Images are blank in JTable

I'm trying to add an image to a column in a JTable but they appear blank when the columns are filled.

I am overriding the getColumnClass. Here is the table declaration...

   laneTable.setModel(new javax.swing.table.DefaultTableModel(
        new Object [][] {
            {null, null, null, null, null, null},
            {null, null, null, null, null, null},
            {null, null, null, null, null, null},
            {null, null, null, null, null, null}
        },
        new String [] {
            "Lane ID", "Status", "Traffic", "Gate Arm", "Lane Indicator", "Temperature"
        }
    ) {
        Class[] types = new Class [] {
            java.lang.String.class, java.lang.Object.class, java.lang.Object.class, java.lang.Object.class, java.lang.Object.class, java.lang.Object.class
        };

        @Override
        public Class getColumnClass(int column)
        {

            if (column == 4)
            {

                return ImageIcon.class;
            }
            return Object.class;
            // other code; default to Object.class
        }


    });

so obviously, column 4 is my column where images are to be displayed. I am populating my table with..

for(int i = 0; i < 200; i++){
  ImageIcon icon = new ImageIcon("Images/test.jpg");
  laneTable.getModel().setValueAt(icon,i,4);
}

The path to my images is /src/Images/test.jpg in case my pathname is somehow incorrect... Ive been dealing with this for the last week and i CANNOT figure out why these images keep showing up blank in my table.

Ideas?

edit here is what I guess is an SSCCE. No idea if it will work or not..

edit Tested the images in a new label, the images show correctly inside a label, but are still blank inside of the table.

A blank image might not be a path issue but a rendering issue. Look at your CellRenderer for that column. Is it using the default renderer or are you doing something special.

Try just printing out the path to make sure it is getting in the cell. Also try accessing that path from outside the JTable to make sure there is not a path issue at all.
