Hi,

While trying to play with hibernate for first time, I'm trying to run one
of the example.
I have dataSource mapped in app-server with a JNDI name and I'am able to access that DataSource if I run a lookup (JNDI) for it but when
try to do following I'm getting DataSource not found error.

SessionFactory factory =
new Configuration().configure().buildSessionFactory();


Anybody any ideas as what I'm missing?

Thanks.

I do have hibernate.cfg.xml file so I'm assuming I do NOT need to have hibernate.properties in my classpath?

Here is my XML look like:

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">

<!-- Generated file - Do not edit! -->

What is your application server?

wblogic 7.x

I've just noticed something in the doc (http://www.hibernate.org/34.html)

...WebLogic Server's JNDI implementation is known to be incompatible with Hibernate. Questions regarding this issue should be directed to BEA, since it it due to their lack of support for a fairly non-exotic part of the JNDI spec...


IS THAT REALLY TRUE? Any details?


Thanks

Supposedly it is for binding Hibernate to JNDI, but not for Hibernate getting things out of JNDI.

If you look at the stack trace, you see that the problem has to do with InitialContext being unable to load an initial context factory. Typically this is done by setting the following:

System.setProperty(javax.naming.Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory"); // or whatever they call it in 7x
System.setProperty(javax.naming.Context.PROVIDER_URL, "t3://yourhost");

Also, weblogic binds the default UserTransaction under javax/transaction/UserTransaction; so this element should become:
<property name="jta.UserTransaction">javax/transaction/UserTransaction</property>

Yeah, I actually passed that point and added information related to JNDI url etc in my mapping file and that changed the output exception to some marshalling parameter exception and this situation matches with the argument made about the inability of Weblogic JNDI to work with Hibernate. I've also noticed some work around in a FAQ for that but still need to give it a try. http://www.hibernate.org/74.html

My purpose was to test out hibernate and see how the lazy loading
works. So, ended up using straight up JDBC connection and things started to roll.

Thank you all!
