Thank you Dale, Let me see if I understand this correctly. Since the action object has not been created yet, and this is in a different thread... I can not get the correct context... Although the session objects _is_ someplace... It will also not work in the constructor even if the class is SessionAware because the object must exist before setSession(Map m) could be called...
So... I should really be treating execute() as my constructor for now... until I better understand when the session variable becomes available. Struts2 needs to see who I am before it knows my session right? So it isn't going to provide it to me until it has done a certain amount of set up? Ken.
