You can use a Servlet to send the image data as a binary stream to the
client and in the JSP place an image tag linking to that servlet.
Data telling the servlet what image data to retrieve can be sent along as
request parameters or placed in the Http Session.

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.
