Subject RE: how to retrieve property values from previous forms/jsp pages
Date Mon, 03 Nov 2003 20:44:14 GMT
Thank David,

The second option may not work for me because the secondPage.jsp will be further
extends to hotel.secondPage.jsp, car.secondPage.jsp and so on. The purpose of the
finalPage.jsp is to echo all values that were inputted from either the hotel
group(firstpage.jsp and the hotel.secondPage.jsp), or the card group
(firstpage.jsp and the car.secondPage.jsp). Then the user have the option to
either submitted or goes back to the firstPage.jsp.  Thus I should not combine
the and into the (that becomes This will make the too difficult to maintains in the future. The third option
looks more fit into my situation?  How do i put the action's bean in the session
scope? Do you mean setting the scope to session in the action mapping. I thought
the scope setting was for the form bean. Can you give a simple code example? 
How do I retrieve the property values of firstForms in my execute method of the

   public ActionForward execute(ActionMapping mapping,
                                  ActionForm form,
                                  HttpServletRequest request,
                                  HttpServletResponse response)
                throws Exception {

      hotel.secondForm inputForm = (hotel.secondForm) form;
      // retrieve all property values


      //Now what to do to get the firstForm from here??
   } //end execute

May be I need to use the request.setAttribute to setup a DAO object in the and retrieve the DAO object from within the execute method of
the by using the request.getAttribute method? Can this be

Thank you in advance,
