我研究了如何使用 Sun PKCS#11 api 访问 DoD CAC 并可能使用 CAC 访问（只读）Active Directory。我的问题是，我发现在大多数情况下会引用一些代码，但从不显示引用的代码。我找到了以下代码，但给出了错误。有谁知道将 PKCS11 用于 CAC 的任何代码示例或清晰的文档？或者可能有效的 API 解决方案？

import java.io.*;
import java.util.*;
import java.security.cert.CertificateException;
import java.security.KeyStoreException;
import java.security.cert.X509Certificate;
import java.security.KeyStore;
import java.security.Provider;
import java.security.Security;


public class SmartCard {
    public static void main(String[] args) throws Exception {
        try {
            String configName = "pkcs11.properties";
            Provider p = new sun.security.pkcs11.SunPKCS11(configName);
            Security.addProvider(p);
            Console c = System.console();
            char[] pin = c.readPassword("Enter your PIN: ");
            KeyStore cac = null;
            cac = KeyStore.getInstance("PKCS11");
            cac.load(null, pin);
            showInfoAboutCAC(cac);
        }
        catch(Exception ex) {
            ex.printStackTrace();
            System.exit(0);
        }
    }
    public static void showInfoAboutCAC(KeyStore ks) throws KeyStoreException, CertificateException {
        Enumeration<String> aliases = ks.aliases();
        while(aliases.hasMoreElements()) {
            String alias = aliases.nextElement();
            X509Certificate[] cchain = (X509Certificate[]) ks.getCertificateChain(alias);
            System.out.println("Certificate Chain for " + alias);
            for(int i = 0; i < cchain.length; i++) {
                System.out.println(" -SubjectDN: " + cchain[i].getSubjectDN());
                System.out.println(" -IssuerDN: " + cchain[i].getIssuerDN());
            }
        }
    }
}

属性文件确实存在，并且与应用程序位于同一目录中。据我所知，Java 可以访问该文件。

如果有帮助，这是文件的内容：

name=SmartCard
library=C:/Program Files/Java/jre7/bin/j2pkcs11.dll
