javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed

ERROR:

unable to find valid certification path to requested target

Many times I face this error and has resolved by Importing the Certificate to JRE lib.

But today i face a strange issue even after Importing the certificates not able to proceed testing further.

Another way to resolve the issue:

Go to directory:(

D:\Oracle\Middleware\user_projects\domains\WEBCENTER_domain\bin

Edit the file

setDomainEnv.cmd (Windows)   or   (setDomainEnv.sh   for Linux) and delete the the lines

-Djavax.net.ssl.trustStore=${WL_HOME}/server/lib/DemoTrust.jks

ENJOY!!!!!!
