I have a Spring MVC project that contains a file converter. I made counting of progress in the main converter method - it displays percentage of conversion's progress in console now.

I would like to send those values to my JSP file and update my progress bar with them gradually, but I don't have any idea how to do that and because of that I can't even find any examples.

Have a look at Comet. I think you can use AJAX to get progress from server.
