If you cannot or do not want to use Ajax then the only other way that I know to do this is with JavaScript. An Internet search will surely turn up several examples. A JavaScript solution works fine as long as your total list of values is fairly small. A previous project of mine used JavaScript for smaller lists and page refreshes for larger lists. I think the cutoff for "larger" was around 1000 expected items.
Edit: I see Merrill posted while I was typing my response. I will add this...part that can be confusing about the JavaScript approach for dynamic data is that you will be using
Java code or tags in your
JSP code to create the JavaScript code. For some reason I always get confused when I have to mix the two together.
