It binds a user interface to objects accessible via unified expression language. Any CDI bean can be assigned a name and therefore be available for JSF applications to take advantage of. All that is required is to annotate the CDI bean with a named annotation, and it can be referred to directly in a JSF page. Okay, let's go to the IDE and see a simple example. So the simplistic sample of how this works is to display a value of a field of a CDI bean in a web page. So for this, all I need are two things. A bean and a JSF web page. So here I have the user bean. And as you can see it has only one property, and that's the name property. As you can see on line 20, I have already assigned a name to the name field.
