Best Practices for GUI updating

All,

I recall some issue, at some point in my java programming career, where
subclassing a gui class (e.g. JFrame) and over-riding paint() didn't work as
intended, but over-riding paintComponent() did (or vice versa).

In order to do custom painting whenever the JRE requests it, which method should
one over-ride?

Rule of thumb: in AWT paint, in Swing paintComponent.
