Doubt in swing-dragging

Question

How to a drag a component build in to the container. Suppose if I constructed a button within the panel it should be moved along with the mouse dragged event and on mouse released it should be placed in that area.In short how should I drag and drop the component?
Thanks in advance

Try this:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.text.*;
public class TestTextArea extends JFrame
     JScrollPane scrollPane;
     JTextArea textArea;
     ImageIcon image;
     public TestTextArea()
          JPanel panel = new JPanel();
          setContentPane( panel );
          panel.setLayout( new BorderLayout() );
          image = new ImageIcon("????.jpg");
          textArea = new JTextArea( "one two", 10, 30 )
               public void paintComponent(Graphics g)
                    Point p = scrollPane.getViewport().getViewPosition();
                    g.drawImage(image.getImage(), p.x, p.y, null);
                    super.paintComponent(g);
          textArea.setOpaque(false);
          textArea.setFont( new Font("monospaced", Font.PLAIN, 12) );
          scrollPane = new JScrollPane( textArea );
          panel.add( scrollPane );
     public static void main(String[] args)
          TestTextArea frame = new TestTextArea();
          frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
          frame.pack();
          frame.setVisible(true);
}
