Noob , How i do that ?¡
<managed-bean>
<managed-bean-name>A</managed-bean-name>
<managed-bean-class>example.A</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
<managed-bean>
<managed-bean-name>B</managed-bean-name>
<managed-bean-class>example.B</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>valueFromA</property-name>
<value>#{A.propertyFromA}</value>
</managed-property>
</managed-bean>
This assumes A has "getPropertyFromA" and B has "setValueFromA", so
just change those property names to fit your use case

Does this last one works for all type of beans (request,session
application ...) ¡?
Yes, because the faces context (application actually) already knows
the scope of every bean due to its declared scope in the
faces-context. If the bean doesn't already exist, it is created and
stored in the scope defined from the configuration file.
