Sometimes a developer needs to provide the feature in their web application to upload file. This file can be anything like documents (PDF, doc, rtf etc.) or image (jpg, bmp, tif, gif etc.) or zip file. And after uploading the developer needs to provide another feature to download the file by clicking a link.
There can numerous ways to provide this functionality in a web application. I’m going to discuss about the database approach for doing so. In the database approach, the RDBMs should have the BLOB feature enabled to store the uploaded file as an image inside it.
This is the simplest and fastest code that shows how to implement multiple-column table sorting in JSP (Sort Ascending & Sort Descending).
