Hi ,

To represent a One to One mapping in Database we need Primary and a Foreign key iconcepts both tables.

So there is relationship required beween these two tables

Then how does Hibernate one to one Unidirectional is possible

Thanks in advance .

You can just map the association normally, but leave out the getters/make the getters private on the side you do not want direction from.

Hi, I just made sure both classes that are joined one-to-one are setup to have the same primary key so there is no foreign key needed,

It is sorta covered in the JavaRanch Style Guide.
