Although the typical design pattern is to return the result of calling
mapping.findForward(), you can also create your own instance:
String url = "/context/relative/path.do?name1=value1";
return (new ActionForward(uri));
so you can construct your own. If you don't want to give up the logical
naming feature of ActionForwards, you can do something only slightly more
complicated:
ActionForward forward = mapping.findForward("success");
String url = forward.getPath() + "?name1=value1";
return (new ActionForward(url));
