How to connect to MS Access Database

I found this forum post specific to Mac’s on this topic:

The intro to this post showed the use of localhost in the server URL for host and port needs. I am struggling with what format should be used in the mac environment. Here is an example of what I have tried:
jdbc:ucanaccess://localhost/Volumes/Group/Database/TestDB.accdb
Is there a specific format this should be in? Do I need a port number?
