When specifying a config profile file you may use globally accessible URLs or file names provided with --files options (docs). Here is an example with --files:

Contact points should be provided as host:port pairs (docs), here is a sample application.conf:

Note the datacenter property which is mandatory when explicitly specifying contact-points. Daemon property ensures that cached sessions won’t stop your app from exiting.

Unless you’re doing some serious reconfiguration in application.conf then it’s recommended to use standard SCC properties (docs).

Thank you! It worked for me.

But I still cannot use a Java Driver profile:

 

It seems to ignore the contact-points configured under this profile (and probably everything else). I must be doing something wrong and this could be the wrong channel to ask for help, so could you point me where can I get help with this?

Thank you, again!
