Way to sort / enforce order for Map.entrySet?

Hi,

Does anyone know how to sort a map.entrySet by the value? Each entry
is an Integer mapped to a String, but I wish to have the whole thing
sorted alphabetically by the strings. Any ideas how I can do this?
Below is the function that ultimately serves up the map.entrySet.
(The Map[] object is a list returned from a database).

Thanks, - Dave

    @ModelAttribute("promoEntryTypes")
    public Set<Map.Entry<String, String>>
populatePromoEntryTypes(@ModelAttribute("appInterface")
JspAppInterfaceAdmin appInterface) {
     final Map<String, String> map = new TreeMap<String, String>();
     try {
     if (appInterface != null) {
     Map[] promoEntryTypes = appInterface.getUserPromotionTypes();
     for (int i=0; i<promoEntryTypes.length; i++) {
     map.put(((Integer) promoEntryTypes[i].get("id")).toString(),
(String) promoEntryTypes[i].get("promotion_name"));
     } // for
     } // if
     } catch (Exception e) {
     log.error(e.getMessage(), e);
     }
     return map.entrySet();
    }
