Hi, thanks for you reply. <property name="hibernate.hbm2ddl.auto" value="update" /> All it says in addition to the above is the following: 16:12:18,321 INFO [Ejb3Configuration] found EJB3 Entity bean: eu.mpulse.commons.repository.customers.Account | 16:12:18,331 INFO [Ejb3Configuration] found EJB3 Entity bean: eu.mpulse.commons.repository.customers.Customer | 16:12:18,712 INFO [AnnotationBinder] Binding entity from annotated class: eu.mpulse.commons.repository.customers.Account | 16:12:18,712 INFO [EntityBinder] Bind entity eu.mpulse.commons.repository.customers.Account on table accounts | 16:12:18,672 INFO [AnnotationBinder] Binding entity from annotated class: eu.mpulse.commons.repository.customers.Customer | 16:12:18,672 INFO [EntityBinder] Bind entity eu.mpulse.commons.repository.customers.Customer on table customers | 16:12:21,236 ERROR [SchemaUpdate] Unsuccessful: alter table accounts add index FK809DBBE624CB3F8D (customer_id), add constraint FK809DBBE624CB3F8D foreign key (customer_id) references customers (id) | 16:12:21,236 ERROR [SchemaUpdate] Duplicate key name 'FK809DBBE624CB3F8D' but those messages all seem related to the original problem to me.
