Essentially I would like to have a messages.properties files external to the jar files in my application. So that users can add languages and edit the files easily if my translations are wrong

at the moment i use

ResourceBundle.getBundle("package.MessageBundle");

But i would like to do something like this

ResourceBundle.getBundle("lang/MessageBundle");

Where lang is a folder under my application installation directory.

1. is this a good idea (if not, why not)?
2. can someone point me in the right direction, or some sample code that does this

thanks

Alex
