Removing border from JButton

Question

* This is a crosspost, hope you don't mind. The earlier post I made was in the wrong forum and in the wrong thread.. *
I'm trying to remove the border from a bunch of JButtons.
My code adds custom actions to a custom JToolbar. The code responsible for this looks like this:    JButton button = this.add(action);
    //button.setBorder(new EmptyBorder(1, 2, 1, 2));
    button.setBorder(null);I've tried both lines, and both work and don't work at the same time. In one panel it works but in five others it doesn't. The only difference I see between these two groups is that the panel that works uses a GroupLayout and the other panels use a BorderLayout.
Also, I'm trying to create an onMouseOver effect similar (well, exactely the same actually) as is used in Eclipse. When the users mouse hover over the button the button should be given a border, when it is not the border should be gone.
Any help on these issues would be appreciated,
Jurgen

This might also help if you want to make a button out of a Componet
