SearchCriteria criteria = (SearchCriteria)command;
HttpSession session=request.getSession();
long from_date = criteria.getDateFrom()!=null?criteria.getDateFrom( ).getTime()/1000:0;
long to_date = criteria.getDateTo()!=null?Util.getToDate(criteria ):0;
int iMemberTypeId = Util.getProspectMemberTypeId(criteria.getProspectT ype()).intValue();
session.removeAttribute("reportFileName1");
StringBuffer url = new StringBuffer();
url.append("http://localhost:8080");
// url.append(request.getServerName());
Integer iMemberId= (Integer)session.getAttribute(SignUpConst.SIGNUP_A DMIN_ID);
if(iMemberId==null)
iMemberId=new Integer(-1);
if(WebUtils.hasSubmitParameter(request, "createReport")) {
if(criteria.getDateFrom() == null || criteria.getDateTo() == null ){
request.getSession().setAttribute("message", "You must enter Date From and Date To in the Follow Up Date Range section to produce a report.");
return new ModelAndView("redirect:contactSearchForm.html?type ="+criteria.getProspectType()+"&action="+criter ia. getAction());
}

session.setAttribute("searchCriteria",criteria);
ProspectWaitPage.mapReportId.put(iMemberId, new String("false"));
session.setAttribute("requestTime",new Long(System.currentTimeMillis()));
String strUrl = "/servlet/com.signup.prospect.webapp.action.ProspectWaitPage ";
RequestDispatcher rd = request.getRequestDispatcher(strUrl);
rd.forward(request,response);

// response.sendRedirect("http://" + request.getServerName()+ strUrl);
//+":"+request.getServerPort()

String res_clause = Util.setParameters(criteria);

String strReportFileName1 = url.toString()+strReportFileName;
request.getSession().setAttribute("reportFileName1 ",strReportFileName1 );
}

// RequestDispatcher rd = getServletContext().getRequestDispatcher(strUrl);
// rd.forward(request,response);
session.setAttribute("reportGenerated", "true");
