Try the below code to get the keystore from usb token using java

class Test {
    public static void main(String args[]) throws IOException, GeneralSecurityException, DocumentException, CertificateVerificationException{
        
        // Create instance of SunPKCS11 provider
        String pkcs11Config = "name=eToken\nlibrary=C:\\Windows\\System32\\eps2003csp11.dll";
        java.io.ByteArrayInputStream pkcs11ConfigStream = new java.io.ByteArrayInputStream(pkcs11Config.getBytes());
        sun.security.pkcs11.SunPKCS11 providerPKCS11 = new sun.security.pkcs11.SunPKCS11(pkcs11ConfigStream);
        java.security.Security.addProvider(providerPKCS11);

        // Get provider KeyStore and login with PIN
        String pin = "12345678";
        java.security.KeyStore keyStore = java.security.KeyStore.getInstance("PKCS11", providerPKCS11);
        keyStore.load(null, pin.toCharArray());

        // Enumerate items (certificates and private keys) in th KeyStore
        java.util.Enumeration aliases = keyStore.aliases();
        String alias = null;
        while (aliases.hasMoreElements()) {
            alias = aliases.nextElement();
            System.out.println(alias);
        }
    }
}
