Subject RE: Commons fileUpload: write to disk permission problem
Date Mon, 26 Jun 2006 11:04:32 GMT
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.
