Because the dependent dropdown needs to change when the selection in the other one changes, you'll need to implement an onChange handler. You have several options for this, one without AJAX. In any event, browsers will need to have Javascript enabled due to the onCHange handler. The simplest option is to submit the form and redisplay it. You'll need to put the dropdowns outside of any overwritten values (domain objects come to mind) to ensure that th form input it redisplayed. The dependent dropdown will then be filled with the correct values. The other option is to use AJAX. When the State dropdown changes, you'll fire a special event. You can choose here if you want to have the ActionBean return a list of values (with which you replace the current options), or a JSP fragment with the new control. I'd choose the latter, because you can most easily have different labels & values, and because you can group and/or disable items.
