Running jcardsim with eclipse: java.lang.IllegalArgumentException: wrong number of arguments

[iSecurus]

Hey, when I try to include jcardsim into my project for debug reasons, i got the following error:

Exception in thread "main" java.lang.RuntimeException: Internal reflection error at com.licel.jcardsim.base.SimulatorRuntime.(SimulatorRuntime.java:95) at com.licel.jcardsim.base.SimulatorRuntime.(SimulatorRuntime.java:75) at com.licel.jcardsim.smartcardio.CardSimulator.(CardSimulator.java:44) at test.DebugMain.main(DebugMain.java:18) Caused by: java.lang.IllegalArgumentException: wrong number of arguments at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at com.licel.jcardsim.base.SimulatorRuntime.(SimulatorRuntime.java:85) ... 3 more

My setup is:

• I added jcardsim to the classpath of my Eclipse project, right behind the api_classic.jar. Also I added the asm-all-XXX.jar to the project.
• I created a seperate DebugMain class, running the given code from the quick start guide on jcardsim.org:

// 1. Create simulator CardSimulator simulator = new CardSimulator();

// 2. Install applet AID appletAID = AIDUtil.create("F000000001"); simulator.installApplet(appletAID, HelloWorldApplet.class);

// 3. Select applet simulator.selectApplet(appletAID);

// 4. Send APDU CommandAPDU commandAPDU = new CommandAPDU(0x00, 0x01, 0x00, 0x00); ResponseAPDU response = simulator.transmitCommand(commandAPDU);

// 5. Check response status word assertEquals(0x9000, response.getSW());

• I created an applet and the corresponding jcardsim.cfg-file needed for BixVReader

With this setup i have tried differnt jcardsim versions (2.2.2, 3.0.4, 3.0.5) combined with different java versions (1.5, 1.6, 1.8) and java card versions (2.2.2, 3.0.2, 3.0.5) and created two debug configurations within eclipse:

• The first configuration uses the DebugMain as entry point and fails while creating the CardSimulator.
• The second configuration uses the BixVReaderCard-main as entry point and also the cmdline arguments used to start jcardsim (as VM and Program Arguments). Running this from plain cmdline, without using eclipse, will succeed. Using it whitin the eclipse debug configuration will fail with the errors shown above.

My reserach resulted in the knowledge, that jcardsim should use the implemented APDUProxy.class, which needs an argument when calling the constructor. But when running it with Eclipse, it will load the normal APDU.class and fails with "IllegalArgumentException". But I have no idea how to fix this. Also it is curious, that everything works fine, when using the cmdline to run jcardsim.

Is there something missing in the configuration or do I miss something else? How can I configure jcardsim to run in the eclipse debugger finally?

The problems were caused by the api_classic.jar in the classpath and later on by the missing -noverify-flag. After removing the user classpath completely from the Debug-Configuration, re-adding the jar file for jcardsim and the -noverify option to the VM arguments everything works fine!
