Display Image in another jsp

Question

hello,
I am facing a design issue of so as to how to go about displaying an image which i am retrieving from database.
I have a SubmitDoc.jsp which takes as input the doc id which i need to display looks like :
*SubmitDoc.jsp*
<FORM METHOD=POST ACTION="Retrieval">
Enter Document ID to Retrieve: <INPUT TYPE=TEXT NAME=DOCID SIZE=20/><BR>
<P><INPUT TYPE=SUBMIT></P>
</FORM>I have my Retrieval servlet which access the DB and gets the binary stream for the image data based on DOCID.
Now i try to forward result to a different jsp in order to display the binary data from the servlet.
something like this :
InputStream readImg = rs.getBinaryStream("DOCUMENT");
response.setContentType("image/jpg");
request.setAttribute("ImageData", readImg);
// response.getOutputStream().write(rb,0,len);
RequestDispatcher rd = request.getRequestDispatcher("DisplayDoc.jsp");
rd.forward( request, response );What code should i put in DisplayDoc.jsp to show the image there.
Any ideas how do i go about ?
Thanks,

What code should i put in DisplayDoc.jsp to show the image there.The same code you put in any html page to show an image:
<img src="urlToDownloadImageFrom"/>In effect you have two requests.
One for the JSP page, and then another for the image.
So often what you find is the tag on your page needs to pass the id as well
<img src="/ImageServlet?docId=abc123"/>
