I want to drive my combo boxes on the JSP page based on the selection user makes...meaning...if I have a combo box A and user selects a value 'X' then the other combo boxes B, C and D should pull from the database the values based on 'X' (i.e. select col2, col3, col4 from sample_table where col1='X').

Is there a simple way by which I can achieve this? Any help would be greatly appreciated.
