Hi, Thanx again for your answer :)
The problem is that I don't want to nest my ActionForm, I want them all treated as a unique session bean. Without them being into (dependant of) another ActionForm. >so you can retrieve them from other Actions/JSPs by >using request.getAttribute( <ActionForm logical name> ). I suppose you meant request.getSession().getAttribute( <ActionForm logical name> ), didn't you ? :) Friendly Regards, Slimane At 15:12 15/03/2002 -0800, Someone poor demented soul by the name of "Joseph Barefoot" presented us with the following text which may contain useless information. >Valid questions, all. :) I have to admit I'm not 100% sure when the >ActionForm bean is first instantiated/initialized, but this is what I think: >The ActionForm bean is created and initialized when the URI specified by the >action-mapping for this particular Action/ActionForm pair is requested. >(if this is incorrect, please someone correct me) > >If you want to share beans, just declare the scope to be "session" for the >bean in question in the action-mapping for this action inside >struts-config.xml.
