[jboss-user] [EJB 3.0] - ArrayList Mapping

[poyge394]

Hi, 
I have an Object Rollingstock, inside Rollingstock I have a collection off Vehicles.
Hear is the mapping:

  | @JoinTable( name="vehicles", 
  | joinColumns= @JoinColumn( name= "fk_rollingstock"),
  | inverseJoinColumns= @JoinColumn( name="id_vehicle") )
  | public Collection<Vehicle> getVehicles() { return vehicles; }
  | public void setVehicles(ArrayList<Vehicle> vehicles) { this.vehicles = vehicles;}	
  | 
when i try to persist an Roolingstock i get this error:

  | 19:41:54,218 ERROR [property.BasicPropertyAccessor] expected type: java.util.ArrayList, actual value: org.hibernate.collection.Pe
