JCOP20 card too old and Samples for JCOP Offcard API (RMI)
Hi all!
I have two problems/questions in which you might be able to help me.
I plan to develop a Java Card application which uses the JC-RMI api and an according Offcard application which uses the JCOP Offcard RMI API.
I have Eclipse 3.1 and JCOP Tools 3.1 for that.
To try my setup, i decided to use a sample application. I took the Purse application from the java card dev kit 2.2.1, which uses RMI and OCF in the offcard app. I tried it out with the JC Simulator included in the JCOP tools - the upload of the applet worked. First problem - how can i test the offcard application (how to configure OCF to use the simulator on port 80xx something)?
Second (much worse) problem: For my project, i have java cards which i bought at this shop: http://www.cardomatic.de/start.htm?java_smart_cards.htm
I have the JCOP20 card. When trying to upload the applet to the card, i got this:
<= 6A 80 j.
Status: Wrong data
jcshell: Error code: 6a80 (Wrong data)
jcshell: Wrong response APDU: 6A80
Unexpected error; aborting execution
As setting for the card, i took "jcop engineering sample", because i didn't know what to do - can the problem rely on this step or is the card not capable of what I'm planning to do?
Another problem I have is that I cannot find any sample code for the JCOP offcard api, which means I really don't know how to start my offcard application. Can someone provide me with some examples? The best thing would be a sample application with the use of jcop offcard rmi api.
Thanks in advance for your replies! It's very much appreciated!
Matthias

You can use the "WrapperFactory" posted in the thread "OCF and Java Card Applet":

That is a JavaCard 2.1.2 card. You won't succeed in using it with JC-RMI. You need a JavaCard 2.2.1 card like the new JCOP41v2.2 card if you want to use JC-RMI.

My be this sample code helps you:
import com.ibm.jc.JCApplet;
import com.ibm.jc.JCTerminal;
import com.ibm.jc.JCard;
import com.ibm.jc.rmi.RMIObjectFactory;
public class JcopTest {
public static void main(String[] args) {
try {
//connect to the JCOP emulator on port 8050
JCTerminal terminal = JCTerminal.getInstance("remote",null);
terminal.open();
JCard card = new JCard(terminal,null,0);
JCApplet applet = new JCApplet(card,"myaid".getBytes());
applet.select();
// get the first CardRemoteObject from the card
Object o = RMIObjectFactory.getInitialReference(applet);
MyInterface i = (MyInterface) o;
//i.callMethodeViaRMI(..)
} catch (Exception e) {
e.printStackTrace();
}
}
}
