Setting sun.locale.formatasdefault to true in Java 7

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, in Java 7 there is an error in Locale.getDefault (). However, as recommended by Oracle, I set the system property "sun.locale.formatasdefault" to true. Despite the fact that now I get my m / c Locale, it always displays as en_US, although my m / c Locale is set to fr_BE.

Here is the result of the above code that 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 could be causing? Thank you very much in advance.

You need to set this system property before by running your JVM. You can do this with command line arguments:

 java -Dsun.locale.formatasdefault=true TargetClass

Or in environments where you do not control the start of the JVM, you can set it through the _JAVA_OPTIONS environment _JAVA_OPTIONS :

  • * Nix

     export _JAVA_OPTIONS=-Dsun.locale.formatasdefault=true

  • for windows

     SET _JAVA_OPTIONS=-Dsun.locale.formatasdefault=true

On Windows, if you want the change to be applied not only for this CMD, but for the entire system, you create the Windows system variable JAVA_TOOL_OPTIONS
