Java.lang.UnsupportedOperationException: The user must supply a JDBC connection

Assuntos Gerais
#1

Aew gente, to começando a ver o Hibernate com JPA seguindo a apostila do K19, e ao tentar levantar a conexão já recebi esse erro:

java.lang.UnsupportedOperationException: The user must supply a JDBC connection at org.hibernate.connection.UserSuppliedConnectionProvider.getConnection(UserSuppliedConnectionProvider.java:30) at org.hibernate.tool.hbm2ddl.SuppliedConnectionProviderConnectionHelper.prepare(SuppliedConnectionProviderConnectionHelper.java:27) at org.hibernate.tool.hbm2ddl.SchemaExport.execute(SchemaExport.java:180) at org.hibernate.tool.hbm2ddl.SchemaExport.create(SchemaExport.java:133) at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:311) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1294) at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:859) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:669) at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:126) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:51) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:33) at GeraTabelas.main(GeraTabelas.java:16)

suspeiro q seja o meu persistence.xml, mas não sei o que tem de errado:

persistence.xml dentro da pasta META-INF:

<?xml version="1.0" encoding="UTF-8"?>
<persistence 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_1_0.xsd"
 version="1.0">

    <persistence-unit name="livraria" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>

        </properties>
    </persistence-unit>

</persistence>

estou criando o projeto pelo netbeans e apenas importei o log4j
os beans estão normais:

Livro:

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

    private String nome;
    private double preco;
    private long editora_id;

        return editora_id;
    }

    public void setEditora_id(long editora_id) {
        this.editora_id = editora_id;
    }

        return preco;
    }

    public void setPreco(double preco) {
        this.preco = preco;
    }
}

Editora:

[code]

import javax.persistence.Entity;

import javax.persistence.Id;

@Entity
public class Editora {

    this.id = id;
}

public String getNome() {
    return nome;
}

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

}[/code]

#2

Seu persistence.xml me parece ok.
Talvez o persistence.xml esteja na pasta errada?
Ele deve estar na pasta META-INF junto das suas classes e não no META-INF do lado da WEB-INF (numa aplicação web).
Se isso estiver correto, pode ser que esteja faltando algum jar?
Tem o restante da exceção? Seria bom ver a causa dela, que pode ser outra coisa.

isso é o q sai no console:

quanto aos jars, eu acho que tenho todos importados já

#4

Pode postar os métodos do seu JPA? Algo como JPAUtils…

#5

Apenas para certificar 100% de que seu .xml persistence.xml está ok copie e cole com o meu:

[code]<?xml version="1.0" encoding="UTF-8"?>

<persistence-unit name="livraria" transaction-type="RESOURCE_LOCAL">
	<provider>org.hibernate.ejb.HibernatePersistence</provider>
	<properties>

		<property name="hibernate.hbm2ddl.auto" value="update"/>
		<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
		<property name="javax.persistence.jdbc.user" value="root"/>
		<property name="javax.persistence.jdbc.password" value="root"/>
		<property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/livraria"/>
	</properties>
</persistence-unit>

como eu disse, os códigos q eu criei são aqueles do 1 post, não alterei nada, o netbeans importou as classes do hibernate + jpa e jsf 2, a unica coisa que eu fiz, foi importar o log4j, que eu baixei do site oficial lá

#8

me ajuda a configurar o hibernate + jpa plz?
quais são os jars q eu tenho que importar?
acabei de fazer download do distribution 3.6 do hibernate e vou usar o eclipse.
Como não sei configurar manualmente vai ser de grande ajuda aprender isso também.
E se souberem como configurar o JSF2 eu tb aceito a ajuda :smiley:

#9

Olá André,

Na linha 12 da saída do console que você postou há o seguinte WARNING:

Este erro normalmente acontece quando você erra os nomes das propriedades JDBC. Os nomes corretos são:

javax.persistence.jdbc.user
javax.persistence.jdbc.password
javax.persistence.jdbc.url

Certifique-se que não há espaço ou erro de digitação.

#10

Olá à todos,
Estou com um problema semelhante numa aplicação JSF + Hiberante. Segue log:

Segue o filtro:

@WebFilter(servletNames = {"Faces Servlet"})
public class JPAFilter implements Filter {

    private EntityManagerFactory factory;

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        this.factory = Persistence.createEntityManagerFactory("bodyWebPU");
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        EntityManager entityManager = this.factory.createEntityManager();
        request.setAttribute("entityManager", entityManager);
        entityManager.getTransaction().begin();                         /// Segundo o Netbeans o erro é aqui

        chain.doFilter(request, response);
        try {
            entityManager.getTransaction().commit();
        } catch (Exception e) {
            entityManager.getTransaction().rollback();
        } finally {
            entityManager.close();
        }
    }

    @Override
    public void destroy() {
        this.factory.close();
    }
}

Por que não posso utilizar o entityManager.getTransaction().begin(); ? Em geral não utilizo o EntityManagerFactory para pegar a transaction e dar begin, mas estou usando um tuto que peguei e queria usar. Sei que se usasse EJB não precisava do transaction, talvez nem aqui, mas se não utilizar como controlo os comits e os rollback?

#11

Ao remover as “getTransaction()” o “bicho roda”, mas sempre que tenta acessar a base da um erro com a mesma assinatura java.lang.UnsupportedOperationException: The user must supply a JDBC connection. Já troquei o driver do mysql e nada.

#12

Para resolver tive que retirar as tag bugadas do persistence e utilizar as do hibernate:

O que era assim:

E funcionou!

Alguém poderia me explicar porque assim funciona?

Tenho um projeto web (jboss + jsf) e só funcionou utilizando a api hibernate.connection.
Tenho um outro projeto Java (desktop) e funcionou com a api javax.persistence.jdbc.

Por que isto acontece?

Obrigado.

[quote=Hulkmarciano]Para resolver tive que retirar as tag bugadas do persistence e utilizar as do hibernate:
