Referencing files inside a JAR
===

I am creating a Java app for some serial port communication and within the app's folder I have two resources that need to be present at run-time. The first is an image that is being used as a splash screen and the other is a configuration file that needs to be read as the program starts.

Here is an abridged version of the output from the "tree" command in Linux, the two files that I need to be referencing are "commandSet.config" and "splash-screen2.png"

    .
    ├── bin
    │   ├──...
    ├── commandSet.config
    ├── app-manifest.txt
    ├── splash-screen2.png
    └── src
        ├── events
        │   └── InterfaceEvents.java
        ├── models
        │   ├── Command.java
        │   └── Phone.java
        ├── operations
        │   ├── Application.java
        │   ├── ...
        └── views
            ├── CallDialog.java
            ├── SplashScreen.java
            └── Window.java

I am currently referencing in the following lines:

    BufferedReader in = new BufferedReader(new FileReader("commandSet.config"));

and

    JLabel image = new JLabel(new ImageIcon("splash-screen2.png"));

This works fine when I am running it from Eclipse, but as soon as I export to a runnable JAR the files are not moved and therefore aren't correctly referenced. I have tried moving them into the "src" folder, which resulted in them being archived within the JAR, but I still couldn't reference them. 

I'm pretty new to the concept of exporting Java projects, so maybe I have missed something obvious. If someone could show me the best way to do this and the best approach for future project file systems, I would be very grateful. Cheers!
