ImageIcons read from database don't appear

Question

Hi,
I create a JavaBean to show images from filesystem and database (oracle9i) in a JTable.
The ImageIcons loaded from filesystem appear fine whith my defined DefaultTabelModel.
The ImageIcons read from database (jdbc2) with the same DefaultTabelModel appear in the correct count, but the fields or placeholders of the Images, saved as blob, are blank.
The partcode of my resultset is
BLOB myblob = null;
int bufsize = 0;
while(result.next())
myblob = ((OracleResultSet)result).getBLOB("image_container");
bufsize = myblob.getChunkSize();
byte[] buffer = new byte[bufsize];
ImageIcon icon = new ImageIcon(buffer);
Object [] row = {icon};
model1.addRow(row);
model1.fireTableDataChanged();
I don't get any errors.
Thanks
Klaus

Hi,
I changed the datatype from BLOB to 'LONG RAW' for the image in the database.
while(result.next())
byte[] bytes = result.getBytes(1);
String jd = String.valueOf(bytes);
System.out.println(jd);
//get:[B@153 [B@154
    //or [B@155 [B@156 for the 2.result
    String name = result.getString(2);
    System.out.println(name);
    //get the correct result
    FileOutputStream file = null;
    file = new FileOutputStream ("c:\\"+name+".jpg");
    file.write(bytes);
    //it works fine !!!
    ImageIcon icon = new ImageIcon(bytes);   //it is correct ?
    String ls = String.valueOf(icon.getImageLoadStatus());
    String h = String.valueOf(icon.getIconHeight());
    String w = String.valueOf(icon.getIconWidth());
    System.out.println(h+" : "+w);
    //get: -1 : -1
    System.out.println(ls);
    //get: 4
    Object [] row = {icon,name};
//icon is blank, name appears correct in jtable
//but when I need:
//ImageIcon icon = new ImageIcon(AW_Frame.class.getResource("images/emac.jpg"));
//icon and name appears correct in jtable
model1.addRow(row);
model1.fireTableDataChanged();
any ideas ?
Thanks in advance !
