HelloWorld - JSF - No ExternalContext using fallback LifecycleProvider

Boa noite.

Acabei meu curso de Java e decidi estudar alguma outra coisa.
Peguei alguns livros de JSF e estou com esse problema no meu exemplo com HelloWorld.
Claro que é um exemplo bem simples mas se eu não rodar ele não vou poder seguir adiante.
Pesquisei no GUJ mas encontrei poucos tópicos sobre esse erro. Na internet também.
O erro pode ser simples mas não conheço.

O log é esse:

Meu Bean:

package br.eti.faces;

public class HelloWorldBean {

private String message;

public HelloWorldBean() {
message = "Hello World!";
}

public void setMessage(String message) {
this.message = message;
}

public String getMessage() {
return message;
}

}
