How can I use the security package in JCOP41V2.2?

Question

Hi all, I'm a newbie in javacard programming. I'm trying to develop a project with RSA_signature. But I found, the exception NO_SUCH_ALGORITHM will be thrown out when I new an instance of KeyPair.
My java file Temp_1.java following:
package temp;
import javacard.framework.Applet;
import javacard.framework.ISO7816;
import javacard.framework.ISOException;
import javacard.framework.APDU;
import javacard.security.*;
* @author lujj
public class Temp_1 extends Applet {
KeyPair myKeyPair = null;
     public static void install(byte[] bArray, short bOffset, byte bLength) {
          // GP-compliant JavaCard applet registration
          new Temp_1().register(bArray, (short) (bOffset + 1), bArray[bOffset]);
     public void process(APDU apdu) throws ISOException{
          // Good practice: Return 9000 on SELECT
          if (selectingApplet()) {
               return;
          byte[] buf = apdu.getBuffer();
          if(buf[ISO7816.OFFSET_CLA] == (byte)0xEE)
               try
                    myKeyPair = new KeyPair(KeyPair.ALG_RSA, KeyBuilder.LENGTH_RSA_1024);
               catch(CryptoException e)
                    ISOException.throwIt((short)(0x6F00+e.getReason()));                    
               return;
          switch (buf[ISO7816.OFFSET_INS]) {
          case (byte) 0x00:
               break;
          default:
               // good practice: If you don't know the INStruction, say so:
               ISOException.throwIt(ISO7816.SW_INS_NOT_SUPPORTED);
This package can be upload and the applet can be installed successfully.
But if I send the apdu "EE 00 00 00 00" after selected the applet, "6F 03" will be returned.
Is there anyone can help me? Thanks a lot.

Thank you so much~
Actually, it's only an applet for test. I cannot get the error code if I new the KeyPair in install function or Applet construct function. It will return "6A 80" when install the applet.
And, I found that it support few algorithm. For example, it does not support ALG_DES_MAC4_ISO9797_M2,etc. Is there anything I can do if I want to use the algorithm? Shall I rewrite security package by myself?
5555, security package is the standard package in JAVACARD API 2.1.1.
