Handling a callback URL in JSF2

Question

I have a JSF2 web application that i would like to receive some parameters from another web application.

Another application to redirect user to my JSF2 application using URL:
http://something.com/myjsf2app/getCallback.jsf?item=apple&color=green

I would like to know what i need to do to retrieve the following two values (item, color) in my backing bean without needing to hit on submit on getCallback.jsf.

you could use viewparams to set the parameters in a @ViewScoped @ManagedBean

<h:body>
    <f:metadata>
        <f:viewParam id="item" name="item" value="#{myBean.item}"/>
        <f:event type="preRenderView" listener="#{myBean.init}" />
    </f:metadata>
</h:body>

The view param is set after your beans @PostConstruct method is invoked. So if you want to do some stuff based on the value, use the event preRenderView
