I'm a rookie at using Hibernate, so please bear with me.
I have User object that has a one-to-many mapping to a Resume object. I am getting the exception below when trying to persist the resume.
I believe I might be doing something wrong with the addMethod method on my DAO. The passed in "resume" object already has a "user" object set on it.
public Resume addResume(Resume resume)
throws DAOException
{
User user = null;
Session ses = null;
try
{
ses = sessionFactory.openSession();
// validate that a user exists for this resume
if (resume.getUser() == null) {
throw new DAOException("No user assigned to resume!");
}
ses.save(resume);
ses.flush();
ses.connection().commit();
}
catch (Exception e)
{
try { ses.connection().rollback(); }
catch (Exception ex) { e.printStackTrace(); };
throw new DAOException(e);
}
finally
{
try { ses.close(); }
catch (Exception ex) { ex.printStackTrace(); };
}
return resume;
}
