Migrated from NovaTec Jira. Original ticket: INSPECTIT-905
From the Spring version 3.2 the support for the Hibernate 3 is decreasing and we should move away from HibernateTemplate to Hibernate 4 as the JPA provider. The DAOs should use the EntityManager interface, as a standard in JEE applications. In addition, we need to move away from the XML mappings and change them with Annotation.
