Unable to connect to AMEX secure file server
Error on execution of American Express Transaction Loader Validation Program.
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Unable to connect to the American Express server. This is either because the server does not exist or the server is unreachable. Verify that the American Express server is correct. If a proxy server is needed, set up the proxy server.
How to fix it?
As per Oracle Development in the bug 20702483:
The problem is caused by the keystore $OA_JRE_TOP/lib/security/cacerts does not contain the entry for the certificate from Amex. Most of the services have the certificate related information already based on access.
