There are at least two options; using the <s:select...> tag or building the
options manually.
If you're using the <s:select...> tag, assuming a list of "Foo" objects with
"id" and "bar" properties:
<s:select list="listOfFoo" listKey="id" listValue="bar" value="foos"/>
See the <s:select...> tag documentation [1].
If you're building the options by hand:
<select name="foos">
<c:forEach value="${listOfFoos}" var="foo">
<option value="${foo.id}">${foo.bar}</option>
</c:forEach>
</select>
(You'd also need logic to determine if the option should be selected.)
Some of the information on the tag syntax page [2] might also be of interest.
