One way is to send back a reference to a servlet that knows how to retrieve the image. I.e., in your .jsp, say:
<img src="/path/to/avatar/servlet?avatar=1234"/> Where 1234 is the primary key (ID) field of the avatar in the DB. Have the servlet set the response type to image/jpeg or image/png or whatever is appropriate, and then stream the bytes out of the blob from the DB.
