Cannot set default locale for JSF

Question

I'm using this code but I can't set default locale other than english. I tried this with latest Mojarra version:

faces-config.xml:

<?xml version="1.0"?>
<faces-config xmlns="http://xmlns.jcp.org/xml/ns/javaee"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
            http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"
              version="2.2">
    <application>
        <locale-config>
            <default-locale>bg</default-locale>
            <supported-locale>en</supported-locale>
            <supported-locale>bg</supported-locale>
        </locale-config>
        <resource-bundle>
            <base-name>com.web.common.ints.Text</base-name>
            <var>text</var>
        </resource-bundle>
    </application>
</faces-config>

Java class to load properties files:

public class Text extends ResourceBundle
{
    protected static final String BUNDLE_NAME = "com.web.common.ints.text";
    protected static final String BUNDLE_EXTENSION = "properties";
    protected static final Control UTF8_CONTROL = new UTF8Control();

    public Text()
    {
        setParent(ResourceBundle.getBundle(BUNDLE_NAME,
            FacesContext.getCurrentInstance().getViewRoot().getLocale(), UTF8_CONTROL));
    }

    @Override
    protected Object handleGetObject(String key)
    {
        return parent.getObject(key);
    }

    @Override
    public Enumeration getKeys()
    {
        return parent.getKeys();
    }

    protected static class UTF8Control extends Control
    {
        public ResourceBundle newBundle(String baseName, Locale locale, String format, ClassLoader loader, boolean reload)
            throws IllegalAccessException, InstantiationException, IOException
        {
            // The below code is copied from default Control#newBundle() implementation.
            // Only the PropertyResourceBundle line is changed to read the file as UTF-8.
            String bundleName = toBundleName(baseName, locale);
            String resourceName = toResourceName(bundleName, BUNDLE_EXTENSION);
            ResourceBundle bundle = null;
            InputStream stream = null;
            if (reload)
            {
                URL url = loader.getResource(resourceName);
                if (url != null)
                {
                    URLConnection connection = url.openConnection();
                    if (connection != null)
                    {
                        connection.setUseCaches(false);
                        stream = connection.getInputStream();
                    }
                }
            }
            else
            {
                stream = loader.getResourceAsStream(resourceName);
            }
            if (stream != null)
            {
                try
                {
                    bundle = new PropertyResourceBundle(new InputStreamReader(stream, "UTF-8"));
                }
                finally
                {
                    stream.close();
                }
            }
            return bundle;
        }
    }
}

When I open the web page he locale is always in english? How I can set custom locale locale?

Do you have some idea how I can fix this issue?

I used this tutorial: http://jdevelopment.nl/internationalization-jsf-utf8-encoded-properties-files/

So I changed this line:

 private Locale locale = FacesContext.getCurrentInstance().getViewRoot().getLocale();

To:

locale = FacesContext.getCurrentInstance().getExternalContext().getRequestLocale();

If I use the original code I get NPE. But with the second code I get always en as default locale.

Answer 1

Doesn't the locale come from the browser? The locale is english b/c your browser is running on a system that says its locale is english. Under windows, I installed the spanish language pack and then I can control the default locale, or at least the locale the browser is asking for by switching the computer and opening a new browser, if I remember correctly.

<?xml version="1.0" encoding="UTF-8"?>
<faces-config version="2.0" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://java.sun.com/xml/ns/javaee
        http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd">
    <application>
        <locale-config>
            <default-locale>en</default-locale>
            <supported-locale>es</supported-locale>
            <supported-locale>zh</supported-locale>
        </locale-config>
        <resource-bundle>
            <base-name>i18n.Text</base-name>
            <var>text</var>
        </resource-bundle>
    </application>
</faces-config>

and

@ManagedBean
@SessionScoped
public class LocaleBean implements Serializable {
    private static final long serialVersionUID = -2786895465419133453L;

    private Locale locale;

    @PostConstruct
    public void init() {
        locale = FacesContext.getCurrentInstance().getViewRoot().getLocale();
    }

    public Locale getLocale() {
        return locale;
    }

    public String getLanguage() {
        return locale.getLanguage();
    }

    public void setLanguage(String language) {
        locale = new Locale(language);
        FacesContext.getCurrentInstance().getViewRoot().setLocale(locale);
    }

}

and

<p:submenu label="#{text['menu.language']}" style="float:right">
<p:menuitem value="#{text['menu.language.english']}" action="#{localeBean.setLanguage('en')}" oncomplete="location.reload(true)" />
<p:menuitem value="#{text['menu.language.spanish']}" action="#{localeBean.setLanguage('es')}" oncomplete="location.reload(true)"/>
<p:menuitem value="#{text['menu.language.chinese']}" action="#{localeBean.setLanguage('zh')}" oncomplete="location.reload(true)"/>

and then various i18n/Text_en.properties, i18n/Text_es.properties, i18n/Text_zh.properties.
