Actually, you haven't illustrated it. You've just stated it. In the ActionForm there are methods like validate() that accept as parameters an ActionMapping and an httpServletRequest, and from the httpServletRequest you can call getSession().
Same holds true in the Action class' execute() method. So what is the problem with your class? Why can't you utilize it from one of these places that you do have access to these things? What exactly is stopping you here? Once you tell us, then you will have illustrated the problem. -J > -----Original Message----- > From: Caroline Jen [mailto:[EMAIL PROTECTED] > Sent: Saturday, December 06, 2003 1:47 PM > To: Struts Users Mailing List > Subject: Re: Very Troubled in Finding Ways to Pass a Variable > to a Class > > > I know how to pass a hidden field.
