New row adds to output on page refresh

[Kalai Selvi]

I am using jsp tag libraries to access data from the database and display using jsp.
When i open the jsp page the first time, i get correct number of records( say 1 record). When i click refresh button, i get the same row again( so now i have 2 records).

New row gets added to the output the number of times i refresh the page. Why is this happening?

Without seeing your code, we would have no way of knowing.
