You can pre-propulate the bean anytime before you attempt to build the page (on which the select boxes are on).
Use an action method, action listener, or even the beans constructor to populate the bean.
There are a few other times/ways you can pre-populate the bean, but they are more special cases.
Most people will use the beans constructor. It's the simplest and most straight forward way (plus, that's what a constructor is for... populating your Object with defaults). You can make your DB calls from within the constructor.
