    // com.ack.j2se.io.LoadResourcesAsStreamFromClass.class

    // subdirectory of the directory that holds LoadResourcesAsStreamFromClass.class
    InputStream fileStream = resourceClass.getResourceAsStream( "resources/fox.txt" );

    // once you have a handle on the input stream, use to populate properties
    Properties props = new Properties();

    // this is a very good way of storing and accessing java resources
    // that are stored within a jar file
