PKIX path building failed in Centos 7

Question

sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target; nested exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Receiving following exception while triggering the SSL certified URL. Tried to fix the error by using following command

/opt/jdk1.8.0_51/jre/bin/keytool -import –alias -genkey –keystore “/opt/jdk1.8.0_51/jre/lib/security/cacerts” -file /apps/binlistlookup/src/main/resources/binlistnet.crt
