Animated .gif in JTable cell

Question

Hi -
I have an actual animated .gif that I would like to display in a JTable's cell. By 'actual animated .gif', I mean that it is one file that is animated, and not a succession of files that I would loop through to look like animation.
I have edited the following code that I found in a previous post. My .gif does display in the JTable and animates only ONCE. Once it animates once, it stops. How can I cause it to keep looping through and repeating the animation?
Thanks!

Code below:
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import javax.swing.*;
import javax.swing.table.*;
public class AnimatedIconTableExample extends JFrame
public AnimatedIconTableExample()
super("AnimatedIconTable Example");
final Object[][] data = new Object[][]
{ new ImageIcon("images/Upload.gif") }
final Object[] column = new Object[]
{ "Image Uploading" };
AbstractTableModel model = new AbstractTableModel()
public int getColumnCount()
return column.length;
public int getRowCount()
return data.length;
public String getColumnName(int col)
return (String) column[col];
public Object getValueAt(int row, int col)
return data[row][col];
public Class getColumnClass(int col)
return ImageIcon.class;
JTable table = new JTable(model);
table.setRowHeight(50);
setImageObserver(table);
JScrollPane pane = new JScrollPane(table);
getContentPane().add(pane);
private void setImageObserver(JTable table)
TableModel model = table.getModel();
int colCount = model.getColumnCount();
int rowCount = model.getRowCount();
for (int col = 0; col < colCount; col++)
if (ImageIcon.class == model.getColumnClass(col))
for (int row = 0; row < rowCount; row++)
ImageIcon icon = (ImageIcon) model.getValueAt(row, col);
if (icon != null)
icon.setImageObserver(new CellImageObserver(table, row,
col));
class CellImageObserver implements ImageObserver
JTable table;
int row;
int col;
CellImageObserver(JTable table, int row, int col)
this.table = table;
this.row = row;
this.col = col;
public boolean imageUpdate(Image img, int flags, int x, int y, int w,
int h)
if ((flags & (FRAMEBITS | ALLBITS)) != 0)
Rectangle rect = table.getCellRect(row, col, false);
table.repaint(rect);
return (flags & (ALLBITS | ABORT)) == 0;
public static void main(String[] args)
AnimatedIconTableExample frame = new AnimatedIconTableExample();
frame.addWindowListener(new WindowAdapter()
public void windowClosing(WindowEvent e)
System.exit(0);
frame.setSize(300, 150);
frame.setVisible(true);

I've heard of that problem before... I think it has something to do with how the image is loaded. I found an example of how Sun does animated gifs here: http://java.sun.com/products/java-media/2D/samples/suite/Image/DukeAnim.java
I hope it helps.
