Java卡小程序安装过程中收到6700状态字错误

我想向JavaCard applet发送一个随机字节数组（例如，包括24个元素），然后我的applet应该使用特定的方法更改该数组。例如，该方法使用0x05对每个元素进行异或，并在APDU响应中返回结果数组。

为了实现上述目标，我编写了以下程序：

package keyGeneratorPackage;

import javacard.framework.APDU;
import javacard.framework.ISO7816;
import javacard.framework.Applet;
import javacard.framework.ISOException;
import javacard.framework.JCSystem;
import javacard.framework.Util;

public class KeyGeneratorPackage extends Applet {
    private static final byte HW_CLA = (byte) 0x80;
    private static final byte HW_INS = (byte) 0x00;

    public static void install(byte[] bArray, short bOffset, byte bLength) {
        new keyGeneratorPackage.KeyGeneratorPackage().register(bArray, (short) (bOffset + 1),
                bArray[bOffset]);
    }

    public void process(APDU apdu) {
        if (selectingApplet()) {
            return;
        }
        apdu.setIncomingAndReceive();
        byte[] buffer = apdu.getBuffer();
        byte CLA = (byte) (buffer[ISO7816.OFFSET_CLA] & 0xFF);
        byte INS = (byte) (buffer[ISO7816.OFFSET_INS] & 0xFF);
        short  lc =  (short) (buffer[ISO7816.OFFSET_LC] & (short)0x00FF); 
        byte[] Data = JCSystem.makeTransientByteArray(lc, JCSystem.CLEAR_ON_DESELECT);

        if (CLA != HW_CLA) {
            ISOException.throwIt(ISO7816.SW_CLA_NOT_SUPPORTED);
        }
        switch (INS) {
        case HW_INS: {
            // copying the apdu data into byte array Data
            Util.arrayCopy(buffer, ISO7816.OFFSET_CDATA, Data, (short) 0, lc);
            getKey(apdu, Data);
        }
        break;
        default:
            ISOException.throwIt(ISO7816.SW_INS_NOT_SUPPORTED);
        }
    }

    private void getKey(APDU apdu, byte[] data) {
        byte[] buffer = apdu.getBuffer();
        short length = (short) data.length;
        //prepareing the key array of same length of Data
        byte[] key = JCSystem.makeTransientByteArray(length, JCSystem.CLEAR_ON_DESELECT);
        generateKey(data, key);

        Util.arrayCopyNonAtomic(key, (short) 0, buffer, (short) 0, (short) length);

        apdu.setOutgoingAndSend((short) 0, length);
    }

    private byte[] generateKey(byte[] Data, byte[] key) {
        short i;
        for (i = 0; i < Data.length; i++) {
            key[i] = (byte) (Data[i] ^ (byte)0x05); 
        } 
        return key;
    }

}

我必须在编译并选择我的小程序后发送以下APDU命令：

<代码>>>80 00 00 00 00 18 11 22 33 44 55 66 88 99 10 20 30 40 50 60 70 80 90 b1 b2 b3 b4 b5 b6 b7 B8

并且我的applet必须返回的预期数据是：

<<< 14 27 36 41 50 ... bd

我安装这个小程序有问题。

我不能安装它到我的Java卡，而我确信没有问题的Java卡版本兼容我的小程序和我的卡。无论如何，我的程序是用Java卡开发工具包2.2.1编译的。

值得注意的是，我创建了一个默认的Java卡项目，没有任何额外的代码，它成功地安装在我的卡上。它也是由JavaCard Development kit Version2.2.1编译的。

我使用globalPlatformPro安装我的applet时，它在状态词中给了我0x6700错误。

我输入了带有-v-d参数的install命令。输出为：

我可以安装我的小程序在我的智能卡上成功，但通过gpj平台。在gpj平台上安装的输出为：

我无法通过GlobalPlatformPro，在智能卡上安装我的applet。我不知道原因，反正在这个平台上安装命令的输出是：

        apdu.setIncomingAndReceive();
