Java nssdb connection: Could not initialize NSS

Question

I'm trying to pull certificate data from an nss db using Java. Here is my code:

try {
        char[] password = new char[0];
        Provider nss = new sun.security.pkcs11.SunPKCS11("C:\\ntdps_temp\\proj\\NSSdb\\scripts\\pkcs11.cfg");
        Security.addProvider(nss);
        KeyStore ks = KeyStore.getInstance("PKCS11", nss);
        ks.load(null, password);
        for (Enumeration<String> aliases = ks.aliases(); aliases.hasMoreElements();) {
            System.out.println(aliases.nextElement());
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Here is pkcs11.cfg:

name = NSSdb
nssModule = keystore
nssDbMode = readWrite
nssLibraryDirectory = C:\ntdps_temp\proj\NSSdb\lib
nssSecmodDirectory = C:\ntdps_temp\proj\NSSdb

Here is my stack trace:

Note line 30 refers to line Provider nss = new sun.security.pkcs11.SunPKCS11("C:\\ntdps_temp\\proj\\NSSdb\\scripts\\pkcs11.cfg"); here

I am running 32 bit Java for this particular program. Thanks in advance for any help

I will take a random shots here. is the config file exists? does it accessible by java program? — kucing_terbang, May 22 '18 at 15:12
Yes and yes. If I make it an invalid file, I get a different error that says it is an invalid configuration file — sufah1, May 22 '18 at 15:23
hmmm okay. Then, could you try to read the config file. And then, pass it into the constructor via `new ByteArrayInputStream(yourcfg.getBytes())` — kucing_terbang, May 22 '18 at 15:32
I am reading the config file, SUNPKCS11 takes it as a constructor already. — sufah1, May 22 '18 at 15:40
