A string method to find out how many letters are in the user's word in order to setup a loop to print each letter out. I think I can use a While loop to accomplish this?
3. A string method to access each letter in a string object individually in order to print individual letters to the screen with those hypens. This is really confusing for me? Can this be accomplished in the While loop? or do I declare variables in the main method.
Any examples you can refer me to would be greatly appreciated. ThanksGetting user input:
This may look strange to a newbie but there's nothing much you can do since you wanted a single class file:import java.io.*
public class InputTest {
public static void main(String[] args) {
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.println("Hi! Please type a word and press enter.");
String lineReadFromUser = in.readLine();
System.out.println("You typed " + lineReadFromUser);
}You can get the lenght of a String using the length() method. Example: int len = "Foobar".length();
You can get the individual characters of a String with the charAt() method. Example: char firstCharOfString = string.charAt(0);
(remember that the argument must be from 0 to length-1)
You can access the documentation of all classes, including java.lang.String, at http://java.sun.com/j2se/1.3/docs/api/index.html You can also download the docs. -
I need some help with some Java assignments. I'm new to it, and I am having some problems.
People will help you - if you help them first by stating your problem. If it was a generic question wanting to know wether anyone will help you at all - the answer is yes, they would - you have to put your work in first however.

Hi everybody,
I have a simple Java application that has a JFrame containing a TextField displaying some text inside it. I am using the NetBeans IDE. I am trying to Enable Java Web start for this application. The steps I have taken upto now are:
1. Right click on Project, Java Web Start -> Enable Java Web Start. This created the jnlp file.
2. In the Resources section, I added the jar file for swing. ( I am not sure if I have to add the path for jnlp.jar etc, or are these found automatically?)
3. Right click on Project, Java Web Start -> Deploy with Java Web Start. This launches the browser with the Click me link, but on clicking this link, I get the following error.
description The server encountered an internal error () that prevented it from fulfilling this request.

java.lang.Thread.run(Thread.java:534)I have all the jnlp files in my jdk directory, and I am not sure why it can't find it. Is there something I am missing?
Thanks
GeorgeI am not sure what it has to do with servlets, I just followed a tutorial on using Netbeans with Java Web Start, and did only the steps as mentioned in my first post. And ended up with the error.
Anyways, I added the jnlp jar files(jnlp.jar, jnlp-servlet.jar, jardiff.jar) in the WEB-INF/lib directory. And it seems to deploying it now. I can get my application to load on clicking on the "Click me" link. But the controls on my application don't seem to be working.
Also, when I try to Right click on my project -> Java Web Start -> Run with Java Web Start, I get the following error message,
javaws-run: C:\Documents and Settings\Lux\Visualization\nbproject\build-jaws-impl.xml:36: Execute failed: java.io.IOException: CreateProcess: C:\j2sdk1.4.2_13\bin\javaws "file:///C:/Documents and Settings/Lux/Visualization/Visualization.jnlp" error=2
BUILD FAILED (total time: 0 seconds)
Any help appreciated.
Thanks.
George
