Olá galera, estou começando com jsf2 e criei um arquivo formulario.xhtml, sendo que quando chamo o mesmo no browser , ele me retorna :
HTTP Status 404 -
type Status report
message
description The requested resource () is not available.
Quanto inicio o servidor ele já da um erro também de ClassNotFoundExcpetion , segue a stacktrace :
Grave: Servlet /JFS2-JPA2 threw load() exception

Segue minha classe Java :
package br.com.jsf;
import javax.faces.bean.ManagedBean;
@ManagedBean
public class NumeroAleatorio {
private int maximo;
private int numeroAleatorio;
public String geraNumeroAleatorio(){
this.numeroAleatorio = (int) (Math.random() * this.maximo);
return "resposta";
}
public int getMaximo() {
return maximo;
}
public void setMaximo(int maximo) {
this.maximo = maximo;
}
}
Meu arquivo formulario.xhtml :
