Struts2 select tag with 2 different values

I have a list with 2 properties name and prefix (from SQL), where name is the language name and prefix is the language identifier composed of 2 letters.

And I want to make something like:

<select>
  <option value="en">English</option>
  <option value="fr">French</option>
  <option value="uk">English UK</option>
</select>

I know how to do that in this way: <s:select list="#{'en':'English', 'fr':'French', 'uk':'English UK'}"/>

But how to display the results if we have a list from database, for example: <s:select list="languages.name"/>

Is is possible in Struts2 s:select tag?

Here is how this should work.I suppose you have a ArrayList of some object and this object have two properties name and prefix

So In your action class you have a ArryList something like

List<LanguageObject> languageList;

which is being populated form the DB. All you need to have following entry in your JSP

<s:select name="language" list="languageList"  label="Select a country" listKey="prefix"
listValue="name" />

where prefix and name are the 2 properties being defined in your object.
