@PostConstruct Example Using Stateless Session Beans and CDI

There was a question posed about using @PostConstruct to initialize JSF fields from a database on the NetBeans Java EE Forum. I thought I would write a quick example of how to use @PostConstruct to initialize a list of customers, and select one to display.

This example also includes using a stateless session bean directly with the @Named annotation from Context and Dependency Injection (CDI).

All of this was accomplished using NetBeans 7.0.1.
