Hi, I'm having difficulties understanding how to persist a bean/pojo/class with a collection holding another pojo. How should I go about solving the following example:

I have these two entities:

and I've created a database with these tables:

Now let's say that I already have an author with a populated bibliography and I want to persist this to the database.

What I already tried was using hibernates merge by calling this method:

Like this

Unfortunately this doesn't seem to work as the foreign key author_id in books is never set (NULL).

What should I be doing different?
