How to load the .cap file in a Smart Card?

Question

Dear All,
Hello..!!
I am using JCDK 2.2 and have used Eclipse JCDK.
I have written a simple read/write applet and created a .cap file using Eclipse's Converter Java Card tool.
What is the next step to be done?
I have a smart card device and have installed its drivers.
When do the APDU commands come into picture?
Expecting help.
Thanks a lot.
Regards,
Suril

One more thing Shane......
I'm writig a java class using javax.smartcardio
I have installed drivers of Omnikey 3021
but the TerminalFactory is not detecting it?
Any idea on that?
Thanks again...

SurilHi all,
Is Mr. thread starter has solved his problem?
I profit this thread to post my question. I'm working with new environment and I have problem loading cap file into my smartcard.
specification come first :-)
- My smartcard is said to be JC2.2.1 and GP2.1.1 compatible
- My code (for testing) is written in Java under eclipse Helios service 2 with JavaCard plugin (for JC2.2.2)
I compile my code with JDK 1.3 (for compatible version) and using the JC plugin to generate cap file (along with exp and jca).
My problem is exactly the same as one that was posted in this forum about 2 years ago but is not answered :-)

+ I successfully authenticate with smartcard
+ APDU command Install for Load is executed successfully
+ BUT the APDU command LOAD file fails with returned status word is 6424
For details, I post here my javacard applet code and APDU command executed with my tool:
package mksAuthSys;
import javacard.framework.APDU;
import javacard.framework.Applet;
import javacard.framework.ISO7816;
import javacard.framework.ISOException;
import javacard.framework.OwnerPIN;
public class Jcardlet extends Applet {
     private final static byte[] myPIN = { (byte) 0x01, (byte) 0x02, (byte) 0x03, (byte) 0x04};
     final static byte Jcardlet_CLA =(byte)0xB0;
     final static byte VERIFY = (byte) 0x20;
     final static byte PIN_TRY_LIMIT =(byte)0x03;
     final static byte MAX_PIN_SIZE =(byte)0x08;
     final static short SW_VERIFICATION_FAILED = 0x6300;
     OwnerPIN pin;
     private Jcardlet() {
          pin = new OwnerPIN(PIN_TRY_LIMIT, MAX_PIN_SIZE);
          pin.update(myPIN, (byte) 0, (byte) 4 );
         register();
     public static void install(byte bArray[], short bOffset, byte bLength)
               throws ISOException {
          new Jcardlet().register();
     public boolean select() {
          if ( pin.getTriesRemaining() == 0 ) return false;
         return true;     
     public void deselect(){
          pin.reset();
     //@Override
     public void process(APDU apdu) throws ISOException {
          // TODO Auto-generated method stub
          byte[] buffer = apdu.getBuffer();
          if ((buffer[ISO7816.OFFSET_CLA] == 0) &&
                  (buffer[ISO7816.OFFSET_INS] == (byte)(0xA4))) return;          
          if (buffer[ISO7816.OFFSET_CLA] != Jcardlet_CLA)
                ISOException.throwIt(ISO7816.SW_CLA_NOT_SUPPORTED);          
          switch (buffer[ISO7816.OFFSET_INS]) {
           case VERIFY: verify(apdu);
             return;
           default: ISOException.throwIt (ISO7816.SW_INS_NOT_SUPPORTED);
     private void verify(APDU apdu) {
          // TODO Auto-generated method stub
         byte[] buffer = apdu.getBuffer();
         // retrieve the PIN data for validation.
         byte byteRead = (byte)(apdu.setIncomingAndReceive());
         // check pin
         // the PIN data is read into the APDU buffer
         // at the offset ISO7816.OFFSET_CDATA
         // the PIN data length = byteRead
         if ( pin.check(buffer, ISO7816.OFFSET_CDATA,byteRead) == false )
           ISOException.throwIt(SW_VERIFICATION_FAILED);          
}And my APDU command:
