Hibernate version: 2.1.5

Mapping documents: n/a

Code between sessionFactory.openSession() and session.close():n/a

Full stack trace of any exception that occurs:n/a

Name and version of the database you are using:n/a

The generated SQL (show_sql=true):n/a

Debug level Hibernate log excerpt:n/a

Can the HibernateContext.getSession() call be used from a class inside a war to obtain a session from a deployed har, if the war resides in the same container as the har? Would you need to deploy them together as an ear for this to work?

Okay so I read the other thread about "the best way to access hibernate data" and have now incorporated the UserTransaction code into the servlet I'm trying to access this from:

Code:
UserTransaction transaction = (UserTransaction)(newInitialContext()).lookup("java:/UserTransaction");
transaction.begin();
Session sess = HibernateContext.getSession(DBO_SESSION);
         
         Criteria attrCrt = sess.createCriteria( attr )
            .addOrder( Order.asc("order") );
         
         results = attrCrt.list();
         transaction.commit();


However, when I try to run this, it says UserTransaction cannot be found, is there any special configuration I have to do to get it to locate the UserTransaction? I checked jndiView of the jmx-console and verified that the name UserTransaction is bound

Here's the exception.:

Code:

Well I got past this problem. Apparently I had to use:

Code:
UserTransaction transaction = (UserTransaction)(newInitialContext()).lookup("java:comp/UserTransaction");


I had to add comp to the JNDI path.

to grab a handle on the UserTransaction. I'm still having an issue where hibernate doesn't seem to want to return any results. I'm only trying Criteria queries right now. The all keep returning empty result sets even though the tables have data. I'm not getting any errors.
