Pessoal sou novo em hibernate poderia me ajudar se é essa é a forma correta de se usa as query mesmo se sim , o pq do null no manager vlw
Bean
package bean;
imports
@ManagedBean(name = "UsuarioBean")
public class UsuarioBean {
private String usuario;
private String senha;
@ManagedProperty(value = "#{entityManager}")
private EntityManager manager;
public EntityManager getManager() {
manager = (EntityManager) Persistence.createEntityManagerFactory("SG-Persistence");
return manager;
}
public void setManager(EntityManager manager) {
this.manager = manager;
}
// get set usuario / senha
public void verificaUser(){
boolean flag = false;
flag = new UsuarioQuery(this.manager).logar(usuario, senha);
}
}
package Dao;
imports
public class UsuarioQuery {
private EntityManager manager;
public UsuarioQuery(){
}
public UsuarioQuery(EntityManager manager){
this.manager = manager;
}
public boolean logar(String login,String senha){
Query query = manager.createQuery("Select COUNT(*) from tb_usuario where "
+ "usuario= :usuario and senha = :senha");
Long result= (Long)query.getSingleResult();
query.setParameter("usuario", login);
query.setParameter("senha", senha);
if(result==1L){
return true;
}else{
return false;
}
}
}
Olha, se o problema é com o manager não tem nada haver com a query.
Não está passando para o new UsuarioQuery(this.manager) um manager null ??
isso cara tava null, ai vi que tinha q passar o nome do persistence e fiz assim mais da erro nao acha o arquivo
EntityManagerFactory emf = Persistence.createEntityManagerFactory("SGBanco");
manager = emf.createEntityManager();
o arquivo esta no caminho Projeto >>> src >>> META-INF >>> persistence.xml
persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">

Qual erro q ta dando ?
Posta ai.

Cara, esse erro não tem mais a ver com o persistence.
Ele não ta achando a classe
java.lang.ClassNotFoundException: javax.faces.webapp.FacesServlet
Veja se adicionou todas as libs do JSF no projeto.
deu esse agora

Vc precisa ler o erro 
Vc precisa dizer qual o dialeto q o hibernate irá usar.
Algo do tipo
Porém, o específico pro postgre.
ja pus o dialect mas o err continua
da o erro ao executar essa linha
EntityManagerFactory emf = Persistence.createEntityManagerFactory(“SGBanco”);
a propriedade não deveria ser somente hibernate.dialect ?
Sim !
Copiei de um local aqui para passar como exemplo pra ele.
@b10machado
Teste como o Rodrigo disse
edit:
Até me confundi.
Na verdade eu passei da forma certa ele q alterou… hehe
rsrs alterei o problema continua to usando o hibernate 3.2.2
com jpa 2.0
Tem certeza q é o mesmo problema ?
Caused by: org.hibernate.HibernateException: Hibernate Dialect must be explicitly set
dão esses erros
Caused by: javax.persistence.PersistenceException: [PersistenceUnit: SGBanco] Unable to build EntityManagerFactory

nessa ordem
