I have no idea what you are asking.

But, if you are asking if you can convert that JavaScript code to JSP code, then no, you cannot. The JavaScript code runs after the user has filled in values into the form. Any JSP code runs before the page is even sent to the browser, so there is no way that JSP code can access form values from a form that the user hasn't even seen yet.

Please read this article to understand how JSP works.
