For my app I'm using Tomcat 6.0.x and Mojarra 1.2_04 JSF implementation. It works fine, just I would like to switch now to MyFaces 1.2_10 impl of JSF.

During the deployment of my app a get the following error:

ERROR [org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/myApp]] StandardWrapper.Throwable
java.lang.IllegalStateException: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml.
A typical config looks like this;
<listener>
  <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

Here is part of my web.xml configuration:

    <servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <!-- <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> -->
        <servlet-class>org.apache.myfaces.webapp.MyFacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    ...
    <listener>
         <listener- class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
    </listener>

Has anyone experienced similar error, and what should I do i order to fix it? Thanx!
