How to use focusgained on a JList?

Question

Hey
I have a JList and beneath it is a JLabel. I would like the label to display the name of the item in the JList when it's clicked/selected. As I'm new to Java I guess it should be FocusGained, but I'm having trouble gettng the name from JList. Any help greatly appreciated.

You don't.  JS files can exist in three places.
1.  In the PDF file
2.  In the User Profile
3.  In the Application folders
* Note while you can execute some browser based JS to the embedded viewer in a web browser all of the API calls are non-editing.
