I was trying to include translations in my website, german and english. Sadly i seem to be to stupid to do it right and can't spot the problem. Can someone tell my why my language wont load? It always sticks with the default language.properties file and wont change to language_de / language_en
Here is my faces-config
<?xml version="1.0" encoding="UTF-8"?>
<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>de</default-locale>
<supported-locale>en</supported-locale>
</locale-config>
<resource-bundle>
<base-name>language</base-name>
<var>language</var>
</resource-bundle>
</application>
</faces-config>
Here is my project structure
Here is the component i use to change the language
<p:link id="buttonHeader_languageLink">
<p:graphicImage id="buttonHeader_languageIcon"
value="#{languageBean.currentLanguage.graphicPath}"
onclick="#{languageBean.changeLanguage()}"></p:graphicImage>
</p:link>
and my ManagedBean
#ManagedBean
#SessionScoped
public class LanguageBean implements Serializable {
private static final long serialVersionUID = 1L;
private final static SessionLanguage GERMAN = new SessionLanguage(new Locale("de"), "/resource/image/german.png");
private final static SessionLanguage ENGLISH = new SessionLanguage(new Locale("en"), "/resource/image/english.png");
private SessionLanguage currentLanguage = GERMAN;
public SessionLanguage getCurrentLanguage() {
return currentLanguage;
}
public void changeLanguage() {
if(currentLanguage.equals(GERMAN)){
currentLanguage = ENGLISH;
}else{
currentLanguage = GERMAN;
}
FacesContext.getCurrentInstance().getViewRoot().setLocale(currentLanguage.getLocale());
}
}
And this is the response header after clicking the link which seems to be missing the language :/
