[b]Hibernate version: 2.1[/b]

[b]Weblogic version: 8.1[/b]

Hi, All:

Integrating Weblogic and Hibernate can be a little bit of a struggle. I am trying to place the SessionFactroy in the JNDI tree but having trouble. Is there a good example online on how to do this?

This is what I've done:

added this line to my hibernate.cfg.xml file

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

Then I used the code as mentioned in Hibernate In Action in a Hibernate Manager class that resides in the WebLogic App Server space:

try {
System.out.println("Initializing Hibernate in JNDI Tree");
new Configuration().configure().buildSessionFactory();
// SessionFactory is now in JNDI, see hibernate.cfg.xml
System.out.println("Successfully Initializing Hibernate in JNDI Tree");
} catch (HibernateException e) {
System.out.println("Could not place Hibernate Session Factory in JNDI Tree");
e.printStackTrace();
}

So far so good. This code ran fine.

Then I tried a lookup. Didn't work. Here's my lookup code.........

try {
Context ctx = new InitialContext();
String jndiName = "java:hibernate/HibernateFactory";
sessionFactory = (SessionFactory)ctx.lookup(jndiName);
} catch (NamingException ex) {
System.out.println("Could not obtain Session Factory from JNDI Tree");
ex.printStackTrace();
}

Here's my log exception:

javax.naming.NameNotFoundException: While trying to look up /hibernate/Hibernate

Any help would be great. I can get Hibernate to work within Weblogic as a Singleton class but can't get the SessionFactory obtained from the JNDI tree. Also, I would like to be able to eventually make use of Weblogic services, such as transactions, etc.

Can anyone help?

Thanks,
