Javazoom player not opening sfd.ser

I will warn you that I have not been programming in Java for very long, but I'm familiar with C++ and it's not so very different. Also, the program on which I'm working was not started by me, so there are areas with which I am still unfamiliar. That said, my problem...

The program, when I found it, had a "Javalayer MP3 decoder" from http://www.javazoom.net/javalayer/javalayer.html. It worked fine, but was old. Seeing that the new one had some functionality I needed, I have updated all the files I need (the music agent makefile and MusicAgent, specifically) but when I run it, I get this error:

... 8 more

The program itself is quite large, so I regret that I can't give you all the code you might need... just ask for specific bits if I'm not showing you enough.

Synthesis Filter (part of Javazoom)

static private float[] load_d()
{
try
{
Class elemType = Float.TYPE;
Object o = JavaLayerUtils.deserializeArrayResource("sfd.ser", elemType, 512);
return (float[])o;
}
catch (IOException ex)
{
throw new ExceptionInInitializerError(ex);
}
}

Java Layer Utils (part of Javazoom)

static public Object deserializeArrayResource(String name, Class elemType, int length) throws IOException
{
InputStream str = getResourceAsStream(name);
if (str==null)
throw new IOException("unable to load resource '"+name+"'");
Object obj = deserializeArray(str, elemType, length);
return obj;
}

static synchronized public InputStream getResourceAsStream(String name)
{
InputStream is = null;
if (hook!=null)
{
is = hook.getResourceAsStream(name);
}
else
{
Class cls = JavaLayerUtils.class;
is = cls.getResourceAsStream(name);
}
return is;
}

I have no idea what a hook is, but this is still the Javazoom code, so I sort of suspect that's not the problem.

MusicAgent - MusicBox

public void run()
{
if(musicSocket != null)
{
try
{
if (!initd)
{
player = new Player(sin);
initd = true;
}
player.play();
}
catch(Exception e)
{
Log.logInfo("problem with the player");
}
}
else
{
Log.logInfo("MusicBox failed to run");
}
}

Which should be innocent enough.

I've tried moving the file into multiple folders, but I suppose I can't remove that possibility entirely. So... I'm hoping someone here has seen a similar problem before, or can recognize what it might be. Thanks in advance for any tips!

The original post is quite old. But the same problem occurred to me lately: An IOException stating sfd.ser could not be read.

In my case the JVM started with a SecurityManager and the solution was to grant read access to the audio jar-Files in the policy file.

So the OP's problem could have been a permission problem.
