Java: HTTP Status 500 – Internal Server Error

Programação Java
#1

Boa tarde pessoal.
Obrigado desde já a todos pela ajuda.
Estou iniciando o aprendizado em programação para web java EE. Estou utilizando como servidor o tomcat versão 8.5. Estou construindo uma aplicação web seguindo um tutorial. Me deparei com o seguinte erro quando rodo a aplicação:

# HTTP Status 500 – Internal Server Error

Type Exception Report

Message Servlet.init() for servlet [Faces Servlet] threw exception

Description The server encountered an unexpected condition that prevented it from fulfilling the request.

Exception

Note The full stack trace of the root cause is available in the server logs.

Apache Tomcat/8.5.46

Gostaria de saber se alguém pode me ajudar a decifrar esse erro aqui por favor.

#2

Fiz a adição de duas bibliotecas:

jsf-api.jar
jsf-impl.jar

Agora o erro é outro. Observe.
