Hello:
I am trying to connect to cassandra database using ReadyAPI but am not able to connect.

I am getting the following error message when trying to connect:

ERROR: Failed to register the JDBC driver [com.dbschema.CassandraJdbcDriver].
ERROR: java.lang.ClassNotFoundException: com.dbschema.CassandraJdbcDriver

this is the connection string i am using

jdbc:cassandra://<IP>:<HOST>/<DATABASE>?user=<USER_NAME>

how do i proceed?

any help is appreciated
