I have a simple web application with JavaServer Facase framework and when i deploy tomcat return :

Element type "resource-bundle" must be declared.
Element type "base-name" must be declared.
Element type "var" must be declared.


this is my code

faces-config.xml

 <?xml version="1.0" encoding="UTF-8"?>
 
<faces-config xmlns="http://java.sun.com/JSF/Configuration">
    <application>   
        <locale-config>
            <default-locale>en</default-locale>
            <supported-locale>bg</supported-locale>
        </locale-config>        
    </application>  
  
    <resource-bundle>
        <base-name>SKMsystem.messages</base-name>
        <var>msgs</var>
    </resource-bundle>     
    
    <managed-bean>
        <managed-bean-name>userBean</managed-bean-name>
        <managed-bean-class>SKMsystem.userBean</managed-bean-class>
        <managed-bean-scope>session</managed-bean-scope>
    </managed-bean>  
    
    <navigation-rule>
        <from-view-id>/index.jsp</from-view-id>
        <navigation-case>
            <from-outcome>check</from-outcome>
