Answer 1

You should use getResourceAsStream() instead. If the file is embedded in your JAR the URI is most likely bundle:// URI

InputStream is = this.getClass().getResourceAsStream("my.conf");

Answer 2

Why do you need a file? IF you need to read the config use

Class.getResourceAsStream("/my.conf");

This will need only to be the file in the one folder with the root of your package( the same as in the root of the jar)

Answer 3

The file should be in the same package as the MyClass. I just realized you are creating a File object. Instead try using getResourceAsStream(). This is the right way if you want to read the contents from a classpath resource. Here is the example.
