How to make a JPanel transparent? Not able to do it with setOpaque(false)

Question

Hi all,
I am writing a code to play a video and then draw some lines on the video. For that first I am playing the video on a visual component and I am trying to overlap a JPanel for drawing the lines. I am able to overlap the JPanel but I am not able to make it transparent. So I am able to draw lines but not able to see the video. So, I want to make the JPanel transparent so that I can see the video also... I am posting my code below

Add your video component to one layer and your non-opaque panel to another layer.Did you try that with JMF? It does not work for me. As I said, the movie seems to draw itself always on top!
