<managed-property>

<value>#{requestScope.businessDelegate}</value>
</managed-property>
</managed-bean>
The above injects businessDelegate into manageMyBean. It also creates a new
instance if it is needed.
JSF IoC container is not that powerful, I prefer to use Spring and then use
the Spring delegating variable resolver.
You could also write your own JSF variable resolver and then manage the
businessDelegate w/o putting it into scope.

Hello,
why don't you simply create the instance in the constructor of the bean?
class ManageMyBean {
public ManageMyBean() {
this.businessDelegate = new com.delegates.BusinessDelegate();
}
}
best regards
