Hi all
I am developing one application that allows me to download a file. i.e. I have one file one my server. I want to provide one link. If a user clicks on that link then he should be able to download the file.
Please help me

Not really an ORM question. I'll move this somewhere more appropriate.

What type of application are your developing? The only thing that I can infer from your question is that it is a web-based application. What technologies/frameworks are you using?

There is a sample application in our codebarn that shows how to stream files to a browser from a servlet.

It uses getResourceAsStream which depends on the file being inside the webapp's directory structure.
If your files reside outside the directory structure, you'll want to use a FileReader to read the file instead.

Also look at the Content-Disposition HTTP header. In the example the header uses the "inline" attribute. If you want the user to be presented with a "Save As" dialog box you'll want to change that to "attachment"

In any case, that code should give you a good jump start on writing this yourself.
