Question

Something weird is happening, I made an EJB3 wich is suposed to write something in the DB but each time HSQLDB is rejecting the connection :

a pre-9.0 client attempted to connect. we rejected them

But I’m using 2.2.8, there is no mistake since it’s being linked by maven.

this is my hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

        <property name="configurationClass">

        <property name="hibernate.session_factory_name">

        </property>

        <!-- Disable the second-level cache -->
        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
        <!-- Echo all executed SQL to stdout -->

         <!-- Mapping files -->
        <mapping class="com.th.entity.TestEntity"/>
    </session-factory>
</hibernate-configuration>

what I’m doing in my EJB :

    HibernateUtil3.getSessionFactory().getCurrentSession().persist(entity);
    HibernateUtil3.getSessionFactory().getCurrentSession().close();

And my HibernateUtil3 :

import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;

/**
 *
 * @author adam
 */
public class HibernateUtil3 {

    private static final SessionFactory sessionFactory = buildSessionFactory();//constroi a sessão

    private static SessionFactory buildSessionFactory() {
        try {
            //Configuration cfg = new Configuration();//para mapeamento xml
            AnnotationConfiguration cfg = new AnnotationConfiguration();//para mapeamento com annotations
            cfg.configure("hibernate.cfg.xml");//arquivo de configuração do hibernate
            return cfg.buildSessionFactory();
        } catch (Throwable e) {
            System.out.println("Criação inicial do objeto SessionFactory falhou. Erro: " + e);
            throw new ExceptionInInitializerError(e);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
}

any idea?
Thanks =D

You need to replace the hsqldb.jar included with JBoss with the HSQLDB version 2.2.8 jar.
