Hi

I have found a peculiar thing in Hibernate :

Session.createCriteria(Class persistentClass) doesn't throw any exception even if class is not loaded in the Session through mappings file.

e.g.


returns blank list even though TempVO class is not specified in mapping.hbm.xml


Is there any way we can capture this type of error?

when we are query DB without mapping resource in hibernate.cfg.xml throu HQL, it shows Error. but in Criteria it doesn't through any error.

It's a sample code and it's stack Trace.

Configuration config=new Configuration();
config.configure("/hibernate.cfg.xml");
SessionFactory sf=config.buildSessionFactory();
Session session=sf.openSession();
Criteria c=session.createCriteria(Report1.class);
List test=c.list();
for(int i=0;i<test.size();i++)
System.out.println(test.get(i));
Iterator results=session.createQuery("from Report1 r").iterate();
while(results.hasNext())
{
Report1 r=(Report1)results.next();
System.out.println(r.getName());
}

Stack Tarce
