Error 404 not found - when loading project jsf with wildfly - developer studio - ubuntu

I have a small problem that I have not been able to solve, I'm starting wildfly 10 and jsf maven, etc ...

When creating the first JSF project, at the time of deploying the app I get it in the localhost: 8080 / proyectoWeb / index.jsf 404 error message.

this is my web.xml file:

<?xml version="1.0" encoding="UTF-8"?>

  </servlet>
  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>
  </servlet-mapping>
</web-app>

I appreciate your help and support. Thanks.
