Every time I try to delete my persistent object I get this exception:
org.hibernate.MappingException: Unknown entity: java.lang.Long
I am using the spring open session in view filter. I am trying to delete an object after the session that retrieved it has been closed. However I am trying to reassociate the object with a new session in my dao delete method by calling getHibernateTemplate().update(entity);
Here is my delete method and my mapping file and my exception. Could someone please help? Thanks
Code:
public void delete(final T entity)
{
getHibernateTemplate().update(entity);
getHibernateTemplate().delete(entity.getEntityId());
}
Code:
