    JSF Error - Cannot find faces context

    Jeden mal, wenn ich meine Anwendung starten will bekomme ich ein Cannot find Faces Context error

    Durch das Anpasses der config-Faces.xml und web.xml habe ich das problem gefixt.
    Jetzt bekomme ich nur noch dass er den Username nicht setzen kann :-(

    Code folgt gleich !
