Downloading a binary file from DB

I want to download a binary file from the DB and prompt the user to save or open it i.e the "File download" dialog box that shows up when we try to download a file in many websites.

I understand that is done by the browser but may be wrong. So can you please tell me once I get the Inputstream from the DB using JDBC where should I write it so that it shows up the "File download" dialog box in a browser.

Welcome to the JavaRanch.
Are you writing a servlet and want to prompt a user to save a file? If so, have a look at this article.
If not, you'll have to be more specific.
