Hi,

Am new to the environment. Am trying to connect to MSSQL database. I've installed the jdbc in the appropriate directory but i get the error below when previewing the data source "com/microsoft/sqlserver/jdbc/SQLServerDriver has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0"

Environment Knowage 7.1, Windows 10

Hello,

I think there is a mismatch between the java version and the driver version.
