That's completely up to you, and what makes sense for the structure of your project.
Personally, I like to have a separate source folder for application settings (maybe something like etc/main/). Then, within that folder, I use the package that is closest to the class that's primarily using the settings. Let's say that your data access resides in the package com.example.myapp.db, then I would put the properties file in etc/main/com/example/myapp/db.
