How to use File download using CommonsFile API

I have used CommonsFile to upload a file to my server and write the BLOB into the database. When i retrieve the Blob from the database how can i provide it for the user to download as file. Should i write it to a File before i send it to the client. or can i send the Input/Output stream directly to the client by setting the appropriate response type? I am not able to get wat to do. Help me on this regard

Regards

I don't see the point in writing to file on the webserver.
I would try streaming it right to the browser.
