The following error appears:
2018-06-19 01:24:18,924 ERROR {vic:9864} [/propertyDefinitions] [ResourceExceptionMapper] Internal Server Error (500): Internal Server Error
! javax.ws.rs.ProcessingException: 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
The SSL certificate used to secure VIC is trusted by the operating system but not by the VIC Java Runtime Environment. This means that while the administration webpage can load securely (the browser shows a secure icon in the address bar), the page's underlying calls to the VIC service are rejected because of the untrusted certificate.
The solution is to perform steps 4 and 5 from the "Configuring the Veritas Information Classifier for secure client connections" section of the Enterprise Vault™ Classification using the Veritas Information Classifier guide.
If you are using the self-signed certificate created by EV 12.3 and later, you must first export this certificate to a base-64 encoded X.509 (.CER) file using the Certificates MMC snap-in, so that you can use that file in the aforementioned steps.
Note: You will need to reimport the certificate to the JRE keystore each time you upgrade EV.
