When can Hibernate SessionFactory be used?

[pirent420]

Hi all,

I have been migrating from Jboss 5.1.0 GA to 6.2.0 EAP and struggling with the Hibernate SessionFactory. As in JBoss 5, to use a Hibernate SessionFactory, I look up it via its JNDI name which is specified in the service-hibernate.xml.

<hibernate-configuration xmlns="urn:jboss:hibernate-deployer:1.0">
  <session-factory name="java:/hibernate/NvrMcSessionFactory"
                   bean="nstc:service=NvrMcHibernate">

Here is my Singleton bean (in style of Jboss 5 and EJB 3.0) that needs the sessionFactory as long as it starts up:

@Service
@Management(ServiceMBean.class)
@Depends"nstc:service=NvrMcHibernate")
@Local(BackupDbManager.class)
public class BackupDbManagerBean extends ServiceMBeanSupport implements BackupDbManager
{
    private final ListenerInitializationHelper hibListenerInitHelper =
        new ListenerInitializationHelper(
            "BackupDbListener",
            NvrMcHibernate.getSessionFactory());

The lookup code:

public synchronized SessionFactory lookup()
    {
        if (sessionFactory == null)
        {
            try
            {
                InitialContext ic = new InitialContext();
                this.sessionFactory = (SessionFactory)ic.lookup(jndiName);
            }
            catch (NamingException e)
            {
                Assert.fail("Failed to lookup hibernate session factory: " + jndiName, e);
            }
        }
        
        return sessionFactory;
    }

As far as I know, in Jboss 5, Hibernate is configured in MBean and the org.hibernate.jmx.HibernateService take care of creating SessionFactory and binds it to the specified JNDI name.

Now JBoss EAP 6 no longer supports @org.jboss.annotation.ejb.Service and the service-hibernate.xml. So I have to switch to EJB 3.1 @Singleton and @Startup annotations. For the sessionFactory configuration, I replace the service-hibernate.xml with the hibernate.cfg.xml. I also change the JNDI name from "java:/hibernate/NvrMcSessionFactory" to "java:jboss/hibernate/NvrMcSessionFactory" for new JNDI naming.

<hibernate-configuration>
 <session-factory name="java:jboss/hibernate/NvrMcSessionFactory">
  <property name="hibernate.connection.password">password</property>
  <property name="hibernate.connection.url">jdbc:mysql://192.168.103.148:3306/mydb</property>
  <property name="hibernate.connection.username">username</property>
  <property name="hibernate.dialect">nstc.framework.hibernate.NecMySQLDialect</property>
  <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
  <property name="hibernate.session_factory_name">java:jboss/hibernate/NvrMcSessionFactory</property>
 </session-factory>
</hibernate-configuration>

When I deploy my application, the singleton bean cannot found the sessionFactory via the JNDI name. I am not sure if the sessionFactory is not constructed and binding before the singleton bean startup or it is not constructed yet. I have read the Migration Guide: https://access.redhat.com/documentation/en-US/JBoss_Enterprise_Application_Platform/6.2/html/Migration_Guide/index.html.

But it seems like the it does not cover this case. I have googled but I cannot find the answer (or I do not use the right keyword).

Did I missed something? Please help me know how can I use the sessionFactory in JBoss 6 EAP simply as in JBoss 5.
