Ron, look at the javadocs on JTree, DefaultTreeCellRenderer and other related.  
Also look at the topic in general: 
http://java.sun.com/docs/books/tutorial/uiswing/components/tree.html

    I've been able to completely replace the folder images and use my own 
custom images thar are more appropiate for the data I'm displaying with the 
Tree. What you want to do is replace the plain folder image with one that has a 
plus next to it. You can go beyond this using different icons for whatever 
criteria you may define. (This may be overkill for your application)

Also take a look at this short tip: 
http://www.developer.com/java/other/article.php/768051

One final note, I recall reading somewhere that Microsoft own some sort of 
patent on use of plus/minus images for this file-browsing context. Maybe others 
on the list can verify whether this is true or just a hoax/urban legend.
