Barry,
You are unnecessarily creating an extra String object here:
//Create list (in a loop)
cityList.add(new String(rs.getString("city")));
instead, just use
cityList.add(rs.getString("city"));

Hi Mark,
As per Tim's suggestion I am able to use ForEach
with DynaValidatorForm.
Here is what works:
struts-config.xml:
<form-bean name="locationForm"
type="org.apache.struts.validator.DynaValidatorForm" >
<form-property
name="state"
type="java.lang.String"
initial=""/>
<form-property
name="city"
type="java.lang.String"
initial=""/>
<form-property
name="cities"
type="java.util.ArrayList"/>
</form-bean>
Action:
DynaActionForm eForm = (DynaActionForm)form;
//Create list (in a loop)
cityList.add(new String(rs.getString("city")));
eForm.set("cities",cityList);
request.setAttribute(mapping.getAttribute(), eForm);
or
request.setAttribute("locationForm", eForm);
In Jsp creates a drop down menu with cities:
<html-el:select property="city" size="1">
<html-el:option value="City">Select-A-City</html-el:option>
<c:forEach var="city" items="${locationForm.map.cities}">
<html-el:option value="${city}">
<c:out value="${city}"/>
</html-el:option>
</c:forEach>
</html-el:select>
Looks like the fine point of all of this is:
items="${locationForm.map.cities}">
