Try the same tutorial using a MySQL databse with InnoDB engine and having a Many2Many relationship and an identifying One2Many relationship and you will see that: The scaffolding capacities in Netbeans do not support : handling Many2Many relationships in JSF pages and Creating a child object in a OnetoMany relationship returns a weird exception (Foreign Key constraint through EclipseLink).
That makes the netbeans scaffolding using JPA for MySQL absolutely useless! That s a big petty!
I managed to develop a big project using Netbeans hopefully because the database had no Many-to-many relationship from the start. So I started with the scaffolding and extended the code progressively…….

Please try it and see by yourself!

It  creates  Facelets for CRUD capabilities (Create.xhtml, Edit.xhtml, List.xhtml, and View.xhtml)
