何か奇妙なことが起こっています。DBに何かを書き込むことになっているEJB3を作成しましたが、HSQLDBが接続を拒否するたびに:

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

しかし、私は2.2.8を使用しています。これは、Mavenによってリンクされているため、間違いはありません。

これは私のhibernate.cfg.xmlです

<?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="hibernate.connection.username">sa</property>

        </property>
        <property name="hibernate.session_factory_name">
            hibernate/HSQLDBSessionFactory
        </property>

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

        <property name="hbm2ddl.auto">create</property>

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

EJBで何をしているのか:

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

そして私の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;
    }
}

何か案が?ありがとう=D

JBossに含まれているhsqldb.jarをHSQLDBバージョン2.2.8jarに置き換える必要があります。
