Ive done this, everyone is overcomplicating it greatly...
Lookup.getData() gets an ArrayList of states.
This array list is loaded through an XML file that loads upon boot and puts
it in a static variable. This XML file can load it from itself or from the
database. It does all the .add() .add() .add() etc. This should NOT be done
in a jsp tag. Done once and pulled from static method like below. Nice and
simple.
Here's the JSP code.
....
<% pageContext.setAttribute("allUnitedStates",
Lookup.getData(Constant.GLOBAL.UNITED_STATES)); %>
....
<bean:message key="prompt.state"/>
<html:select property="state" size="1">
<html:option value=""></html:option>
<html:options name="allUnitedStates" labelName="allUnitedStates"/>
</html:select>
