TaskDef类Com.sun.javacard.ant.tasks.convertertask找不到

Question

i使用Netbeans中的Java卡开发套件2.2.1创建示例项目。我的代码像这样，我从https://crocs.fi.muni.cz/public/research/smartcard/javacardcompilation遵循教程。

private byte[] echoBytes;
private static final short LENGTH_ECHO_BYTES = 256;
protected TestApplet02()
{
    echoBytes = new byte[LENGTH_ECHO_BYTES];
    register();
}
public static void install(byte[] bArray, short bOffset, byte bLength)
{
    new TestApplet02();
}
public void process(APDU apdu)
{
    byte buffer[] = apdu.getBuffer();
    short bytesRead = apdu.setIncomingAndReceive();
    short echoOffset = (short)0;
    while ( bytesRead > 0 ) {
        Util.arrayCopyNonAtomic(buffer, ISO7816.OFFSET_CDATA, echoBytes, echoOffset, bytesRead);
        echoOffset += bytesRead;
        bytesRead = apdu.receiveBytes(ISO7816.OFFSET_CDATA);
    }
    apdu.setOutgoing();
    apdu.setOutgoingLength( (short) (echoOffset + 5) );
    // echo header
    apdu.sendBytes( (short)0, (short) 5);
    // echo data
    apdu.sendBytesLong( echoBytes, (short) 0, echoOffset );
}

和我的build.xml在这里。

我打扫并构建我的项目，然后得到此错误：" c： users bri documents netbeansprojects netbeansprojects testapplet02 build.xml：81：taskdef class com.sun.javacard.javacard.task.ant.tasks.tasks.convertertask不能是成立 使用classloader antclassloader []"。我应该做吗？请帮助我...

我想教程已经过时了。您可以使用Ant-Javacard的初学者尝试一种简单的方法，这是一个简单且易于理解的and build.xml工具，该工具应该与任何IDE一起使用。
