I have a problem. I followed instruction in this tutorial. But I have a problem. When I change language from selectOneMenu, nothing happend. But default language it´s load good. This is my xhtml file:
<?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:f="http://xmlns.jcp.org/jsf/core">
<h:head>
<title>Letecký systém</title>
<h:outputStylesheet library="css" name="login.css" />
</h:head>
<h:body>
<div id="nadpis">Letecký systém</div>
<h:panelGrid columns="2">
Language :
<h:selectOneMenu value="#{mc.localeCode}" onchange="submit()"
valueChangeListener="#{mc.countryLocaleCodeChanged}">
<f:selectItems value="#{mc.countriesInMap}" />
</h:selectOneMenu>
</h:panelGrid>
<div id="mainForm">
.
.
.
.
</div>
</h:body> </html>
And this is my controller:
@ManagedBean(name = "mc")
@SessionScoped
public class MainController {
private static final long serialVersionUID = 1L;
.
.
.
.
//Translate
private String localeCode;
private static Map<String, Object> countries;
static {
countries = new LinkedHashMap<String, Object>();
countries.put("English", Locale.ENGLISH); //label, value
countries.put("French", Locale.FRENCH);
}
public Map<String, Object> getCountriesInMap() {
return countries;
}
public String getLocaleCode() {
return localeCode;
}
public void setLocaleCode(String localeCode) {
this.localeCode = localeCode;
}
public void countryLocaleCodeChanged(ValueChangeEvent e) {
String newLocaleValue = e.getNewValue().toString();
for (Map.Entry<String, Object> entry : countries.entrySet()) {
if (entry.getValue().toString().equals(newLocaleValue)) {
FacesContext.getCurrentInstance()
.getViewRoot().setLocale((Locale) entry.getValue());
}
}
}
And finally this is my faces-config.xml:
<?xml version='1.0' encoding='UTF-8'?>
<faces-config version="2.2"
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">
<application>
<locale-config>
<default-locale>en</default-locale>
<supported-locale>fr</supported-locale>
</locale-config>
<resource-bundle>
<base-name>resources.messages</base-name>
<var>msg</var>
</resource-bundle>
</application>
</faces-config>
My program has structure
- Web Pages -> index.xhtml
- Source packages
- controller -> MainController.java
- resources -> messages.properties -> messages_fr.properties
- Configuration Files ->faces-config.xml
Where is a problem?
