But now I have the problem with the certificate issue. Although it should be possible to connect without verification (-> false), I get the following error message:
Could not connect to address=(host=XX.inpro.de)(port=3306)(type=master) : Could not connect to XX.inpro.de:3306 : sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Do I have to set another JDBC parameter?
Or the other way around: if I will set verification to true, how can I set the path to the “.cert” file?
thank you for your nice video how to import certificates in KNIME Application Plattform. Now I can connect to MariaDB in the enterprise net! Great!
In addition to the video I had to copy the cacert file from …jre/lib/security to …jre/bin and then call the keytool. After it I had to copy the enhanced cacert file back.
