Looks like you have a @OneToMany(mappedBy="serviceGroup") association inside your Service entity, but the mappedBy property refers to another type ( ServiceGroup ). I think it should be @OneToMany(mappedBy="service") instead. Same thing for ServiceMethod , it should be @OneToMany(mappedBy="serviceMethod").
