Ive test your code,
There's nothing wrong with your code except that the file need for your program doesn't exist... At first execution...

I've test it in a single file,
Asking for Item, category, container and location in JOptionPane mode...

Is already been linked, since you have

You can erase it...

I am using jdk 1.6.03

And there is no problem... ;-)

1.) StringTokenizer is old. Use the String.split method instead.
2.) Arrays are not the best for object oriented modelling. Create a CD class with title, category e.t.c as fields and store them in an ArrayList<CD>.
3.) Do not use a FileOutputStream for writing characters. Use BufferedWriter or PrintWriter instead.

The codes above, i mean the code that you have been posted at the top...
Save them in a file, with filename exactly the same with the public class...

Don't forget to follow what r035198x said...

Update us,
