If you have to go back to the server and read the database, just use some
JavaScript to call a function when the user makes a choice from the city
combobox. In the function, just call a servlet, have it read the places
relative to the city was selected from the database, put the list in the
request, then call the JSP page again and populate the "places" combobox
from this request parameter. We do this in some of our apps and it is
amazingly fast. Most users don't believe we even did the round-trip.

I had a similar situation.
I brought both lists into the JSP as arrays.
I then created duplicate javascript arrays on the client. Thenwhen the
user clicks the select box containg the parent item I used dhtml to dispolay
a "bound" list in the child select box. Does this make sense?
