Parameters are values from the HTML form for example. Attributes can be
objects put there by a servlet which included this servlet to continue
processing.
So:
/servlet/Blah?smile=yes
will invoke Blah servlet and Blah says:
request.setAttribute("face",SmileyFaceObject);
getRequestDispatcher("/servlet/Blah2").include(request,response);
then Blah2 servlet still has access to parameter smile and also to object
called SmileyFaceObject through two different methods:
String smile = request.getParameter("smile");
Object SmileyFaceObject = request.getAttribute("face");
