Forward method

Question

hi friends,
this is part of my frist jsp --
System.out.println("prevPageUrl@@@@@@@@@@@@@@@@@2222"+prevPageUrl); %>
     <jsp:forward page="../errorPages/subscriptionbounce.jsp">
          <jsp:param name="docassembid" value="<%= contentViewerHelper.getDocassembid() %>" />
          <jsp:param name="previouspage" value="<%=prevPageUrl%>"/>
          <jsp:param name="message" value="User <%= userProfile.getUserId() %> is traying to access to publication <%= contentViewerHelper.getPublication() %>"/>
     </jsp:forward>
i am getting "prevPageUrl" value as null. After forwarding this "subscriptionbounce.jsp" , i tried to get parameter "prevPageUrl" using request.getParameter("previouspage") method. the value i got is not null. instead its a empty string . i got this valuse using s.o.p(request.getParameter(previouspage). any suggestions here.

String previousPageUrl = request.getParameter("previouspage");
String pre= request.getParameter("previouspag");
       System.out.println("previousPageUrl@@@@@@@@@@@@@@@@@@"+previousPageUrl);
       System.out.println("pre@@@@@@@@@@@@@@@@@@"+pre);
       int i = previousPageUrl.length();
       System.out.println(i);
if (previousPageUrl == null ) {
        out.println("previousPageUrl@@@@@@@@@@@@@@@@@@"+previousPageUrl);
     previousPageUrl = request.getHeader("Referer");
     out.println("Referer@@@@@@@@@@@@@@@@@@@@@@@@@@@"+previousPageUrl);
     if (previousPageUrl == null) {
          previousPageUrl = CRNSearcherConst.JSPFILES.PROTECTED_PREFIX_URL + CRNSearcherConst.JSPFILES.HOME_PAGE; // redirect to the home page
if (!previousPageUrl.startsWith("javascript:"))
     previousPageUrl = PortalHelper.getPortalRootURL(session) + previousPageUrl;
String docassembid = request.getParameter("docassembid");
// TODO: implement more sophisticated handling of docassembid equals null
if (docassembid == null)
     docassembid = "not_specified";
