That's a toughie.  I've done it once where I used a small popup window
(opening it with JavaScript) to go to the server, perform the query to
retrieve the information, stuff it into a JavaScript array and then return
the array to the calling page and close the window.

It works but the user will see a small window pop-up.

Other than that, it is possible to use a Java Applet to do it as well.
