How to populate comboboxes from Database ??

[A. Lotfi]

Hi,
   
  I am using struts1.2
   
  I need to have a jsp page that has a form with two comboboxes or listboxes 
and a submit button, so the user can transfer data between the two comboboxes 
and the press submit button to update the database.
   
  is there any small example on how to get data from Database to a list box in 
a jsp page ?
   
  Thanks, your help is appreciated.
