Eclipse 3.1

Question

hello there. I am using eclipse 3.1.Below is my code:
package com.acme.helloword;
import javacard.framework.APDU;
import javacard.framework.Applet;
import javacard.framework.ISO7816;
import javacard.framework.ISOException;
public class HelloWorldAppet extends Applet {
     // codes of CLA bytes in the command APDUs
     final static byte Helloword_CLA= (byte) 0xB0;
//     codes of INS bytes in the command APDUs
     final static byte VERIFY =(byte) 0x20;
     public static void install(byte[] bArray, short bOffset, byte bLength) {
          // GP-compliant JavaCard applet registration
          new HelloWorldAppet().register(bArray, (short) (bOffset + 1),
                    bArray[bOffset]);
     public void process(APDU apdu) {
          if (selectingApplet()) {
               return;
          byte[] buf = apdu.getBuffer();
          if(buf[ISO7816.OFFSET_CLA] !=Helloword_CLA )
               ISOException.throwIt(ISO7816.SW_CLA_NOT_SUPPORTED);
          switch (buf[ISO7816.OFFSET_INS]) {
          case VERIFY:               
               break;
          default:
               ISOException.throwIt(ISO7816.SW_INS_NOT_SUPPORTED);
when i am running this code in the simulation and send B020 i am getting 0x9000;
but when i am testing it in the card i am getting
jcshell: Error code: -6 (Card terminal error)
jcshell: Communication problems: The parameter is incorrect.
why i am getting this error?
Finally, can i get an ID number when i send B020?
Thank you
