We are facing a problem of compilation messages of JDK are displayed in Norwegian. I am suggesting of workaround for this problem.
If you are using a Linux then export "LANG = en_US" in your .profile file. Then default language for your profile changes to US English and all the compilation messages will be in English.
On Windows machine for default command prompt above trick will not work. But there is another option as download the cygwin software (http://cygwin.com/) and compile your programs from cygwin command prompt by exporting the LANG environment variable to get messages in English.
Also I am attaching a PDF which suggests changing the default language from windows machine. http://www.endnote.com/support/helpdocs/Changing%2520Regional%2520Settings%2520in%2520Windows%2520XP.pdf
After performing steps , IE started displaying messages in English but the windows options are shown in Norwegian.
Hope this will help.
