sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Description

I use mac and java to send get request to geocode.arcgis.com and getting following problem:

    sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Solution

Download the certificate first:

openssl s_client -showcerts -connect geocode.arcgis.com:443 </dev/null 2>/dev/null|openssl x509 -outform PEM >mycertfile.pem

Then import the certificate using root:

keytool -import -alias example -keystore  $(/usr/libexec/java_home)/lib/security/cacerts -file ~/Downloads/InstallCert-master/mycertfile.pem
