Is there a general way to find any type of file IN a JAR ?

Question

Hi I've written an application that I want to distribute in an executable JAR format. The application runs find when I double click the Jar but ONLY when the config file is outside the Jar, however I want to distribute every thing in the Jar, because I want my program to be self contained.
I've read a lot of threads, read the Sun tutorial for JARs, but I haven't found a general way to find files within the Jar. Pehaps I should set the Class-Path in the manifest, but from what I've read in Sun Tutorial that seems that it only works for Classes.
So my question is:
Is there a general way to find any kind file ( *.txt, *.dat, *.for ) that is not a *.class, within the Jar ? Is that done on the manifest or when creating the Jar ?
The code for the app that actually works is:
            URL url = getClass().getResource( fileName );
            inputFile = new File( fileName );
            fr = new FileReader( inputFile );
            char[] dat = new char[ (int) inputFile.length() ];
            fr.read( dat );
            sDat = new String( dat );
            fr.close();
            // Parse config.txt
            System.out.print("Reading metaconfig parameters...\n");
            parseFile() ;where filename is "./config.txt".
I intend later to use a *.dat file wich will contain an object with the necessary data to configur the rest of the program instead of a *.txt file
Hope you can help me
Thank you !
