I haven't put any of this into tags but....
My experience is limited to our Oracle system.
I created two classes:
One wraps the Oracle implementation code and avoids the need to
import oracle.sql.BLOB;
import oracle.jdbc.OracleResultSet;
in places that are isolated from driver implementation details
Another converts the BLOB's to and from Image and byte[] so I can
display them.
For the web side, I adapted a servlet to display the image using this
fragment:
byte[] imageData = image.getImageBytes();
if ( imageData != null && imageData.length > 0){
response.setContentType("image/jpeg");
ServletOutputStream sos =
response.getOutputStream();
sos.write(imageData);
}
I only save a thumbnail in the database as a BLOB so the thumbnail is
the only image being returned in the response stream.
