Hi frns.. In my webapplication i want to add a progress bar while operation being done properly. e.g. After user clicks extract data button client system is connecting to server and fetching users data from server.This operation is taking long time. i want to add progress bar during this wait operation showing message Loading Data...... Flow is as follows: 1)User clicks Extract button 2)Req is send to jsp page which will redirect this req to servlet which will do all further operations.
