java.util.MissingResourceException: Can't find bundle for base name resources.application, locale en

Question

My faces-config.xml likes below.

<?xml version="1.0" encoding="UTF-8"?>

<faces-config
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"
version="2.0">
<application>
    <message-bundle>resources.application</message-bundle>
    <locale-config>
        <default-locale>en</default-locale>
    </locale-config>
</application>

</faces-config>

Xhtml file

<f:loadBundle basename="resources.application" var="msg"/>

I am getting the below exception

javax.faces.view.facelets.TagAttributeException: //D:/12c_Workspace/VNPO/WebContent/login.xhtml @9,59 <f:loadBundle basename="resources.application"> Can't find bundle for base name resources.application, locale en

How is this caused and how can I solve it?

Answer 1

Exception clearly says that you don't have a application_en.properties or at least application.properties file in the resources package in the runtime classpath.

That's really it. Just make sure you have one.

Unrelated to the concrete problem, I just want to warn that <message-bundle> and <f:loadBundle> are mutually exclusive. To learn about the difference, head to Internationalization in JSF, when to use message-bundle and resource-bundle?

Answer 2

You need 2 things:

1. To have your messages.properties file in your class-path. The safest bet is to put it under src/main/java/your/package/name
2. Configure it in your faces-config.xml:

http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd" version="2.2">

    <application>
        <resource-bundle>
            <base-name>your.package.name.messages</base-name>
            <var>i18n</var>
        </resource-bundle>
    </application>

</faces-config>

Note that you don't include .properties suffix in faces-config.xml
