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

[fhh]

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.
