Hello Ranchers

I have a simple jsp page with several input parameters. on submit of the jsp page i am using the parameters inputed by user and generating one excel file as a result and user gets the file download popup as response.

What i have done is after submit i am redirecting to a jsp page where i have wrtten a code to give the download popup to a user.

After submit i am starting some processing indicator(GIF image, i am usign java script to show some gif before form submission ) on the jsp page that some processing is going on becuase it is taking 2-3 minutes to generate file and give response.

problem here is how should i stop the procssing GIF after i get the download popup becuse i am redirecting to a jsp where code to download file is written ... what am i doing wrong??

Howdy Kishore, welcome to javaranch.

Kishore, when you post the same question somewhere else, you should Be Forthright When Cross Posting To Other Sites.

I'm not sure if I understood your problem completely. What exactly do you mean by download popup?? Also is this page where you are showing download popup the same page where the gif image is getting displayed??

If i understand well, You want to stop the GIF in your re-directed page once you are done loading the page. May be you can use label/div to show or hide your gif. if you popup is showing onload, you can write the hide gif code on page onLoad.

Hope this helps.

I have simple jsp page with text boxes as user inputs, when user hits submit button on top right corner processing gif is shown on same page.

so after submit action the response is redirect to a jsp where i have written the code to download a file. there is no page redirect for user, user gets the download file popup on the same page where he/she hit submit. but as repose is redirected to download.jsp how to stop that processing icon gif.

What browser are we taling about. We have a billion to choose from here. Are you talking about the icon in the browser chrome [aka window toolbar]? I do not think there is anything you can do about that.

Than use a setTimeout to remove it after a set period of time.

I think you need to show us some basic code on how this is all working. Right now it makes no sense.

WHy is that code in a JSP rather than a servlet. Sloppy!

You cannot get any type of notification when the file is downloaded. You'll need to change your design. Perhaps submit to a hidden iframe.
