There's a couple of different ways, like checking if a page is missing:

     <wiki:NoSuchPage page="PageName">
       <p>Missing page!</p>
     </wiki:NoSuchPage>

and checking if the page exists:

     <wiki:PageExists page="PageName">
       <p>Page exists!</p>
     </wiki:PageExists>

There's probably a few more but that will likely do the trick.

You can find examples in the JSPs delivered with JSPWiki. There
are lots of them.
