Don't want to be that a wacky answer, but I read the source - only free
hotspot for myself newby-level seemed to be (quoting
org.apache.struts.action.RequestProcessor):

    /**
     * General-purpose preprocessing hook that can be overridden as
required
     * by subclasses.  Return <code>true</code> if you want standard
processing
     * to continue, or <code>false</code> if the response has already
been
     * completed.  The default implementation does nothing.
     *
     * @param request The servlet request we are processing
     * @param response The servlet response we are creating
     */
    protected boolean processPreprocess(HttpServletRequest request,
                                        HttpServletResponse response) {

        return (true);

    }

...where myself subclassing had put sth like sample from book
"Programming Struts" :

  protected boolean processPreprocess( HttpServletRequest request,
                                      HttpServletResponse response){

    HttpSession userSession =3D request.getSession(false);
    // Check to see if there's a session for the user that wasn't just
created (or if he didn=B4t logged out - ? does session invalidate on his
browser as well ?)
    UserContainer uc =3D
(UserContainer)userSession.getAttribute(IAppConstants.USER_CONTAINER_KEY
);
    if ( uc =3D=3D null || userSession =3D=3D null || =
userSession.isNew()){
      //continueProcessing =3D false;
      try{
        userSession.invalidate();
        userSession =3D request.getSession(true);=20
        ApplicationContainer ac =3D
(ApplicationContainer)userSession.getServletContext().getAttribute(IAppC
onstants.APPLICATION_CONTAINER_KEY);
        userSession.setAttribute(IAppConstants.USER_CONTAINER_KEY, new
UserContainer(ac));
        response.sendRedirect( "/index.jsp" );
        return false;
      }catch( Exception ex ){
        ex.printStackTrace();
      }
    }
    return true;
  }

Hi,

I've been searching through the documentation to find information on
extending=20
the RequestProcessor class but can't seem to find it.  Can someone point
me=20
in the right direction?

Thanks in advance,
John
