Thank you, great. Prepersist did help. Still, with above scenario I have the problem with id. It supposed to be auto generated. However, when I add @GeneratedValue I am getting the exception on startup: ObjectName: persistence.units:ear=spot4.ear,unitName=spot4 State: FAILED Reason: javax.persistence.PersistenceException: org.hibernate.HibernateException: Missing sequence or table: hibernate_sequence I Depend On: jboss.jca:service=DataSourceBinding,name=spot4Datasource With the old variant of Hibernate this auto sequence generated worked with the following annotation used in Doclet: /** * @hibernate.id column="ID" generator-class="increment" unsaved-value="0" */ Again, any suggestions?
