[SOLVED] PKIX path validation failed: java.security.cert.CertPathValidatorException: Path does not chain with any of the trust anchors

PROBLEM

PKIX path validation failed: java.security.cert.CertPathValidatorException: Path does not chain with any of the trust anchors

CAUSE 

does not recognize the digital certificate  issuer or path validatioan failed

My CODE 

  PKIXParameters params = new PKIXParameters(Collections.singleton(anchor));
  params.setRevocationEnabled(true);

SOLVED

• Change the digital certificate issuer/certificate authority to JKS format
• Change the source code to

 KeyStore keystore = KeyStore.getInstance("JKS");

            try (InputStream is = Files.newInputStream(Paths.get("root.jks"))) {
                keystore.load(is, "".toCharArray());
            }

            PKIXParameters params = new PKIXParameters(keystore);
            params.setRevocationEnabled(true);
