Configuring managed beans in XML

JSF managed bean configuration was essentially improved starting with JSF 2.0. Most commonly, a managed bean is annotated with @ManagedBean and another annotation indicating a JSF scope (for example, @RequestScoped). But managed beans can be configured in faces-config.xml as well, and this approach is not deprecated or obsolete. The simplest configuration contains the managed bean's name, class, and scope:

<managed-bean>
  <managed-bean-name>playersBean</managed-bean-name>
  <managed-bean-class>book.beans.PlayersBean</managed-bean-class>
  <managed-bean-scope>request</managed-bean-scope>
...
</managed-bean>

Note

In case that you need a managed bean that should be eagerly initialized, you can use the eager attribute of the <managed-bean> tag:

<managed-bean eager="true">

Managed beans' properties can be initialized from faces-config.xml using the <managed-property> tag as follows...
