combo boxes and iterator

[alex pandiyan]

Hi,
I have 3 combo boxes in jsp page.
If user selects 3 diff values in combo and clicks
submit button,i have to display values.
Scenario;
combo box:1 country
combo box:2 state
combo box:3 city
If user selects "state1" in 2nd combo,"all cities" in 3rd combo,
i have to display in such a way that cities in state1-1 column and cities not in state1 in another column on the same jsp.
Am having the values of combo boxes in 3 arraylists.
How to query them and display results?
Will using an iterator would be effective?
Any validation sample code would be useful.
Thanks in advance.
