Hello gavin,

Dear Sir,

Could you be kind enough to teach me how to access the hibernate jndi
java:/hibernate/HibernateFactory using the correct jndi lookup or method?

Thanks

eh?

I have no idea. I don't know anything about your appserver and unless its WebSphere I wouldn't have a clue anyway.

Please don't address questions to me directly - there are lots of other people in the forum who will be much better equipped to help you if you give sufficient information.

Hi,


application server is jboss-3.2.2 , does this helps?

In your SAR or JMX deployment service descriptor you will have a line similar to this (This is what I have).

<attribute name="JndiName">java:/HibernateFactory<attribute>

In you EJB code (SLSB/DAOs) you will have to lookup the JNDI name. eg.

InitialContext context = new InitialContext();
SessionFactory factory = (SessionFactory) context.lookup("java:/HibernateFactory");

Thats all that is needed. There is information on JBoss and Hibernate in the Wiki and a number of examples exist aswell.

I use a hibernate.cfg.xml file and specify my session-factory as (using your given JNDI name, mine would be without that first slash):

=-=-=-==-=-=-==-=-=-==-=-=-==-=-=-=
<session-factory name="java:/hibernate/HibernateFactory">
...
</session-factory>
=-=-=-==-=-=-==-=-=-==-=-=-==-=-=-=

To perform the lookups for the session factory, I do the following calls:

=-=-=-==-=-=-==-=-=-==-=-=-==-=-=-=
import javax.naming.Context;
import javax.naming.InitialContext;

try {
String jndiLocation = "java:/hibernate/HibernateFactory";
Context ctx = new InitialContext();
SessionFactory sf = (SessionFactory) ctx.lookup(jndiLocation);
Session session = sf.openSession();

} catch ( NamingException ne ) {
// do something here (up to you)
} catch ( HibernateException he ) {
// do something else here (up to you)
}

=-=-=-==-=-=-==-=-=-==-=-=-==-=-=-=

That's it. I don't modify my server.xml, web.xml or anything else. I take the lazy road and let hibernate initialize everything when I setup the configuration the first time.

Regards,
David

hello -
i am new to hibernate and have encountered a similiar problem, which 66.html fixed for me. however, this quote:



is something that has me a bit confused. since i have packed up hibernate in a SAR mbean do i still need to setup a configuration file as well? the docs are very clear on this.

thanks,
jason

Jason,

Since making my post, I've found out that if you don't modify the server.xml file but simply use a hibernate.cfg.xml with <session-factory name="some:jndi/name" ... /> then you end up with a JNDI instance that you can only access from that local webapp. If you need to share your hibernate sessionFactory between webapps, you will need to modify your server.xml file.

Personally, I haven't mixed webapps to all use the same hibernate SessionFactory, so this isn't an issue for me, yet.

David
