Which Application server are you using?

I'm using JBoss 3.0.8 + MySql.

Thanks,
Luk.

Follow the steps:
1. Create jBoss-Hib-Service.xml and put it in the deploy directory. The purpose is to create a service and register at JNDI, so that it can use to interact with DB using Hibernate.
Following is an example(This I generate using xDoclet.):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE server>
<server>
            <mbean code="net.sf.hibernate.jmx.HibernateService" name="jboss.jca:service=HibernateLaborMgmt">
         <depends>jboss.jca:service=RARDeployer</depends>
                <attribute name="MapResources">org/learn/labormgmt/employee/value/EmployeeValues.hbm.xml,org/learn/labormgmt/customer/value/CustomerValues.hbm.xml,org/learn/labormgmt/location/value/StateValues.hbm.xml,org/learn/labormgmt/association/value/AssociationValues.hbm.xml</attribute>
       <attribute name="JndiName">java:/hibernate/labormgmt</attribute>
       <attribute name="Datasource">java:/labormgmt</attribute>
       <attribute name="Dialect">org.hibernate.dialect.SAPDBDialect</attribute>
       <attribute name="ShowSql">true</attribute>
       <attribute name="UserTransactionName">UserTransaction</attribute>
       <attribute name="TransactionStrategy">org.hibernate.transaction.JTATransactionFactory</attribute>
       <attribute name="TransactionManagerLookupStrategy">org.hibernate.transaction.JBossTransactionManagerLookup</attribute>
   </mbean>
</server>

2. In the code get the service, which is actually a Session factory. e.g. code:
 try {
//JNDI lookup to get Hibernate Session factory.
    SessionFactory factory = (SessionFactory)ServiceLocator.getInstance()
        .getService("java:/hibernate/labormgmt");
      
    } catch (HibernateException e) {
      logger.debug("Error while initilising Hibernate." + e.getMessage());
      throw new InstantiationError("Error while initilising Hibernate."
          + e.getMessage());
    } catch (LocatorException e) {
      logger.debug("Error while initilising Hibernate." + e.getMessage());
      throw new InstantiationError("Error while initilising Hibernate."
          + e.getMessage());
    }

3. Start using it for creating Hibernate Session.
    Session session = null;
    session = factory.openSession();

I hope it helps you.

Same question with Jonas server ...
Ways more difficult to find than Jboss outhere !
