My code is:

         try{
                KeyStore ks =  KeyStore.getInstance("pkcs12", "SunJSSE");
                InputStream is = new FileInputStream("C:\\certificado.pfx");
                ks.load(is, "password".toCharArray()); //line ocorrus error
                String alias = ks.aliases().nextElement(); 
                Key key = ks.getKey(alias, "password".toCharArray()); 
                Certificate[] cc = ks.getCertificateChain(alias);
                X509Certificate certificate1 = (X509Certificate) cc[0];
                ret += certificate1.getNotAfter();
                ret += certificate1.getNotBefore();
         } catch (Exception e) {
                System.out.print(e.getMessage());
         }

My objective is read a certificate and get validity and an unique identifier.

@A5l-lE5 I saw the post is the same error, but is not same question. Do you agree? — fymoribe, Mar 15 '14 at 12:21
check this line no 48 from certificateTest testLoadCertificateIdeal(CertificatesTest.java:48).i think it has some errors — Divya, Mar 15 '14 at 12:30

Here is the code

KeyStore keyStore = KeyStore.getInstance("pkcs12");
        keyStore.load(newByteArrayInputStream(signature),password.toCharArray());
        Enumeration<String> enums = keyStore.aliases();
        while (enums.hasMoreElements()) {
            String alias = enums.nextElement();
            X509Certificate c = (X509Certificate)keyStore.getCertificate(alias);
            LocalDateTime expiryDate = LocalDateTime.ofInstant(Instant.ofEpochMilli(c.getNotAfter().getTime()), ZoneId.systemDefault());
        }
