Image display is better done via a servlet.
My advice in this case is to write a generic servlet for image display which
will retrieve any image from ur DB based on the parametes passed to it. All u
need do is write your normal jsp or html and call this servet whenever u need
an image to be diplayed. A sample call will look like this:
<img WIDTH=120 HEIGHT=120 src=ShowImage?urparamaters>
Alternatively, u may still achieve everything in one jsp though it is not a
good approach. Ur jsp will look like ur servlet code but u must send outpout to
ServletOutputStream and not ur usual out object. eg
javax.servlet.ServletOutputStream cout = response.getOutputStream();
I assume u know u must set response.setContentType() to the right mime type.
Hope this helps?
Cheers!
