How to access Action Mapping instance if session expires

[Puneet Vardhan]

Hi,
        How can I access the action mapping instance if session is expired?
I have a global forward in struts-config.xml which points to logon page

        <global-forwards>
        <forward   name="logon"  path="/logon.jsp"/>
        </global-forwards>

        in session expires  I need to forward to logon page 

        something like    if ( session == null ) mapping.findForward(logon);
        
        Is the ActionMapping object kept in session scope or application
scope?
Thanks
Puneet
