Boa noite pessoal
estou estudando Hibernate e ao tentar criar uma tabela no banco a partir do Hibernate esta dando essa mensagem,
alguma idéia de como resolver isso?

Obrigado
Ola,
Como voce esta mapeando sua classe para a criacao da tabela : por annotations ou por xml ?
Se possivel poste o codigo que mostre esse mapeamento e se for por xml alem do hbm.xml e da classe poste o hibernate.cfg.xml para que posse ser avaliado.
Flw.
Oi Daniel,
estou usando annotations
class Pessoa.java

import javax.persistence.Temporal;
import javax.persistence.TemporalType;
@Entity
@Table(name=“pessoa”)
public class Pessoa implements Serializable {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="pessoa_id")
private Long id;
@Column(name="nome")
private String nome;
@Column(name="email")
private String email;
@Column(name="senha")
private String senha;
@Column(name="cpf")

public void setId(Long id) {
this.id = id;
}
public Long getId() {

}
public Date getDataNascimento() {

}
public void setDataNascimento(Date dataNascimento) {
this.dataNascimento = dataNascimento;
}
public String getSenha() {

Ola,
Aparentemente parece tudo certo com seu codigo, mas quero saber umas coisas :
1 - Voce ja tentou trocar o dialeto que esta usando no XML para :
Se nao, teste isso mude o dialeto e tente rodar novamente.
2 - Outra coisa se no console ele gerar algum sql de criacao da tabela , teste o sql diretamente no banco e veja se funciona tambem.
E eu to vendo ali no erro que ele falhou bem na hora de fazer o Export do Schema se der poste a classe onde voce esta fazendo o SchemaExport pra que possa dar uma olhada, se ta tudo certo tambem.
Da uma olhada aqui tambem se nao resolver : http://www.guj.com.br/posts/list/93993.java
quem sabe ajude.
Flw.
Daniel,
o link que você passou não ajudou muito. 
troquei o dialeto e continua com o mesmo problema.
class GerarTabelas
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.cfg.Configuration;
import org.hibernate.tool.hbm2ddl.SchemaExport;
public class GerarTabelas {
public static void main(String[] args) {
Configuration cfg = new AnnotationConfiguration();
cfg.configure();
SchemaExport se = new SchemaExport(cfg);
se.create(true, true);
}
}
Ola,
Seu código aparetemente está certo, mas vejo no erro que todo o problema está relacionado com que sua aplicação não está conseguindo se comunicar com o banco.
Por isso te pergunto, o seu banco está rodando normalmente (digo sozinho) ?, o schema em seu banco já existe?
Pois o Hibernate só criará as tabelas pra voce e nao o Schema do banco.
Veja o erro está justamente nessa linha :
17:28:56,673 ERROR SchemaExport:274 - schema export unsuccessful
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
Eu encontrei um forum onde o pessoal solucionou este problema, de uma olhada :
http://forums.netbeans.org/post-14735.html
Flw.
Daniel,
o banco funciona normal, consigo acessar ele pelo mysql query browser e pelo administrator. O shema eu criei vazio, justamente para o Hibernate criar as tabelas.
Li os links que voce me mandou e eles falavam para comentar a opção skip-network da inicialização do mysql, foi o que eu fiz e agora a mensagem
da exceção mudou:

ninguem passou por isso que possa me ajudar? :?:
Você tá usando MySQL, né? O banco tá criado? Se tiver, digita mysqld --console e tenta devolta.
Fiz o que você falou mas continua dando o mesmo erro.
[root@linux gregory]# /etc/rc.d/mysqld --console
usage: /etc/rc.d/mysqld {start|stop|restart}
[root@linux gregory]# mysqld --console
090916 12:17:37 [ERROR] Fatal error: Please read "Security" section of the manual to find out how to run mysqld as root!
090916 12:17:37 [ERROR] Aborting
090916 12:17:37 [Note] mysqld: Shutdown complete
Na verdade, isso é erro de que você não tem permissão. Você tem a senha de root da máquina aí?
Mostra os bancos que você tem criado.
Fala André,
Tenho a senha de root sim, segue um print com os bancos
http://imagebin.ca/view/ph2P2n8i.html
Opa, cheguei meio tarde, mas não dá nada. Você tem isso:
Né? Mas você não tem o banco chamado ‘jsf’ criado.
