jsp scriplets will only execute once, you cannot embed them into a javascript chunk of code. the jsp scriptlets are compiled and run on the server, javascript runs on the clients browser.
you will need to do all of this in javascript or when the user submits the page have it submit to an action that can add another row of inputs and then return back to the page.
this could be tough for you if you are just a beginner.
