If you want to draw real oriented text, try this:
import java.awt.*;
import java.awt.geom.*;
import javax.swing.*;
import javax.swing.plaf.basic.*;
public class VerticalLabelTest extends JFrame {
   public static void main(String[] args) {
      JLabel label1 = new JLabel("100,100 Label text (normal)");
      label1.setSize(200, 20);
      label1.setLocation(100, 100);
      JLabel label2 = new JLabel("100,100 Label text (rotated 90�)");
      label2.setUI(new VerticalLabelUI(true));
      label2.setSize(200, 20);
      label2.setLocation(100, 100);
      JLabel label3 = new JLabel("120,120 Label text (rotated -90�)");
      label3.setUI(new VerticalLabelUI(false));
      label3.setSize(200, 20);
      label3.setLocation(120, 120);
      JPanel pmain = new JPanel();
      pmain.setLayout(null);
      pmain.add(label1);
      pmain.add(label2);
      pmain.add(label3);
      JFrame fmain = new VerticalLabelTest();
      fmain.setSize(500, 500);
      fmain.getContentPane().add(pmain, BorderLayout.CENTER);
      fmain.setVisible(true);
class VerticalLabelUI extends BasicLabelUI {
   static {
      labelUI = new VerticalLabelUI(false);
   protected boolean clockwise;
   VerticalLabelUI( boolean clockwise ) {
      super();
      this.clockwise = clockwise;
   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);
   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) && (text == null))return;
      FontMetrics fm = g.getFontMetrics();
      paintViewInsets = c.getInsets(paintViewInsets);
      paintViewR.x = paintViewInsets.left;
      paintViewR.y = paintViewInsets.top;
      // Use inverted height & width
      paintViewR.width  = c.getWidth() - (paintViewInsets.left + paintViewInsets.right);
      paintViewR.height = 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);
      paintViewR.height = c.getWidth() - (paintViewInsets.left + paintViewInsets.right);
      paintViewR.width = c.getHeight() - (paintViewInsets.top + paintViewInsets.bottom);
      Graphics2D g2 = (Graphics2D) g;
      AffineTransform tr = g2.getTransform();
      int wh = paintViewR.width;
      if (wh < paintViewR.height) wh = paintViewR.height;
      g2.setClip(0, 0, wh, wh);
      if (clockwise) {
         g2.rotate( Math.PI / 2 );
         g2.translate( 0, - paintViewR.width );
      else {
         g2.rotate( - Math.PI / 2 );
         g2.translate( - paintViewR.height, 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, g2, clippedText, textX, textY);
         else {
            paintDisabledText(label, g2, clippedText, textX, textY);
      g2.setTransform(tr);
}Hope this helped,
Regards.
