How to display stored image on web page?

Now that I've stored several jpg's in my
database as large objects, I'm trying to
display them on a web page using a java servlet.
Im my servlet, I've changed the content type
to image/jpeg - response.setContentType("image/jpg");
When the web page is loaded, all I see is the ID
number of the image.  How do you display the
stored image on the web page?  An example in ANY
language would be appreciated.

-Thanks
