Here is a custom localized selectItem creator from enums.
Assumes you have a resource bundle configured in faces config.
It also expects values for each Enum Value.
If you have this enum:
package com.exampe;
public enum Example {
EXAMPLE
}
Then the appropriate entry in the message bundle would be:
com.example.Example.EXAMPLE=example
public static List<SelectItem>
createSelectItemsFromEnum(FacesContext context, Class<? extends Enum>
value) {
List<SelectItem> list = new ArrayList<SelectItem>();
Application a = context.getApplication();
String msgBundle = a.getMessageBundle();
Locale locale = context.getViewRoot().getLocale();
ResourceBundle rb = ResourceBundle.getBundle(msgBundle, locale);
Set<? extends Enum> set = EnumSet.allOf(value);
if (set != null && set.size() > 0) {
for (Enum e : set) {
String name = value.getName() + "." + e.name();
list.add(new SelectItem(e, rb.getString(name)));
}
}
return list;
}
I have also a Converter that uses the same method from and to Enums if
you'd like that. That is needed if you use standard components.

If you use jboss seam there is support for an enum converter and
enum-select item components that do just what you are looking for.
