use servlet or JSP you can set the response to send values you want.

AJAX use httpRequestXML to send request and can have a callback function to have response

you would use ajax to invoke the server and request the url. The server does its thing and sends the url back in the response. You would then use javascript to update the dom (i.e. html) on the page.

I recommend using a framework like jquery to make the ajax request and update the DOM. Plenty of examples are online.
