Adding Managed Bean Declarations

After developing the backing beans to be used in the application, you need to configure them in the application configuration resource file so that the JavaServer Faces implementation can automatically create new instances of the beans whenever they are needed.

The task of adding managed bean declarations to the application configuration resource file is the application architect’s responsibility. Here is a managed bean declaration for UserNumberBean:

<managed-bean>
    <managed-bean-name>UserNumberBean</managed-bean-name>
    <managed-bean-class>
        guessNumber.UserNumberBean
    </managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
    <managed-property>
        <property-name>minimum</property-name>
        <property-class>long</property-class>
        <value>0</value>
    </managed-property>
    <managed-property>
        <property-name>maximum</property-name>
        <property-class>long</property-class>
        <value>10</value>
    </managed-property>
</managed-bean>

This declaration configures UserNumberBean so that its minimum property is initialized to 0, its maximum property is initialized to 10, and it is added to session scope when it is created.

A page author can use the unified EL to access one of the bean’s properties, like this:

<h:outputText value="#{UserNumberBean.minimum}"/>
