Question

I’m currently trying to get hibernate to send my Java EE Entities in my postgresql database using an EJB. My entity code (for testing, I use the simplest one) is :

import java.io.Serializable;

@Entity

public class Coup implements Serializable {

    private static final long serialVersionUID = 1L;

    @Column(unique=true, nullable=false)
    @Id
    private String name;

    @Column(nullable=false)
    private String jeu;

    public Coup() {
    }

    public Coup(String name, String jeu) {
        this.name = name;
        this.jeu = jeu;
    }

    public String getName() {
        return this.name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getJeu() {
        return this.jeu;
    }

    public void setJeu(String jeu) {
        this.jeu = jeu;
    }

}

and my hibernate.xml file is

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" 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_1_0.xsd">
  <persistence-unit name="PostgresDSjeeux" transaction-type="JTA">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <jta-data-source>java:/PostgresDSjeeux</jta-data-source>
    <class>Equipe</class>
    <class>Joueur</class>
    <class>Salon</class>
    <class>Partie</class>
    <class>HautFait</class>
    <class>Coup</class>
    <properties>

    <!-- <property name="hibernate.connection.driver_class" value="org.postgresql.Driver"/>  -->  
      <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
      <property name="hibernate.show_sql" value="true" />
    <!-- <property name="transaction.factory_class" value="org.hibernate.transaction.JDBCTransactionFactory" /> --> 

    </properties>
  </persistence-unit>
</persistence>

However, after I execute this

            Coup c = new Coup();
            c.setJeu("superjeu");
            c.setName("supername");
                em.persist(c);

code, the generated query that I see in the JBOSS6 log is :

14:57:59,364 INFO  [STDOUT] Hibernate: insert into Coup (jeu, name) values (?, ?)

Thanks for any answer you might provide.

Answer 1

I think that’s just a logging message from the PreparedStatement to show the bound parameters.

Did you look in the database to see what was INSERTed? That’s the only thing that matters, not the log.
