[EJB 3.0] - Re: How to define unique constraint on foreign keys ? - jboss-user

Saturday, 13 October 2007

According to spec you can use 

  | @javax.persistence.JoinColumn(name = "EMPLOYE_FK",unique=true)
  | 

However, if you are creating the schema from scratch I suggest you use a @OneToOne
relationship which does exactly what you want.
