Databricks Connectivity with Thingworx 8.5

We have installed the Databricks jar file in Tomcat lib folder and restarted the tomcat, after that we created a new SQL thing with Database template and try to establish the connection by using the connection string URL and other details (Driver class name, validation string as Select 1, username and password) but still we are not able to establish the connection between Databricks and Thing Worx. Can anyone help me out this.
