> ## Managed Bean Creation

> Another critical function of web applications is proper management of resources. This includes separating the definition of UI component objects from data objects and storing and managing these object instances in the proper scope. Previous releases of JavaServer Faces technology enabled you to create model objects that encapsulated data and business logic separately from UI component objects and store them in a particular scope. This release fully specifies how these objects are created and managed.

> This release introduces new APIs for:

> - Evaluating an expression that refers to a model object, a model object property, or other primitive or data structure. This is done with the `ValueBinding` API.
> - Retrieving the object from scope. This is done with the `VariableResolver` API.
> - Creating an object and storing it in scope if it is not already there. This is done with the default `VariableResolver`, called the Managed Bean Facility, which is configured with the application configuration file, described in the next section.

> For more information on the Managed Bean Facility, see section Creating Model Objects.
