options tag <html:select property="selectedPerson">
<html
ptions property="people"/>
</html:select>
ActionForm requires:
getSelectedPerson() / setSelectedPerson()
getPeople() - returns a collection
If the form has a value for selectedPerson, Struts will automatically prepopulate it as the selected option. That's mainly why we use the Struts tags - prepopulation.
The Action class... well that's your own business to do what you want with that selectedPerson value from the form.
That should be pretty comprehensive. I can answer other questions but to be any more specific I'm afraid I'd have to ask for your paycheck.
