Stuck on Java GUI Program

[sjaycohn]

I have a problem with a Java GUI program I am writing.
I am trying to display a list of icons for a virtual (emulated) directory.
That works fine, but I want to clip the display region and use a scrollbar.
So, following some examples I found online, I create a JScrollPane and added my JPanel containing my directory JList.
The problem is, I am also showing a button and textbox in the same JFrame, and the scrollbar scrolls this too. I only want the scrollbar to scroll the JPanel with the JList.
I tried creating the JScrollPane and adding that to my JPanel, but the JList panel didn't display.

Can someone please help me figure out what I'm doing wrong?
I only want to scroll the JList panel.


I've attached my code, which compiles using the JDK 1.6
