Hi,
I have an application that uses EJB3 and hence hibernate.
As we are finding performance issues using ejb3 we are moving to directly accessing hibernate directly.
I am testing upgrading our installation from jboss 4.0.3SP1 to 4.2.0GA and where we had code to get the hibernate sessions setup using our entities with the following code
| try {
| AnnotationConfiguration ac = new AnnotationConfiguration();
| Filter[] filters = setFilter();
| setAnnotatedClasses(ac, filters);
| sessionFactory = ac.configure().buildSessionFactory();
| break;
| } catch (Throwable ex) {
| // Log exception!
| log.error("Initial SessionFactory creation failed. Message = " + ex.getMessage(), ex);
| //throw new ExceptionInInitializerError(ex);
| }
|
|
this used to work ok for setting up the hibernate session to read all of our existing entities and settings. under jboss 4.2.0GA it comes up with the following exception.
| org.hibernate.HibernateException: cannot simultaneously fetch multiple bags
