PKIX path building failed:certificate missing

Question

I created a free Oracle DB and I'am trying to connect to it via IntelliJ Database Tools.

I keep getting this error.

[08006][17002] I/O-Fehler: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target, connect lapse 32 ms., Authentication lapse 0 ms. sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target.

Where can I get this certificate?

Please help (newbie here already spent like 2 days on this)

Answer 1

As the link to the suggestion is not working I would recommend the following solution, which works in my case:

1. Get the database certificate

You may use the following bash command for this:

openssl s_client -connect example.com:1234 -servername example.com:1234 < /dev/null | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > cert.crt

Just replace the example.com:1234 with your host and port. The database certificate will be saved as cert.crt .

2. Add the certificate to the IntelliJ database connection properties window like this:

Answer 2

I had the same problem though I was using all maven dependencies required. I tried connecting SQL Server database using Java.

This issues resolved just like that by adding the right version (Compatible for your Database server version).

I changed the mssql-jdbc version from 8.2.1.jre11 to 8.4.1.jre11 . Hope this would help somebody
