@Zhedar the link which is said there has been expired and neither of answers work — Soheil, Feb 08 '13 at 17:22
the 2nd answer (not accepted) gives another short explanation about the paint-approach. — Zhedar, Feb 08 '13 at 17:23

You could use the class VerticalLabelUI created by a dev: ~~http://tech.chitgoks.com/2009/11/13/rotate-jlabel-vertically/~~ (dead link now thanks MadMike for the archive link)

JLabel jl = new JLabel("TEST");
jl.setUI(new VerticalLabelUI(true));

The VerticalLabelUI class

public class VerticalLabelUI extends BasicLabelUI {

    static {
        labelUI = new VerticalLabelUI(false);
    }

    protected boolean clockwise;

    public VerticalLabelUI(boolean clockwise) {
        super();
        this.clockwise = clockwise;
    }

    @Override
    public Dimension getPreferredSize(JComponent c) {
        Dimension dim = super.getPreferredSize(c);
        return new Dimension( dim.height, dim.width );
    }

    private static Rectangle paintIconR = new Rectangle();
    private static Rectangle paintTextR = new Rectangle();
    private static Rectangle paintViewR = new Rectangle();
    private static Insets paintViewInsets = new Insets(0, 0, 0, 0);

    @Override
    public void paint(Graphics g, JComponent c) {
        JLabel label = (JLabel)c;
        String text = label.getText();
        Icon icon = (label.isEnabled()) ? label.getIcon() : label.getDisabledIcon();

        if ((icon == null) &amp;&amp; (text == null)) {
            return;
        }

        FontMetrics fm = g.getFontMetrics();
        paintViewInsets = c.getInsets(paintViewInsets);

        paintViewR.x = paintViewInsets.left;
        paintViewR.y = paintViewInsets.top;

        // Use inverted height &amp; width
        paintViewR.height = c.getWidth() - (paintViewInsets.left + paintViewInsets.right);
        paintViewR.width = c.getHeight() - (paintViewInsets.top + paintViewInsets.bottom);

        paintIconR.x = paintIconR.y = paintIconR.width = paintIconR.height = 0;
        paintTextR.x = paintTextR.y = paintTextR.width = paintTextR.height = 0;

        String clippedText = layoutCL(label, fm, text, icon, paintViewR, paintIconR, paintTextR);

        Graphics2D g2 = (Graphics2D) g;
        AffineTransform tr = g2.getTransform();
        if (clockwise) {
            g2.rotate( Math.PI / 2 );
            g2.translate( 0, - c.getWidth() );
        } else {
            g2.rotate( - Math.PI / 2 );
            g2.translate( - c.getHeight(), 0 );
        }

        if (icon != null) {
            icon.paintIcon(c, g, paintIconR.x, paintIconR.y);
        }

        if (text != null) {
            int textX = paintTextR.x;
            int textY = paintTextR.y + fm.getAscent();

            if (label.isEnabled()) {
                paintEnabledText(label, g, clippedText, textX, textY);
            } else {
                paintDisabledText(label, g, clippedText, textX, textY);
            }
        }
    g2.setTransform( tr );
    }

}

You can create a method that will transform your text into an HTML code like this:

public static String transformStringToHtml(String strToTransform) {
    String ans = "<html>";
    String br = "<br>";
    String[] lettersArr = strToTransform.split("");
    for (String letter : lettersArr) {
        ans += letter + br;
    }
    ans += "</html>";
    return ans;
}

Afterwards, if you'll use this method in a setText method like this: someLabel.setText(transformStringToHtml(someString)); where someString = "Test" you will receive:

T
e
s
t

in your label.

@AlexWien Care to explain why? – Michael Feb 08 '13 at 17:57
I have not downvoted, but: the OP aksed for a rotated text, not for letters unrotation below each other. – AlexWien Feb 08 '13 at 18:00
@AlexWien I didn't accuse you for down voting. But you are right, the answer that was accepted answers the question correctly. Other than that, this solution is pretty quick and not complicated. – Michael Feb 08 '13 at 18:06
I event don't like the accepted answer, I would have done it with a custom view and an transformation matrix. Probaly this exaclty is what the external lib makes, but I avoid external libs if they havent a big benefit. – AlexWien Feb 08 '13 at 18:09
@AlexWien so why don't you share us your idea to solve this problem ? – Soheil Feb 08 '13 at 18:30
