title: Dynamically generate a list of available languages in Spring MVC
body: <p>I have set up i18n in Spring MVC 3, and it is working correctly.
  There are several files, each with its own language: messages_en.properties, messages_de.properties, etc.</p>
  
  <p>In one of my JSPs, I need to show the users a combo with all available languages, and I would like this list to be dynamic i.e. generated on the fly from the existing language files in the server.</p>
  
  <p>Is there any built-in method to generate this list? Or do I have to resort to check the folder where the language files reside and parse them?</p>
  
  <p>Thanks!</p>
