Senhores, estou com um grave problema ao configurar o hibernate nun projeto java desde esta manhã, é o exercicio 13.6 do curso FJ21.
Minha versão do MySQL é a 6.0
Meu Eclipse é a 3.3.2
A Exception a seguir só ocorre quando o parametro se.create(boolean, boolean); é falso, ou seja, somente quando eu EXECUTO a sql gerada, quando deixo ele como false, ele me mostra a query e não gera exception. Obrigado senhores, desde já!
Aqui vai o log:

Meu hibernate properties é:
hibernate.properties
hibernate.connection.driver_class = com.mysql.jdbc.Driver
hiberntae.connection.url = jdbc:mysql://localhost/fj21
hibernate.connection.username = root
hibernate.connection.password = senha
hibernate.show_sql = true

log4j.rootLogger=warn, stdout
log4j.logger.org.hibernate=info[/code]
[b]Minha classe modelo [/b](posso dizer q é a que tem os beans né? gets e sets)
[code]Produto.java
package br.com.caelum.hibernate;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
@Entity
public class Produto {
@Id
@GeneratedValue
private Long id;
private String nome;
private String descricao;
private double preco;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
public String getDescricao() {
return descricao;
}
public void setDescricao(String descricao) {
this.descricao = descricao;
}
public double getPreco() {
return preco;
}
public void setPreco(double preco) {
this.preco = preco;
}
}Classe com método main que executa as ações
GeraTabelas.java
package br.com.caelum.hibernate;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.tool.hbm2ddl.SchemaExport;
public class GeraTabelas {
public static void main(String[] args) {
AnnotationConfiguration cfg = new AnnotationConfiguration();
cfg.addAnnotatedClass(Produto.class);
SchemaExport se = new SchemaExport(cfg);
se.create(true, true);
}
}
Eu imaginei que estava dando erro com o driver jdbc do mysql, então usei a classe factory de conexões e testei, conectou normalmente.
ConnectionFactory.java
package br.com.caelum.hibernate;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class ConnectionFactory {
public Connection getConnection() {
System.out.println("Conectando ao banco");
try {
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
} catch (InstantiationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Connection con = DriverManager.getConnection(
"jdbc:mysql://localhost/fj21", "root",
"senha");
System.out.println("Conectado");
return con;
} catch (SQLException e) {
System.out.println("Erro no getConnection");
throw new RuntimeException(e);
}
}
}Testa a conexão:
TestaConnectionFactory.java
package br.com.caelum.hibernate;
import java.sql.Connection;
import java.sql.SQLException;
public class TestaConnectionFactory {
public static void main(String[] args) throws SQLException, InstantiationException, IllegalAccessException, ClassNotFoundException {
Connection connection = new ConnectionFactory().getConnection();
connection.close();
}
}
