[jboss-user] [EJB/JBoss] - Re: mapping 0..1 association

anonymous wrote : I tried using OneToMany annotation along with nullable set to true, but that doesn't work. Associations are "optional" by default. To enforce 1..* or 1..1 associations, you'd have to do: @ManyToOne(optional = false) What exactly isn't working? Are you using the "mappedBy" property correctly? Example: | @Entity | public class A { | ... | @OneToMany(mappedBy = "myA") | public List<B> getBList() { | return bList; | } | ... | } | | @Entity | public class B { | ... | @ManyToOne | public A getMyA() { | return myA; | } | ... | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3984235#...
