The problem seems to be with the Java Runtime having problems reading the system locale. My system locale is set to UK, but when I run a test program (code below) I get the date formatted to a US locale instead of UK. I ran the same program under 1.4.2_03 on win xp, and 1.4.2_04-b05 on win2k which both worked fine. Running the same program under 1.4.1_03 on win xp and win 2k results in the problem. Does anyone know of a workaround to this problem without upgrading to 1.4.2_03 or higher? Also does anyone know what the minimum version we should have if we did decide to upgrade JRE's? Thanks, Jonathan import java.util.*; import java.text.*; public class LocaleTest { public static void main(String[] args) { DateFormat format = DateFormat.getDateInstanc(DateFormat.SHORT); format.setCalendar(Calendar.getInstance()); format.getCalendar().set(Calendar.MILLISECOND,0); format.getCalendar().set(Calendar.SECOND,0); format.getCalendar().set(Calendar.MINUTE,0); format.getCalendar().set(Calendar.HOUR,0); System.out.println("date is "+ format.format(format.getCalendar().getTime())); } } Back to top zoopy Guest Posted: Tue Aug 24, 2004 6:17 pm    Post subject: Re: Locale problems in 1.4.1_03-b02 On 24-8-2004 17:16, JMM wrote: Quote: I'm having issues dealing with Locale under 1.4.1_03-b02.

Note: GB, not UK Quote: Also does anyone know what the minimum version we should have if we did decide to upgrade JRE's? Don't know, but I'd go for the latest release of 1.4.2 (which is _05 at the time of this writing). The release notes normally contain a list of bugs that have been fixed by that release.

The reason is because my users won't go for the upgrade and they're located all over the world. Do you know of a workaround that uses the systems locale and the date formatter will properly use it too?

Do you know of a workaround that uses the systems locale and the date formatter will properly use it too? There's not much that I can think of, considering these restrictions. You could check the Java bugdatabase to see if there are workarounds for the problem. As you probably know, you can programmatically change the default locale (Locale.setDefault(...)), but that maybe would mean that you have to change your program and have the users upgraded (well, with new version of your program, not the JRE), a way you seemed no to want to go. Otherwise you could play around with Window's regional settings, and see if that brings a solution. Yet, then you would have to instruct every user to change their settings, possibly causing problems with other applications they have. So, this doesn't seem the proper direction either. -- Regards, Z.

Thanks again for the update. I realized I was incorrect with the original issue. It seems that the JRE 1.4.1 does pick up the correct Locale, but either the DateFormat and/or Calendar classes are ignoring the Locale. Do you have any suggestions/workarounds in getting the DateFormat and/or Calendar to acknowledge the correct Locale?

Jonathan IIRC there's DateFormat.getDateInstance(format,locale) and Calender.getInstance(locale) Thanks for all the assistance. It turns out there wasn't a problem with any of the classes that I mentioned. The problem was that we're using the US version of 1.4.1 and not the international version. Sorry for the mistake.
