This is not right!
You need to write a special Java Servlet that specifically extract the image
from the database using a servlet CGI parameter. Your , say Picture, Servlet
sends back to the browser the right content header type for the image
e.g "image/jpeg" or "image/gif".
Then code your JSPs to refer to the servlet in the hyperlink
<img src="<%=
request.getContextPath()+
"/servlet/PictureSevlet?pictureID="+pictureID
%>" border="0" >
You can't really do this thing from a JSP because it adds extra stuff like newlines.
It has be a proper Java Servlet unfortunately.

Subject: Displaying images
Dear all,
I have a BLOB field in a database which stored image in various formats
(JPG, GIF). When I try to write the file through the HTTP Response it always
fails. However, I successfully wrote it to a file so I assumed that my data
is valid (not corrupted). The followings is the scriptlet. Can anyone give
me a suggestion? Thanks a lot in advance.
Regards,
