Tiago, All interfaces marked with @MessageBundle or @MessageLogger generate concrete classes at compile-time. Getting a locale implementation of a @MessageBundle by default uses the Locale.getDefault(). You can specify a locale too when getting an implementation. I would suggest creating static variables, generally placed on the interface, for each locale if they're aren't too many. Something like: @MessageBundle(projectCode = "example") public interface MessageExample { MessageExample MESSAGES = Messages.getMessage(MessageExample.class); MessageExample MESSAGES_DE = Messages.getMessage(MessageExample.class, Locale.GERMANY); @Message("Example message 1") String exampleMessage(); @Message("Example Error: %s") IllegalStateException exampleExcetion(@Cause Throwable cause, String errorMessage); } On 01/15/2013 06:23 AM, Pete Muir wrote: -- James R.
