Well not quite. Actually there is already Struts object called
`LabelValueBean'. So what you create a Java Collection of
LabelValueBean objects and return the collection in your
action form bean.
List list = new ArrayList();
list.add( new LabelValueBean( "0", "January" ));
list.add( new LabelValueBean( "0", "February" ));
...
list.add( new LabelValueBean( "11", "December" ));
In the html:options tag itself. Did you know that any JavaBean
can be used. This is why `property' is set `value' (getValue())
and why `labelProperty' is set `label' (getLabel())
Good luck
