How can I notify the user that the session time has elapsed?

Question

I created a method in the bean

public void checkSessionLife() {
        if (FacesContext.getCurrentInstance().getExternalContext().getSession(false)==null) {
            System.out.println("*\n");
            System.out.println("destroyed");
            FacesContext.getCurrentInstance().addMessage("sessiongr", new FacesMessage(FacesMessage.SEVERITY_INFO, "erer", "errrrrrrrrr"));
            RequestContext requestContext = RequestContext.getCurrentInstance();
            requestContext.update(Arrays.asList("hreaderForm:sessiongr"));
        }
    }

and in my PgTemlate.xhtml i add a <p:poll> to update a <p:growl>

<p:poll interval="5" listener="#{accessBean.checkSessionLife()}" process="@this" global="false"/>
                <p:growl id="sessiongr" showDetail="true" sticky="true"/>

the problem is that the activity is seen as <p:poll> activity sessions There he has another method to notify the user?

What is the scope of accessBean? If it's anything less than application scope, I believe the function will fail to run, because JSF cannot find the bean.

Nonetheless, this isn't the recommended method for handling session expirations. For the preferred one, see BalusC's method.
