Hi Frnds, I'm new to EJB & have a basic doubt in oneToOne.

I used Cutomer & Address entities with oneToOne relation.
If I don't specify @JoinColumn, @PrimaryKeyJoinClumn in the @oneToOne relationship, It works fine without any error.

Is it mean that priamykeyJoinColumn is taken by default?

Thanks in Advance.

primarykeyjoincolumn is not defined default. when you define only @onetoone annotation, the persistence provider automatically joins using the primar keys only. whereas using primarykeyjoincolumn , we have option to have define relationship's between column's.
