At a guess, you could have a servlet that grabs the image from the database,
and outputs it to the output stream. So your IMG code in the HTML doc would
look something like:
<img src="/servlet/ImageServlet?id=1"
alt="/servlet/ImageServlet?id=1&comment=true" />
The servlet could grab the blob from the database and write it out.

Subject: Displaying Generated Image on Jsp
Hi,
We have web J2EE web based application which is deployed on weblogic
8.1(on Unix) as an ear.
This EAR contains some EJB's some jar files and a war file.
Now we want to display an image on the jsp after retreiving it from
the database.Image is stored in the database as a BLOB object.
Currently what is implemented is e.g as soon as user selects a
product an image file (.jpg) is generated from the BLOB
object (at some predefined location say C:\ImageFolder) and in
jsp(HTML) we display this image with with giving this path in
IMG src tag.
Is there any way where we can get rid of this absolute path(hard
coded) path and generate the image at a relative path and display
from there in our jsp or is there any other wat to achieve it.
Thanks
Govind
