The preceding steps will add the
managed-bean
element and three elements inside of
that element: a
managed-bean-name
element, a
managed-bean-class
element,
and a
managed-bean-scope
element. You will need to edit the XML of the configur-
ation file directly to further configure this managed bean.
The
managed-bean-name
element defines the key under which the bean will be stored
in a scope. For a component's value to map to this bean, the component tag's
value
at-
tribute must match the
managed-bean-name
up to the first period.
The
managed-bean-class
element defines the fully qualified name of the JavaBeans
component class used to instantiate the bean.
The
managed-bean
element can contain zero or more
managed-property
ele-
ments, each corresponding to a property defined in the bean class. These elements are
used to initialize the values of the bean properties. If you don't want a particular property
initialized with a value when the bean is instantiated, do not include a
managed-prop-
erty
definition for it in your application configuration resource file.
If a
managed-bean
element does not contain other
managed-bean
elements, it can
contain one
map-entries
element or
list-entries
element. The
map-entries
element configures a set of beans that are instances of
Map
. The
list-entries
ele-
ment configures a set of beans that are instances of
List
.
In the following example, the
newsletters
managed bean, representing a
UISelectItems
component, is configured as an
ArrayList
that represents a set of
SelectItem
objects. Each
SelectItem
object is in turn configured as a managed
bean with properties:
