Giving Beans EL Names

To make a bean accessible through the EL, use the @Named built-in qualifier:

import javax.enterprise.context.RequestScoped;
import javax.inject.Inject;
import javax.inject.Named;

@Named
@RequestScoped
public class Printer {

    @Inject @Informal Greeting greeting;
    ...
}

The @Named qualifier allows you to access the bean by using the bean name, with the first letter in lowercase. For example, a Facelets page would refer to the bean as printer.

You can specify an argument to the @Named qualifier to use a nondefault name:

@Named("MyPrinter")

With this annotation, the Facelets page would refer to the bean as MyPrinter.
