Because swing is a desktop programming framework. It is not used in web
applications. It is not used in Wicket applications. It only knows how to
open windows using the computer's windowing system - the computer that it is
on. It does not know how to generate HTML or know anything about HTTP.
If you want a confirm dialog in a web app, you need to use javascript.
<script>confirm('Are you really sure that you are programming a web
app?');</script> This will open on the client computer.
