Quando testo as mensagens criadas no arquivo jsf_messages.properties recebo o seguinte erro: "javax.servlet.ServletException: Can't find bundle for base name jsf_messages, locale en_US"
Meu faces-config.xml esta assim:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.1"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_1.xsd">
<application>
<message-bundle>jsf_messages</message-bundle>
</application>
</faces-config>O arquivo jsf_messages.properties está no diretório src/main/resources/
