Java – JSP progress bar

Is there a simple way to implement the progress bar in JSP Basically, I have a JSP page to go to the servlet that calls the method. Now this process will run for a long time. I want to indicate the status of the progress, just like the progress bar displayed in the eclipse taskbar when we execute any Java program

I found a good tutorial here http://onjava.com/pub/a/onjava/2003/06/11/jsp_progressbars.html But it rarely seems out of date

Is there a new simple way to do this?

Solution

Once you get into the details, determining the progress of a specific task is very complex For example, how do you determine that you have completed 50%? What happens if the last 10% of the tasks account for 1 / 2 of the total time?

In general, for web applications, if you really need a progress bar, it's best to use the Ajax path, like some posters mentioned above However, I find it appropriate to show users what is happening on the Internet Just make some spinner visible when the page is submitted, and then hide it again when rendering (see here) This is easy to do, does not result in additional performance loss, and indicates some progress
