Notice that the above JPA entity does not use the @GeneratedValue annotation,
therefore the value for its primary key needs to be explicitly set before persisting
its data.
The following CDI Named bean acts as a controller in our example application, it
has a method that is meant to persist data in an instance of the Customer JPA entity.
package com.ensode.nbbook.buggywebapp.controller;
//imports omitted for brevity
public class CustomerController {
@PersistenceContext(unitName = "BuggyWebAppPU")
