Tag! You’re it
August 17, 2006Now tagging… 
This is how it works:
1. Grab the nearest book.
2. Open the book to page 123.
3. Find the fifth sentence.
4. Post the text of the next 3 sentences on your blog along with these instructions.
5. Don’t you dare dig for that “cool” or “intellectual” book in your closet! I know you were thinking about it! Just pick up whatever is closest.
6. Tag three people.
In particular, the problem makes cascade save (discussed later in this chapter) useless for sets. We strongly discourage this solution (database identifier equality). A better way is to include all persistent properties of the persistent class, apart from anyy database identifier property, in the equals() comparison.
This is from the book “Hibernate In Action” by Christian Bauer and Gavin King
