Hi:
  According to error message, it seems that you have the duplicated <url-pattern> in the web.xml,please modify them to use seperate <url-pattern>.
          <servlet-mapping>
                <servlet-name>Faces Servlet</servlet-name>
                <url-pattern>*.faces</url-pattern>
        </servlet-mapping>
        <servlet-mapping>
                <servlet-name>faces</servlet-name>
                <url-pattern>*.faces</url-pattern>
        </servlet-mapping>
