As per the EJB3 spec, Vector is not supported collection type for OneToMany mapping:
anonymous wrote : 
  | Collection-valued persistent fields and properties must be defined in terms of one of the following collection-valued interfaces regardless of whether the entity class otherwise adheres to the JavaBeans method conventions noted above and whether field or property-based access is used:
  | java.util.Collection, java.util.Set, java.util.List[4], java.util.Map.[5]
  | For collection-valued persistent properties, type T must be one of these collection interface types in the method signatures above. Generic variants of these collection types may also be used (for example, Set).
