something like this:

public class JPatternPanel extends JPanel {

   Image pattern;

   public void paintComponent(Graphics g) {
       super.paintComponent(g);
       Insets insets = getInsets();
       Dimension size = getSize();
       if(patterm != null) {
           int width = pattern.getWidth(null);
           int height = pattern.getHeight(null);
           if(width > 0 && height > 0) {
               for(int i = insets.left; i < size.width - (insets.left +
insets.right); i += width) {
                   for(int j = insets.top; i < size.height - (insets.top +
insets.bottom); j += height) {
                       g.drawImage(pattern, i, j, null);
                   }
           }
   }
   //paint here whatever you need
}
