Hi,

Here's what i want.
I have a web page with a form, and i use a submit button to submit the data to a servlet.
While the servlet performs operation on the data, I want a gif animation to be shown to user.

I have a web page with the gif animation, so on submit i want 3 things to happen.

1. submit the data to servlet (post method)
2. open the "loading.html" page
3. once the servlet completes redirect to the results page.

Thank you

That can only happen if you employ Ajax for the POST. Otherwise, the browser will not perform any animation while the servlet is processing.

Ajax

I think this article is a good start.

Another approach -- perhaps even more complicated -- is to perform the processing in a separate thread so that the response can return immediately. The user can come back later to check on progress.

I am also trying to achieve similar goal. Can you please refer to any example or docs?

Look for the "long running process" example here.
