JSF – message bundle always uses default properties file

internationalizationjsflocaleresourcebundle

I cannot get locales to work.

System

EAR and WAR

Glassfish: 3.12
Hibernate 4.2 – jar's on EAR and WAR
Mojarra: 2.1.11
Primefaces: 3.3
Omnifaces: 1.1

Property files in source folder:

messages_de.properties <- using german language
messages.properties <- using english language

faces-config.xml:

<locale-config>
    <default-locale>en</default-locale>
    <supported-locale>de</supported-locale>
</locale-config>
<message-bundle>messages</message-bundle>
<resource-bundle>
    <base-name>messages</base-name>
    <var>msg</var>
</resource-bundle>

Problem:

Example the label and all other texts using the message bundle are wrong: 

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://java.sun.com/jsf/core" 
    xmlns:h="http://java.sun.com/jsf/html">
    <f:view locale="de">
        <h:head>
            <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
        </h:head>
        <h:body>
            <h:form>
                <h:outputLabel for="postalcode" value="#{msg.postalcode_u}: *"/>
                <h:inputText id="postalcode" label="#{msg.postalcode_u}" required="true"/>
                <h:commandButton value="#{msg.save_u}"/>
            </h:form>
        </h:body>
    </f:view>
</html>

Required validation message: Default validation messages use the correct language.

Wrong message: Postalcode: Überprüfungsfehler: Wert ist erforderlich.
It should be: Postleitzahl: Überprüfungsfehler: Wert ist erforderlich.

Setup:

Glassfish 3.1.2
Mojarra 2.1.6 and also tested with 2.1.11

Edit:

1.
Using FacesContext.getCurrentInstance().getViewRoot().getLocale() to look into the same message resource bundle to display some custom faces messages does not work.

2.
I also have a second message bundle, currently also in source folder which is only accessed by the beans to display error messages:

errorMessages_de.properties
errorMessages_en.properties

Those error messages created inside the bean are localized correctly using FacesContext.getCurrentInstance().getViewRoot().getLocale()!

3.
"Forcing" german language using following config still does not work. Messages are still retrieved from messages.properties and not messages_de.properties.

<locale-config>
    <default-locale>de</default-locale>
    <supported-locale>de</supported-locale>
</locale-config>

New edit:

When i start the server i get this warning:

Edit2:

The error message above is not relevant for the problem. See my own answer.

Best Answer

There was an entry value in the properties file that escaped a german umlaut using utf-8 coding.

ü -> \u00FC

The problem was, that I missed the last C which made the properties file somehow unreadable!

Can't believe no appropriate error message was printed. If it could not be escaped why not just print the value like its done in many cases.

But that warning message is still present.
