Question

Don’t be to hard on me, this is my first try with JSF.

I have a ManagedBean with ApplicationScope which shall hold some information for all visitors. Now it should be able to change the information in this bean, but I want that done from some other bean.

How can I link my beans? Is there some autowire annotation or how do you build a datastructure with more than one bean?

Answer 1

With JSF2 you can inject one bean into another bean.

Inside faces-config.xml use the following to inject visitorBean to appScopeBean.

<managed-bean>
    <managed-bean-name>appScopeBean</managed-bean-name>
    <managed-bean-class>com.app.AppScopeBean</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
    <managed-property>
        <property-name>visitorBean</property-name>
        <value>visitorBean</value>
    </managed-property>
</managed-bean>

Don’t forget to add visitorBean field (with getters and setters) inside AppScopeBean.
