the following code will help illustrate my problem:

import java.util.Locale;
import java.text.*;

public class LocaleTest {
   public static void main(String[] args) {
      System.out.println(Locale.getDefault());
      System.out.println("java-version-" +System.getProperty("java.version"));
      System.setProperty("sun.locale.formatasdefault","true");
      System.out.println("prop:" +System.getProperty("sun.locale.formatasdefault"));
      System.out.println("getLocale-" +Locale.getDefault());
   }
}

As we know, there is bug in Java 7, in Locale.getDefault().However as recommended by Oracle I have set the system property 'sun.locale.formatasdefault' to true. Even though I am now getting my m/c Locale, it is always showing as en_US even though my m/c Locale is set to fr_BE.

Here is the output of above code, which is compiled and run on Java 1.7.0_09:

en_US
java-version-1.7.0_09
prop:true
getLocale-en_US

Any thoughts on what might be causing thus? Many thanks in advance.

You need to set that system property before starting up your JVM. You can do this via command line arguments:

java -Dsun.locale.formatasdefault=true TargetClass

Or in environments where you don't control the launching of the JVM, you can set it via _JAVA_OPTIONS environment variable:

  • *Nix

    export _JAVA_OPTIONS=-Dsun.locale.formatasdefault=true

  • Windows

    SET _JAVA_OPTIONS=-Dsun.locale.formatasdefault=true

In Windows, if you want the change to be applied not only for that CMD but systemwide, you create a Windows System Variable JAVA_TOOL_OPTIONS

  • thanks for your reply, can you please elaborate how to set system property before starting up JVM.If I run the program as java -Dsun.locale.formatasdefault=true className then it works.I need to this works on application where there are number of classes,then how I do that. – vish Nov 29 '12 at 12:25
  • That's exactly how you would specify the property before startup. You can also set the property up in your environment before launching your program or IDE, or even on a per program level ***within*** the IDE – Perception Nov 29 '12 at 12:43
  • thanks Perception, I am very much close to the answer but having little confusion on this, so can you please elaborate that how to set SET sun.locale.formataadefault=true Windows in environment property i.e which file needs to be changed. – vish Nov 29 '12 at 13:05
  • Heres how you set your environment variables on Windows, hope this helps - http://vietpad.sourceforge.net/javaonwindows.html – Perception Nov 29 '12 at 15:18
  • Setting environment variables has no effect. However, you can use `_JAVA_OPTIONS` environment variable: `set _JAVA_OPTIONS=-Dsun.locale.formatasdefault=true`. See [*Information about `_JAVA_OPTIONS`*](http://stackoverflow.com/q/17781405/572834) for more. – Alexey Ivanov Jul 27 '15 at 13:54
