Hi everybody. I have a question to ask your. I am now doing a web application for a company, it is count the variable in the period of time. But this may take a while depends on the period of time let say one month, it may take a long time to do it. So i came out with the ideal to use a progress bar to tell user what percentage is it. But there is a problem which i don't know how it is possible to communicate from the Servlet to the JSP page that what is the progress. So just to ask is it possible to have a progress bar for this kind of process, i have gone to search on Google and is for file upload. I want it for normal Servlet like database query or counting and calculation. Will it be possible to post some sample full code? Hope i can receive your reply, thanks for reading.
