Accessing a file in a runnable JAR

Question

I have a program that needs to use a .txt file in it. I have used the following code successfully to run the program right from eclipse:

File configFile = new File("src/config.txt");

With the file obviuosly residing in the src folder. When I export to a JAR file though it can't find it. I know that you have to get the file as a resource, and I've done this before with images, but I can't get it to work with a file. I tried this, but it didn't work:

URL fileURL = this.getClass().getResource("config.txt");
File configFile = new File(fileURL);

But it won't compile, as it doesn't like the `newFile(fileURL)' portion. I've checked this out online, and found a bunch of stuff, but it all seems to relate to reading the file, and not simply adding it to the JAR. Can anybody help me out with this? Thanks.

Why would you add a file to a jar, if you don't want to read it? — Bálint, Apr 10 '16 at 01:13
asked and answered many times -- there are no "files" inside of a jar file. Use it as a resource. — Hovercraft Full Of Eels, Apr 10 '16 at 01:13

I need to use the file for the FileReader class, so it needs to be a file. — user3226170, Apr 10 '16 at 01:24
I know `InputStream in = this.getClass().getClassLoader() .getResourceAsStream("configFile.txt");` will work, but again, it won't be a `File`, which I need it to be to work. — user3226170, Apr 10 '16 at 01:29
