About Question enthuware.oce-jpad.v6.2.430 :

[peter.varga]

In the explanation of the 4th option, it's written "This is a correct bidirectional mapping based on the given tables, ..."
Isn't it so that if the OneToMany relationship is bi-directional, the source object must use the mappedBy attribute to define the mapping?
That would mean that it's not a correct mapping because mappedBy attribute is missing.

You are right. This option is wrong for this reason as well.
Fixed.
thank you for your feedback!
