dynamic selector list

[mcraven.2]

I'm creating a web form that has two selectors. You make a selection
in the first selector and a specific list is to show up in the second
selector based on a database query. The first selector is also filled
in by a database query. Can someone provide me with some guidance on
how to do this? I'm thinking I want to use the onchange event of the
first selector but I don't know how. What would I call with the
onchange event? Would I refresh the form or call a servlet that would
fill in the second selector? For reference, I'm using JSP.

Google "AJAX", but provide a non-Javascript alternative.

Go find yourself an AJAX tutorial - the "Ajax in Action" book perhaps
for starters.

I've been sucking all the data out of the database and storing it in
the page. You can see an example of an early stage version at
http://dorward.me.uk/tmp/select.html . This is unfinished so will need
some work, but you might find it useful as a starting point. (The
script is almost finished, but isn't live anywhere at present and I
can't put the alpha online for various reasons).
