se a linha essa:
dao.adiciona(projeto); provavelmente é o dao que tá null… como você está criando esse dao? recebendo no construtor?
Isso mesmo
o ProjetoDao tá assim:
package modelos;
import hibernate.HibernateUtil;
import java.util.List;
import org.hibernate.Session;
import org.hibernate.Transaction;
//import br.com.caelum.vraptor.ioc.Component;
//@Component
public class ProjetoDao {
private Session session;
public ProjetoDao(){
this.session = new HibernateUtil().getSession();
}
public void adiciona(Projeto p){
Transaction tx = session.beginTransaction();
session.save(p);
tx.commit();
}
public void atualiza(Projeto p){
Transaction tx = session.beginTransaction();
session.update(p);
tx.commit();
}
public void remove(Projeto p){
Transaction tx = session.beginTransaction();
session.delete(p);
tx.commit();
}
@SuppressWarnings("unckecked")
public List<Projeto> lista(){
return session.createCriteria(Projeto.class).list();
}
}
e no controller, quem cria o dao? você recebe no construtor?
isso mesmo
package Controller;
import java.util.List;
import modelos.Projeto;
import modelos.ProjetoDao;
import br.com.caelum.vraptor.Resource;
import br.com.caelum.vraptor.Result;
@Resource
public class ProjetoController {
private ProjetoDao dao;
public ProjetoController() {
this.dao = dao;
}
public void formulario() {
}
public void adiciona(Projeto projeto) {
dao.adiciona(projeto);
}
public void atualiza(Projeto projeto) {
dao.atualiza(projeto);
}
public void remove(Projeto projeto) {
dao.remove(projeto);
}
public List<Projeto> lista() {
System.out.println("isso é um teste");
return dao.lista();
}
}
aqui:
private ProjetoDao dao;
public ProjetoController() {
this.dao = dao;
} vc colocou o dao nele mesmo… precisa receber como parâmetro no construtor.
private ProjetoDao dao;
public ProjetoController(ProjetoDao dao) {
this.dao = dao;
} o eclipse deve até ter te dado um warning, às vezes é importante ver isso 
Putz, agora eu tomei essa exception aqui

deu algum pau na inicialização da classe HibernateUtil… deve estar no log de inicialização do servidor.
se vc está usa o VRaptor vc não precisa dessa classe, de qqer forma… vc pode registrar o pacote do hibernate e receber a Session direto no construtor do dao.
http://vraptor.caelum.com.br/documentacao/componentes-utilitarios-opcionais/
Man, eu to tentando usa o container do Spring, mas eu não sei como que eu configuro o VRaptor pra isso, e também não entendi o que eu tenho que coloca no CustomProvider, tem como dá uma esclarecida nisso ai???
vc não precisa configurar nada… basta ter os jars do spring no classpath…
vc não precisa do CustomProvider, só do context-param do packages com o valor do pacote do hibernate…
chegou a ler a apostila? http://www.caelum.com.br/curso/fj-28-vraptor-hibernate-ajax/
e fazer o curso? http://www.caelum.com.br/curso/online/vraptor/
Realmente eu não fiz o curso online, mas tava tentando acompanha a apostila quando deu todos esses erros . . . . . . . lendo a documentação mais atentamente eu percebi uns vacilos que eu tava cometendo por bobera . . . . . . vo rele tudo e i fazendo passo a passo
vlws 
Estou novamente com problemas . . . . . . eu recomecei meu projeto e acho que agora esta tudo certo, porém ocorrem erros quando tento starta o tomcat
abaixo está o erro e o meu web.xml
um help por favor

geralmente é problema de versão de jar. vê se tem mais de um jar do slf4j (tem que ter um slf4j e um slf4j-log4j)
tem um só de cada . . . . . . será que pode ter alguma coisa a ver com a versão???
e essas partes, não tem problema??

qual é a versão do slf4j que vc tá usando? tenta trocar a versão (ex usar a que vem com o vraptor)
a versão é essa ai, já era a mesma (slf4j-api-1.6.1.jar) mas eu subistitui todos os jars pelos que vem no vraptor, agora mudo o erro:
será incompatibilidade do log4j com a versão do hibernate??
o que eu acho estranho é ele não conseguir iniciar o contexto da aplicação

}Blz, agora o problema é que não tem ninguém criando a Session do hibernate…
você pode criar um componente que faz isso, ou usar o que já vem com o VRaptor, no 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>se já existir a configuração de packages, basta colocar os valores separados por vírgula
agora deu isso
GRAVE: Exception starting filter vraptor
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactoryCreator': Invocation of init method failed; nested exception is org.hibernate.HibernateException: /hibernate.cfg.xml not found
at org.springframework.beans.factory.annotation.InitDestroyAnnotationBeanPostProcessor.postProcessBeforeInitialization(InitDestroyAnnotationBeanPostProcessor.java:133)eu tava usando o persistence.xml
ele não funciona???
se tá usando o persistence.xml troca o hibernate por jpa no context-param
