Pessoal to tentando usar o hibernate, preciso pra um projeto que está iniciando, já estudei muito sobre ele ultimamente, na prática não consegui rodar, e pesquisei geral e aparentemente não acho o erro: i formulário roda, quando clico em cadastrar ele da erro do tomcat http 500, se nao me engano eh porque nao acha a base de dados, mas conferi tudo, caso alguém ache algum erro vejam o código.
quem puder ajudar valeu!

formulário com 3 campos pra cadastrar no banco, básico so pra exemplo mesmo: index.jsp

meu backing bean

public class userBean {
    
   private Usuario usuario;
    
   private UsuarioFacade userFacade = new UsuarioFacadeImpl();
    
      public String Cadastra(){
		userFacade.usuarioSalvar(usuario);
                    return "sucesso";
     }
	
      public List<Usuario> getUsuarios(){
		return userFacade.usuarioListar();
    }
        
}

Meu DAO Generico

public abstract class GenericDAOImpl<T, PK extends Serializable> implements GenericDAO<T, PK>{
   public final Class<T> objectClass; 
   private Session session;

    public GenericDAOImpl(final Class<T> objectClass) {
        this.objectClass=objectClass;
    }
    
    public Class<T> getObjectClass(){
       return this.objectClass;
    }
    
  
    public void salvar (final T object){
        session = HibernateUtil.getInstance();
        Transaction tx = null;
        try{
            tx = session.beginTransaction();
            session.save(object);
            tx.commit();
        } catch(final HibernateException e){
            e.printStackTrace();
            tx.rollback();
          }
        finally{
            session.close();
        }
 }
    
       public List<T> listar() {
            session = HibernateUtil.getInstance();
            final Criteria c = session.createCriteria(this.objectClass);
            return c.list();
       }
   protected abstract Criteria addFkFields(Criteria c, T Example);
             
}

Meu USUARIO DAO

public class UsuarioDAOImpl extends GenericDAOImpl<Usuario, String> {
    public UsuarioDAOImpl() {
        super(Usuario.class);
    }

    protected Criteria addFkFields(Criteria c, Usuario example) {
        return c;
    }
}

USUARIO FACADE

public class UsuarioFacadeImpl implements UsuarioFacade {
    
    private GenericDAO dao = new UsuarioDAOImpl();
    
    public void usuarioSalvar(Usuario usuario) {
        dao.salvar(usuario);
    }

    public List<Usuario> usuarioListar() {
        return dao.listar();
    }
    
}

E AQUI O USUARIO

@Entity
@Table(name="usuario")
public class Usuario implements Serializable {
    
    @Column(name="nome")
     private String nome;
    
    @Id
    @Column(name="usuario")
     private String login;
     
    @Column(name="senha")
     private String senha;
    public Usuario() {
    }

    public String getNome() {
        return nome;
    }

    public void setNome(String nome) {
        this.nome = nome;
    }

    public String getLogin() {
        return login;
    }

    public void setLogin(String login) {
        this.login = login;
    }

    public String getSenha() {
        return senha;
    }

    public void setSenha(String senha) {
        this.senha = senha;
    }
    
}

A HIBERNATE UTILITÁRIA

public class HibernateUtil {
    
   private static final SessionFactory sessionFactory;
   private static final ThreadLocal<Session> threadLocal = new ThreadLocal<Session>();
   
   static {
       try {
           sessionFactory = new AnnotationConfiguration().configure("hibernate.cfg.xml").buildSessionFactory();
          
       } catch (Throwable t) {
           throw new ExceptionInInitializerError(t);
           
       }
   }
   
   public static Session getInstance(){
        Session session = (Session) threadLocal.get();
        session = sessionFactory.openSession();
        threadLocal.set(session);
        return session;
   }
    
}

E MEU HIBERNATE CONFIG

<hibernate-configuration>
- <session-factory>
- <!--  Debug 
  --> 
  <property name="hibernate.show_sql">true</property> 
  <property name="hibernate.format_sql">true</property> 
  <property name="hibernate.use_sql_comments">true</property> 
- <!--  Config 
  --> 
  <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> 
  <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/teste</property> 
  <property name="hibernate.connection.username">root</property> 
  <property name="hibernate.connection.password">root</property> 
  <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> 
  <mapping class="model.Usuario" /> 
- <!--   thread is the short name for
			org.hibernate.context.ThreadLocalSessionContext
			and let Hibernate bind the session automatically to the thread
		
  --> 
  <property name="current_session_context_class">thread</property> 
  </session-factory>
  </hibernate-configuration>

Todos os imports corretos, todo código sem erro, porém não funfa! alguém ajuda nessa ai, ocultei apenas as interfaces, GenericDAO, UsuarioFacade. no resto o exemplo que tentei está ai mas nao roda, banco normal, fiz uma inclusão normal usando conexão com PreparedStatement...
Desculpe o tamanho do post, mas se alguém souber ai VALEU...

você está usando Spring para injetar um novo Usuario no seu BackinBean ??

caso não, você deve instanciar um novo Usuario…

eh eu tava usando spring annotations, e tirei as referencias pra tentar primeiro resolver o hibernate, realmente eu esqueci do new(), mas o erro continua o mesmo…
este é o log que sai no logtomcat quando clico em cadastrar
