Smooth Animation

It sounds like your problem is not in the painting but in your choice of sprites/frames. If you can post an example of what is giving you this "jerky" motion, we might be able to help. What you're probably looking for, however, is a way to interpolate intermediate frames and paint those so that transitions are "smoother." The best way to accomplish that task depends greatly on the subject matter.

that isn't particularly useful due to the poor timer resolution of currentTimeMillis().

you'd do better just polling currentTimeMillis() in a tight loop

one thing i'd definately try is instead of calling repaint(), and then overiding paint is creating a method something like:

updateSprites(){

Graphics g = getGraphics();

//then paint on g

}

then call updateSprites instead of repaint(). This tends to run smoother, i think because calls to repaint() sometimes become cued, so a few paint(Graphics g) calls might end up getting missed.

hope this helps, it did for me when i was doing some Java game coding earlier in the year..
