[quote=Lucas Cavalcanti]e ainda tá dando Nullpointer no getInstance do CriadorDeSession?
bom, você pode pular essa parte da apostila, remover as classes CriadorDeSession e CriadorDeSessionFactory e colocar essa configuração no seu web.xml:
<context-param>
<param-name>br.com.caelum.vraptor.packages</param-name>
<param-value>br.com.caelum.vraptor.util.hibernate</param-value>
</context-param>
isso também já inclui o interceptor de transações, então é só usar direto a session nos seus daos.[/quote]
Lucas, só pra compreender. Então quer dizer que quando eu faço essa configuraçao no web.xml eu posso fazer isso no meu Dao:
private Session sessao;
public ProdutoDao(Session session){
this.sessao = session;
}
?
fred_cbranco, remova os jars jsp*.jar ou jstl*.jar do seu WEB-INF/lib
