The EJB project uses Hibernate 3.5 for persistence and the datasource JNDI in hibernate.cfg.xml is jdbc/connectionname which is defined in the properties of the embeddable container.

I am pretty sure i dont want to wait until the UPDATE_MODEL since i believe that might be a security risk. Though a little more uncertain if i should let the phase run
