Hibernate version:
2.1
JBoss 4.1

Code between sessionFactory.openSession() and session.close():
We are using the JTATransactionManager and everything was working great when all of a sudden, we starting getting crazy errors. We go to login which worked fine but now it returns a null list. As well we have been getting errors such that org.apache.struts.action.RequestProcessor Null pointer exception. Another is NoClassDefFound. All of these with unchanged code that worked 5 minutes before. Any clue?

After JBoss had been running for a time it would say it was out of sessions or something to that affect. I have read that there is a bug that it marks transactions for rollback but that does not actually ever happen. We would simply redeploy the app and all was well. Not any more.

I have posted to the Jboss site as well but thought I would put it here too.

Full stack trace of any exception that occurs:

Name and version of the database you are using:
Sybase ASE 12.5

Debug level Hibernate log excerpt:
Debug

Here is an update on my current error verbatm:

WARN [org.apache.struts.action.RequestProcessor] Unhandled Exception thrown: class java.lang.NullPointerException

ERROR [org.jboss.web.localhost.Enginer]
StandardWrapperValve[projName]:Servlet.service() for projName threw exception java.lang.NullPointerException at ../../../../../.HibernateUtil.getSession()

The .getSession class:


session = HibernateContext.getSession(java:hibernate/SessionFactory);


Hmmmm.


Also I noticed that when I redeploy the jboss server, I print out two of my logger messages that have to do with a class called: Roles.java. These are application roles not once for jboss or the db?????? Why would this happen on deploy?

Ok, I put try catch around the HibernateContext.getSession();

Here is what prints out:
org.jboss.util.NestedRuntimeException: Unable to retrieve Session; - nested throwable: (net.sf.hibernate.HibernateException: Session cannot be generated outside of transaction scope) at org.jboss.hibernate.session.HibernateContext.getSession(HibernateContext.java:108) at HibernateUtil.getSession(...)
