Display a database BLOB in a jsp

the IMG tag takes a src path to an image to display it. But if you are getting the image from a database (or file system) it is not part of the web app. So how would you set the src param? Or is there another way to display it, since it is a stream of bytes when you get it from the database?

The standard approach is to have the src tag of the image point at a Servlet which is part of the webapp.
eg
<img src="/myWebApp/imageServlet?imageid=42"/>

That servlet is then responsible for loading the image, and sending it out via the ServletOutputStream.
