I could imagine that the big, bold font is turning some people off who might otherwise be willing to help.

DisplayTag is a JSP tag library - its output is HTML. As such, it can't handle images. You'll need to store the BLOBs as files in a publicly accessible directory, and then DisplayTag can create links to them. Or you can keep the BLOBs somewhere in memory (maybe in the application context), and then write a servlet that streams them dynamically.

Hi,

you can display it in display tag but inside display tag you have to call one servlet that is image servlet. which is basically give response as byte and display it in display coulomb.
