Nullpinter exception error when loading page jsf

I have a problem that I really do not know how to solve, what happens that I am working with jsf and primeface and it turns out that when executing my project, I get this error:

Error fatal en el sistemajava.lang.Exception: This query can not be execute java.lang.NullPointerException

It seems that you are ignoring the:

      <welcome-file-list>
            <welcome-file>Movies/index.xhtml</welcome-file>
        </welcome-file-list>

El detalle que ya validé las carpetas y el archivo index está, este es mi codigo del web.xml:
