Hello Hibernate Users,
I am upgrading my legacy application from Hibernate 3.6 to 4.3. The application works fine with Hibernate 3.6. However after I upgraded application to Hibernate 4.3 I am experiencing org.hibernate.MappingException: Unknown entity: java.util.HashSet. The exception is caused on calling getHibernateTemplate().saveOrUpdate(collection); where collection is a Set of entities that application is looking to save.
The mapping configuration of these entities in the application has not undergone any change and is same as before, so I am unable to realize what is going wrong now. The application is using Spring 4.1 and Java 8 and MS SQL 2014 is the database.
Any help/pointers to help resolve the issue is appreciated.
Regards,
Nitin
