    public Sequence getSequence(String filename)
        try
            return getSequence( new FileInputStream(filename));
        catch (IOException ex)
            ex.printStackTrace();
            return null;
     * Loads a sequence from an input stream. Returns null if

    public Sequence getSequence(InputStream is)
        try

                is = new BufferedInputStream(is);
            Sequence s = MidiSystem.getSequence(is);
            is.close();
            return s;

Answer 1

new FileInputStream(filename))That only works for files. Resources in JARs are not files. You should always (when possible) use getClass().getResourceAsStream() to open streams on resources, loading them from the classpath -- regardless of whether your app is a bunch of loose files or in a JAR.
