Java Access Token PKCS11 Not found Provider

Hello I'm trying to access the keystore from my smartcard in Java. And I'm using the following code..

I'm using the Pkcs11 implementation of OpenSc http://www.opensc-project.org/opensc

File windows.cnf =

name=dnie
library=C:\WINDOWS\system32\opensc-pkcs11.dll


Java Code =

String configName = "windows.cnf"
String PIN = "####";
Provider p = new sun.security.pkcs11.SunPKCS11(configName);
Security.addProvider(p);
KeyStore keyStore = KeyStore.getInstance("PKCS11", "SunPKCS11-dnie"); =)(=
char[] pin = PIN.toCharArray();
keyStore.load(null, pin);


When the execution goes by the line with =)(= throws me the following exception

java.security.KeyStoreException: PKCS11 not found

at java.security.KeyStore.getInstance(KeyStore.java:635)
at ObtenerDatos.LeerDatos(ObtenerDatos.java:52)
at ObtenerDatos.obtenerNombre(ObtenerDatos.java:19)
at main.main(main.java:27)
Caused by: java.security.NoSuchAlgorithmException: no such algorithm: PKCS11 for provider SunPKCS11-dnie
at sun.security.jca.GetInstance.getService(GetInstance.java:70)
at sun.security.jca.GetInstance.getInstance(GetInstance.java:190)
at java.security.Security.getImpl(Security.java:662)
at java.security.KeyStore.getInstance(KeyStore.java:632)


I think the problem is "SunPKCS11-dnie", but I don't know to put there. I had tried with a lot of combinations...

Anyone can help me...

Answer

I am not sure the problem is the name. It looks correct. ColinD's suggestion to pass the Provider instance should rule it out as a problem.

I am guessing that the problem is with the PKCS11 support. Like, you don't have a card in your reader, or the native code cannot access the reader. Have you tried using this driver in conjunction with some "known good" software, like Firefox or Thunderbird's security modules?
