I made some changes in the code of oracle.

http://docs.oracle.com/javase/tutorial/displayCode.html?code=http://docs.oracle.com/javase/tutorial/uiswing/examples/components/TabComponentsDemoProject/src/components/ButtonTabComponent.java

Giving the possibility to add an icon to the tab , plus the close tab button. Hope that helps.

public static void addTag(JTabbedPane tab, String title, Icon icon, int index){
     MouseListener close = new MouseAdapter() {

        @Override
        public void mouseClicked(MouseEvent e) {
            //your code to remove component
            //I use this way , because I use other methods of control than normal: tab.remove(int index);
        }

    };
    final ButtonClose buttonClose = new ButtonClose (title, icon, close );

    tab.setTabComponentAt(index, buttonClose);
    tab.validate();
    tab.setSelectedIndex(index);

}

public class ButtonClose extends JPanel {

public ButtonClose(final String title, Icon icon, MouseListener e) {
    JLabel ic = new JLabel(icon);
    ic.setSize(icone.getIconWidth(), icone.getIconHeight());

    JLabel text= new JLabel(title);
    text.setBorder(BorderFactory.createEmptyBorder(0, 0, 0, 5));

    ButtonTab button = new ButtonTab();
    button.addMouseListener(e);
    button.setBorder(BorderFactory.createEmptyBorder(2, 0, 0, 0));

    JPanel p = new JPanel();
    p.setSize(getWidth() - icone.getIconWidth(), 15);
    p.add(text);
    p.add(button);

    add(ic);
    add(p);
}

private class ButtonTab extends JButton {

    public ButtonTab() {
        int size = 13;
        setPreferredSize(new Dimension(size, size));
        setToolTipText("Close");

        setUI(new BasicButtonUI());

        setFocusable(false);
        setBorderPainted(false);

        addMouseListener(listener);
        setRolloverEnabled(true);
    }

    @Override
    public void updateUI() {
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2 = (Graphics2D) g.create();

        if (getModel().isPressed()) {
            g2.translate(1, 1);
        }
        g2.setStroke(new BasicStroke(2));
        g2.setColor(new Color(126, 118, 91));

        if (getModel().isRollover()) {
            g2.setColor(Color.WHITE);
        }

        int delta = 3;
        g2.drawLine(delta, delta, getWidth() - delta - 1, getHeight() - delta - 1);
        g2.drawLine(getWidth() - delta - 1, delta, delta, getHeight() - delta - 1);
        g2.dispose();
    }
}

private final MouseListener listener = new MouseAdapter() {
    @Override
    public void mouseEntered(MouseEvent e) {
        Component component = e.getComponent();
        if (component instanceof AbstractButton) {
            AbstractButton button = (AbstractButton) component;
            button.setContentAreaFilled(true);
            button.setBackground(new Color(215, 65, 35));
        }
    }

    @Override
    public void mouseExited(MouseEvent e) {
        Component component = e.getComponent();
        if (component instanceof AbstractButton) {
            AbstractButton button = (AbstractButton) component;
            button.setContentAreaFilled(false); //transparent
        }
    }
};

}
