How can I get localized Error messages for basic errors ?

Question

I'm running JDK 1.6
and I wrote :
Locale.setDefault(Locale.CANADA_FRENCH);
                try
                java.io.File f = new java.io.File("c:/temp/xxnonexistentx");
                byte aa[] = new byte[2];
                java.io.FileInputStream fis = new java.io.FileInputStream(f);
                fis.read(aa);
                fis.close();
                catch (Exception e)
                    System.err.println(" Err " + e.getLocalizedMessage());
        }And I get
Err c:\temp\xxx (The system cannot find the file specified)why do I always get the US English error message. This is really a basic error, why does it seem that there is no localized version in French ?
I also tried with
        Locale.setDefault(Locale.GERMAN);But I always get English �ber Alles !
WHY ?

Answer 1

As a developper I prefer my error messages in my
langage. .NET does it (if I want), I like it. Do you
know that O'Reilly & Flanagan Java reference book
(1500 pages) in French sells very well in France ?
Not so much the English version.As I said, I sympathize to some extent. With this part, yes.
End-users do see some error messages (this file not
found is an example), you want, me and all other
people, to translate this type of messages in how
many languages, each separately, over and over ?If I'm an end-user I don't want to see Java error messages. Or if I must, I only want to see them in the context of "This error message occurred, please pass it on to the technical support people when you call them". So, given that, I don't care if the system only produces German messages. This part I don't sympathize with.
