Unless I'm misunderstanding you, the <html:select> tag works this way
already.
You can see this if you look at the struts-exercise-taglib.war application
bundled with Struts. It uses <html:select> in exactly the way you indicate -
with 'property' and without 'value' - and the initial selected value
corresponds to the value of the property.
You can also see this if you look at the code in SelectTag.doStartTag(),
where it says (abbreviating somewhat for clarity):
if (value != null) {
match = value;
} else {
Object bean = pageContext.findAttribute(name);
match = BeanUtils.getSimpleProperty(bean, property);
}
where 'match' is the value used to determine which item is initially
selected.
