I have one jsp form that it has upload file input. The file is being uploaded to the servlet and servlet is reading the file successfully. The servlet is processing the data of file doing some stuff after reading the file. for me I can't assume how much time the servlet is going to take because as I told servlet is processing data of the file so it might be big data with other files and will take longer time. what I need is I want to show to user such progress bar that indicates to him the server is busy processing the uploaded file.  how is that ? anyone can help me please.

That progress bar would have to be displayed by the browser; you'd want to display something which blocks the user from clicking on the HTML displayed in the browser until it receives a response.

Of course you'd have to do that in JavaScript so I'll move this thread to the JavaScript forum for you.

I remember doing this several years ago -- one necessary condition is that your request has to be sent via AJAX, otherwise it's not your code which is waiting for the response. I can't remember in detail how I did it but googling javascript progress bar might well lead you to solutions.
