Hi to all, I am currently working in JDE 4.6 . In my application, I need to apply the language localization facility with the languages, such as Spanish, French and Portuguese. I am currently developing in English Language. Please anyone help to develop this localization settings to apply in my application as per the user selection. Thanks in advance, Packiaraj M

Not 100% clear on what you are asking, but the following code when invoked will change the default language to French:

Locale.setDefault(Locale.get(Locale.LOCALE_fr, null));

If this does not help, can you please clarify what you would like to be able to do..

Thanks for your reply peter,

Actually i need to change my application default language programatically if i select french language means it will need to change the application label,textbox and every thing in the application to french.

Is this possible? Got my point?

Thanks,

Packiaraj M

The following code should show you how this can be done.  This was a test program I created to test how the DateTime field would look in various languages.  Not production code.....

import net.rim.device.api.i18n.*;
import net.rim.device.api.system.*;
import net.rim.device.api.ui.*;
import net.rim.device.api.ui.component.*;
import net.rim.device.api.ui.container.*;
import net.rim.device.api.io.http.HttpDateParser;
 
public class LanguageTestScreen extends MainScreen
                                implements FieldChangeListener {
 
    static String [] LANGUAGES = new String [] { "English", "French", "Spanish" };
    ObjectChoiceField _languageChoice = new ObjectChoiceField("Select Language:", LANGUAGES);
    DateField _testDateField = null;
    DateField _testDateField2 = null;

    private SimpleDateFormat sdFormatDate = new SimpleDateFormat("EEE dd MMM yyyy");
    private long _dateToDisplay = HttpDateParser.parse("2010-04-17");
 
    public LanguageTestScreen() {
        super();
        this.add(_languageChoice);;
        _languageChoice.setSelectedIndex(0);
        fieldChanged(_languageChoice, 0);
        _languageChoice.setChangeListener(this);
    }
 
    public void fieldChanged(Field f, int context) {
        int langIndex = _languageChoice.getSelectedIndex();
        if ( langIndex == 0 ) {
            Locale.setDefault(Locale.get(Locale.LOCALE_en, null));
        } else
        if ( langIndex == 1 ) {
            Locale.setDefault(Locale.get(Locale.LOCALE_fr, null));
        } else {
            Locale.setDefault(Locale.get(Locale.LOCALE_es, null));
        }
        if ( _testDateField != null ) {
            this.delete(_testDateField);
            this.delete(_testDateField2);
        }
        sdFormatDate = new SimpleDateFormat("EEE dd MMM yyyy");
        _testDateField = new DateField("Test1: ", _dateToDisplay, sdFormatDate);
        this.add(_testDateField);
        _testDateField2 = new DateField("Test2: ", _dateToDisplay, DateField.DATE);
        this.add(_testDateField2);
    }
}

Thanks for your help peter..

if i need to install that particular language? 

i have tried your code in storm2 simulator its not change the language....

[peter_strange]

You should test my code on a Simulator.  I think most simulators have French and Spanish installed.

You install/remove languages as part of the Device OS.  The easiest way I find is to connect your Storm 2 to a Desktop Manager, and go through the process to update the OS.  You should see the languages that you add in there.

Ok fine thanks peter.. but if my user dont have these language in real device means.... how can i install automatically when my application launch, do u have any idea..?

[peter_strange]

I am not aware of any way your application would be able to add language support to the device.  If the language is not there, I think the best you can do is tell the user.
