Error sql connection

Question

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 (unable to load class [com.microsoft.sqlserver.jdbc.SQLServerDriver])

I could not connet in sql server.

Hi,

did you test the connection to the datasource? You can do so by going to the Data Source section and clicking on the TEST button.

Good Morning.
When you click test nothing happens.
