ADF Business Components Java Classes

XML Files hold the properties

Creates an instance of EntityCache for each user to point to the bookings records they are working with

oracle.jbo.server.EntityCache

Creates an instance of EntityImplfor each Bookings record for each user

oracle.jbo.server.EntityImpl

Reads the XML files

oracle.jbo.server.EntityDefImpl

Why Do We Care?

Because we can Extend and Override them
