Ajuda com mapeamento JPA + Persistence (RESOLVIDO)

Programação Java
#1

Estou precisando de uma ajuda para criar meu arquivo persistence e configurar a criação das tabelas no banco a partir das beans.

Segue minha classe bean:

package Model;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

/**
 *
 * @author Andre
 */

@Entity
public class Login {
	
	@Id
	@GeneratedValue
	private Long id;
	
	private String senha;
	private static String login;

	public static String getLogin() {
		return login;
	}

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

	public Long getId() {
		return id;
	}

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

	public String getSenha() {
		return senha;
	}

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

Minha persistence:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
  <persistence-unit name="Login" transaction-type="RESOURCE_LOCAL">
	<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
	<class>Model.Login</class>
	<properties>
	  <property name="javax.persistence.jdbc.url" value="jdbc:postgresql://localhost:5432/church2"/>
	  <property name="javax.persistence.jdbc.user" value="postgres"/>
	  <property name="javax.persistence.jdbc.driver" value="org.postgresql.Driver"/>
	  <property name="javax.persistence.jdbc.password" value=""/>
	  <property name="hibernate.dialect" value=" org.hibernate.dialect.PostgreSQLDialect" />
	  <property name="hibernate.show_sql" value="true"/>
	  <property name="hibernate.format_sql" value="true"/>
	  <property name="hibernate.hbm2ddl.auto" value="update"/>
	</properties>
  </persistence-unit>
</persistence>

Estou tentando criar a tabela com o seguinte código:

public static void main(String[] args) {
	// TODO code application logic here
	EntityManagerFactory factory = Persistence.createEntityManagerFactory("Login");
	factory.close();
}
}

Mas está gerando um erro gigantesco…

Não sei o que pode estar errado… preciso mesmo de uma luz de vcs galera!

#2

Consegui remover o erro adicionando o jar do postgre novamente no classpath.
Mas agora ele gera outro erro:

Exception in thread "main" org.hibernate.DuplicateMappingException: The [Model.NewEntity] and [newchurch.NewEntity] entities share the same JPA entity name: [NewEntity] which is not allowed!

Mas já apaguei essas classes que foram alguns testes que fiz! Não sei aonde elas ainda podem estar abertas… já fechei o netbeans e abri mas o erro persiste!

#3

Está mapeando em persistence.xml ou hibernate.properties ou hibernate.cfg.xml?

#4

Boa tarde brother…
Estou mapeando com persistence.xml

#5

Pode postar esse arquivo?

#7

Opa…
Segue…

Cara, pelo erro, vc está usando 2 classes como entidade que possuem o mesmo nome, e o mecanismo da JPA chiou. Mude o nome de uma dessas classes ai.

#9

Opa! Boa tarde brother!!!
Ae que tá irmão, eu já até excluí as outras classes entende?
Deixei apenas essa login mas o erro persiste!

#10

Irmão! Consegui resolver aqui…
Não sei porque mas o netbeans havia criado um package e nele ainda estavam essas duas classes, exclui, dei um clean no projeto e agora criou a tabela lindamente!!!
Obrigado pela força pessoal… vou alterar o tópico para RESOLVIDO!
