I am trying to create an ImageIcon
using a byte[] that I got
from the result set using getBytes.
The DB I am using is Access 2000
and I store my image as OLE Object data type.
I use
byte[] tmpValue = rs.getBytes(columnInt);
ImageIcon tmpImage = new ImageIcon(tmpValue);
..then When i print the imageIcon height
I get -1 and when I print the
imageIcon.getImageLoadStatus();
it returns "4" -- equivalent to an error loading
Any suggestions???

If you are trying to write both bits at he same time (ie read from db and convert into ImageIcon), do them one at a time first.
Probably read the byte stream and dump it to either standard out or a file. If you dump it to a file you should be able to load it in a viewer.
After you know this is working, debug the ImageIcon bit. I've had problems with ImageIcon before when trying to do two things at one with it.
 
It is sorta covered in the JavaRanch Style Guide.
