Explanation

In EJB 2.x, Container-Managed Persistence (CMP) fields are not declared as variables in the bean class. Instead, they are defined as virtual properties via abstract getter and setter methods. The actual mapping and field definitions are specified in the deployment descriptor's abstract persistence schema.
