How to go to previous page in JSP

I have designed a page with database in JSP,

I am having 3 textboxes on the form where user can enter ID,name and address.

Suppose user enters values such as ID="xyz" name="atm" address="ksh". Then it should prompt "Enter numerical values" and it should remain on the same page. I tried this with the "response.sendRedirect(url)" method ,Its working but the the textboxes are becoming empty.

I want such that the textboxes should not be empty ,they should contain the previously entered values.

Means I want to call "back" page or previously visited page.

It can be done using JavaScript but I want to do it in JSP.

So plzz help me
