you should create a simple List Cell Renderer and call it in your listName.setCellRenderer(new YourListCellRenderer());

Eg:- Your List Cell Renderer Code should something like this

public class MyListCellRender extends DefaultListCellRenderer {

        @Override
        public Component getListCellRendererComponent(JList list1, Object obj, int index, boolean isSelected, boolean isFocus) {
            super.getListCellRendererComponent(list1, obj, index, isSelected, isFocus);
            setForeground(Color.WHITE);
            setOpaque(isSelected);
            return this;
        }

}

then in call it in what or wherever you want like form active event or initial stage in my case I callit in initial Stage which after form create.It mean after initComponent();

    initComponents();
    jList1.setUI(new WebListUI());
    scrollBar.setOpaque(false);
    scrollBar.getViewport().setOpaque(false);
    jList1.setOpaque(false);
    jList1.setCellRenderer(new TransparentListCellRender()); 

This is my Sample
