Can you try with JPA-QL instead of sql?

Or when you call addEntity. Try putting the full package/classname as the String. "org.stockdomain.domain.Stock"


I never use SQL with addEntity, I would always use JPA-QL myself, but that doesn't mean that what you did was wrong.

so JPA-QL would be

String ql = "Select * from Stock"
return sessionFactory.getCurrentSession().createQuery(ql).list();

I suggest trying with JPA-QL to see what the real problem could be. Is it the String "Stock" or something more than just that.

Hi mark,

After trying so many options/solutions, finally the reason was found : A jar was missing -->javassist.jar
I noticed that it's defined as a dependency in the pom of hibernate, but eclipse/maven (m2) didn't download !!!

thanks a lot,

Frank

Sweet. Lots of fun when the actual problem is not what shows.
