我刚刚创建了一个非常简单的applet.这是 Java卡技术中的“hello world”.我粘贴了下面的代码.
public class helloworld extends Applet {
private byte[] echoBytes;
private static final short LENGTH_ECHO_BYTES = 256;
/**
* Installs this applet.
*
* @param bArray
* the array containing installation parameters
* @param bOffset
* the starting offset in bArray
* @param bLength
* the length in bytes of the parameter data in bArray
*/
public static void install(byte[] bArray, short bOffset, byte bLength) {
new helloworld();
}
/**
* Only this class's install method should create the applet object.
*/
protected helloworld() {
echoBytes = new byte[LENGTH_ECHO_BYTES];
register();
}
/**
* Processes an incoming APDU.
*
* @see APDU
* @param apdu
* the incoming APDU
*/
@Override
public void process(APDU apdu) {
//Insert your code here
//
byte buffer[] = apdu.getBuffer();
if ((buffer[ISO7816.OFFSET_CLA] == 0) && (buffer[ISO7816.OFFSET_INS] == (byte) (0xA4))){
return;
}
short bytesRead = apdu.setIncomingAndReceive();
short echoOffset = (short) 0;
Util.arrayCopyNonAtomic(buffer, ISO7816.OFFSET_CDATA, echoBytes, echoOffset, bytesRead);
echoOffset += bytesRead;
apdu.setOutgoing();
apdu.setOutgoingLength((short)(echoOffset + 5));
//echo header
apdu.sendBytes((short) 0, (short) 5);
//echo data
apdu.sendBytesLong(echoBytes, (short) 0, echoOffset);
}
}
之后我决定使用Global Platform将它安装在真实卡(J3A081)上,但它失败了.
首先,我检查了卡上是否已安装任何applet并带有命令：
java -jar gp.jar -l
回应是：
AID: A000000003000000 (|........|)
ISD OP_READY: Security Domain, Card lock, Card terminate, Default selected, CVM (PIN) management
当我决定使用* .cap文件安装applet时,我得到了：
java -jar gp.jar -install krystian.cap

你能告诉我我做错了吗？这张卡是全新的,从未使用过.我正在使用ACR122U NFC读卡器和NXP卡J3A081.
编辑
经过几个小时的尝试,我设法做了几件事.首先,我更新了ACR122U智能卡读卡器的驱动程序.此外,我熟悉GPShell并创建了一个简单的脚本：
mode_211
enable_trace
establish_context
card_connect

card_disconnect
release_context
哪个输出：

所以我想一切正常,但是当我想用这个安装applet时：
mode_211
enable_trace
establish_context
card_connect
select -AID a000000003000000
open_sc -security 1 -keyind 0 -keyver 0 -mac_key 404142434445464748494a4b4c4d4e4f -enc_key 404142434445464748494a4b4c4d4e4f
install -file helloworld.cap -nvDataLimit 2000 -instParam 00 -priv 2
card_disconnect
release_context
我有一个例外：

我终于设法在我的卡上安装了applet.我使用修改过的GlobalPlatformPro,正如vlp所写,有必要将加载块更改为16个字节.但我只能安装hello world applet,在处理我的时候,GlobalPlatformPro返回异常：
java -jar gp_16byteLoadBlock.jar --install inzynierka.cap pro.javacard.gp.GPException: LOAD failed SW: 6A80 at pro.javacard.gp.GlobalPlatform.check(GlobalPlatform.java:1092) at pro.javacard.gp.GlobalPlatform.loadCapFile(GlobalPlatform.java:728) at pro.javacard.gp.GlobalPlatform.loadCapFile(GlobalPlatform.java:686) at pro.javacard.gp.GPTool.main(GPTool.java:453)最佳答案 (评论中的讨论记录)
事实证明,ACR122U NFC读卡器存在长APDU的问题(也提到了here).
可能的解决方案之一是以下列方式修改GlobalPlatformPro工具：
>获取来源here
>找到在GlobalPlatform.java:724检索加载文件块的代码部分
>通过用一些较小的常量替换wrapper.getBlockSize()部分来减少加载块大小(确认32工作,确认64不能使用此读取器)
>重新编译GlobalPlatformPro编辑>
最新的GlobalPlatformPro代码adds a -bs选项,允许您设置块大小而无需重新编译.
