Richfaces: problem with facesconfig

[asmaa kellal]

hello

i started working with RichFaces to decorate my page and I succeeded to create menu but when I added facesconfig to define the rules of navigation when I compile my page an error message appears

         

In-place deployment at C:\Documents and Settings\utilisateur\Mes documents\NetBeansProjects\richfaces\build\web deploy?path=C:\Documents and Settings\utilisateur\Mes documents\NetBeansProjects\richfaces\build\web&name=richfaces&force=true failed on GlassFish v3 Domain C:\Documents and Settings\utilisateur\Mes documents\NetBeansProjects\richfaces\nbproject\build-impl.xml:607: The module has not been deployed. FAILURE OF THE GENERATION

the same if I leave the facesconfig empty like this

    
<!-- =========== FULL CONFIGURATION FILE ================================== -->

<faces-config version="2.0"
    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">


</faces-config>
