I posted this question a couple of days ago and received an answer.
Unfortunately the answer does not work for me. The problem I am having is
on the initial page of my web application I have drop-down boxes that I
want to be populated with information from a database. I have no problem
getting the recordset but do not know how to transfer that recordset data
into the drop-downs. I was able to populate the drop-downs similar to the
example used in the documentation but that does not have an example of how
to populate them with live data. Can anyone give me a quick lesson on how
to do this.

Have you discovered the collection attribute of the options tag? Your
action can build any collection you desire (ie from a database -- see
org.apache.struts.util.LabelValueBean for holding the name/value pairs).
It then places that collection into some scope (whichever you like) and
forwards to the page. Now, by specifying the key you used when placing
the collection into scope as the value to the collection attribute of
the options tag, you've got a dynamic drop-down populated from the
database.
------------- in your Action subclass
Collection c = ...;
while (...)
{
String label = ...;
String value = ...;
c.add(new LabelValueBean(label, value));
}
request.setAttribute("myCollection", c);
------------- in your JSP
<html:select ... >
<html:options collection="c" ... />
</html:select>
(This isn't in the FAQ, is it? <goes-to-check/>)
